    ABSTRACT: Micro- and nanoengineering of materials offer novel technologies and serve as an interface between material sciences and biomedical nanotechnology. Various techniques are used for the engineering of polymers, and it allows the precise orientation of biomolecules with designed nanoregions in a substrate, with defined sizes and continuity offering well featured substrate topographies. Methods such as the electron beam lithography coupled with microcontact printing have been applied for the fabrication of high resolution surface features that are smaller than the size of a cell. This review elaborates more deeply on the different methods used for the fabrication of patterned surfaces such as the photolithography, electron beam lithography, microcontact printing, soft lithography, capillary force lithography, and patterning of electrospun fibers. The nanoengineered substrates may have the ability to influence the differentiation of stem cells to specific lineages and here we survey a few details on the influence of surface topology and its potential for tissue regeneration.

    ABSTRACT: Bicomponent polycaprolactone/gelatin (PCL/Gt) nanofibers were successfully formed for the first time by electrospinning using a novel polymer–solvent system with solvents being alternative to the commonly used toxic solvents like fluorinated alcohols. The mixture of acetic acid (AA) with formic acid (FA; 90:10) was applied. Stable electrospinning was possible despite the fact the mixture of PCL and gelatin in AA/FA solvent showed emulsive structure. From the practical perspective, there is no doubt that it is possible to obtain PCL/Gt fibers using AA/FA mixture with morphology similar to that for fibers spun from hexafluoroisopropanol (HFIP) solutions.

    ABSTRACT: The effect of electrospinning parameters on morphology, molecular, and supermolecular structure of polycaprolactone (PCL) fibers was analyzed, with respect to tissue engineering applications. Fibers morphology and structure are mainly determined by solution concentration and collector type. Applied voltage does not significantly influence supermolecular structure (crystallinity) and mechanical stiffness. There is correlation between changes in structure and proliferation of 3T3 cells as evidenced by in vitro study. Processing window of optimal scaffolds is relatively wide, however, variation of electrospinning parameters do not significantly affect their biological functionality.

    ABSTRACT: The synthesis and characterization of conducting polyaniline (PANI) salt and nickel sulfide (NiS) hybrid composites are reported in this study. The PANI-NiS hybrid composites showed nearly two orders of magnitude higher than that of pure PANI. The specific conductivities of PANI and PANI-NiS hybrid composites (2% and 20% by weight) were found to be 5.1 × 10−4, 1.6 × 10−2, and 3.8 × 10−2 S/cm. The polarity of Hall voltage of the hybrid composite was found to be negative indicating that the PANI-NiS composite is an n-type semiconductor. The composites pellets were characterized by XRD, SEM and FTIR and the results were compared.

    ABSTRACT: Polyesters derived from the interfacial reaction of the salt of chelidonic acid and triphenylarsenic dibromide, triphenylantimony dichloride, and triphenylbismuth dichloride are formed in moderate yield using commercially available reactants. IR data shows new bands characteristic of the formation of the M-O bond. MALDI MS shows formation of ion fragment clusters to two units. The polymers were tested for their ability to inhibit prostate, colon, breast (two cell lines), and pancreatic (two cell lines) cancer cells. All polymers showed ability to inhibit some of the cancer cell lines. The arsenic polymer exhibits good inhibition of the AsPC-1 pancreatic cell line. All three polymers inhibit the estrogen independent 7233 cell line to a much greater extent compared to inhibition of the 7259 estrogen positive receptor cell line. The arsenic and bismuth polymers also exhibit decent inhibition of the other cancer cell lines while the antimony polymer shows only decent inhibition of the 3465 prostate cell line.

    ABSTRACT: The authors present the fabrication of electrospun nanofibers with antimicrobial properties by the UV-initiated grafting (photo-grafting) of 2-substituted vinylimidazoles onto nylon 6 nanofibers. The characterization was performed using IR spectroscopy (ATR-FTIR) and scanning electron microscopy (SEM-EDX). The antimicrobial properties of the grafted electrospun nylon 6 nanofibers were evaluated against Escherichia coli and Staphylococcus aureus as model challenge microorganisms, using the dynamic shake flask method. All the grafted electrospun nylon 6 nanofibers exhibited excellent growth reduction of E. coli (99.94–99.99%) and S. aureus (99.55–99.99%). The electrospun nylon 6 nanofiber composites could be used twice before a decrease in antibacterial activity was observed. The study showed that electrospun nylon 6 nanofiber composites possess a potential for use to control pathogens in water.

    ABSTRACT: The main drawback of direct methanol fuel cells is methanol crossover. One strategy to overcome this problem is design of new polymeric membranes. Two structurally different diols named as 4,4′-(1,4-phenylene diisopropylidene) bisphenol and 4,4′-(1,3-phenylene diisopropylidene) bisphenol (para- and meta-substituted monomers) were used to prepare two groups of poly(arylene ether sulfone)s with different structures and related membranes therefrom by solution casting. It was found that para- or meta-substitution positions in monomers affected the methanol permeability of membranes. Other influenced properties of resulted membranes such as ion exchange capacity, water uptake, proton conductivity, glass transition temperature, and mechanical strength were studied and compared.

    ABSTRACT: Poly(L-lactic acid) is prominent in biodegradable stent material research but its brittleness is a disadvantage. Poly(butylene succinate) (PBS) addition enhances ductility but there is a void in knowledge of degradation effects on PLLA/PBS blends—vital for evaluation of a potential stent material. Neat PLLA and melt-blended PLLA/PBS specimens were subjected to tensile testing, before and after degradation in buffered saline (37°C, pH 7.4), for up to 24 weeks. Additional specimens were subjected to constant-load creep tests. Tensile test results indicate that PLLA/PBS blends exhibit gradual losses of strengths and Young's moduli as they degrade whilst neat PLLA shows little change over a 24-week degradation period. Neat PLLA exhibits increasing creep resistance during the first eight weeks of degradation whilst the 75/25 wt% PLLA/PBS blend exhibits decreasing creep resistance with increasing degradation time. PLLA/PBS blends are ductile but creep resistance during degradation needs improvement for their use as biodegradable stent materials.

    ABSTRACT: The aim of this work was to prepare alginate base film and its properties and application in drug delivery field. In order to achieve this, naproxen as a drug and magnetic nanoparticles were placed into the films. Sodium alginate could be crosslinked and form a gel under extremely mild and environmentally friendly conditions without using toxic solvents and reactants. The polymeric films were analyzed by DSC, SEM, and FT-IR spectroscopy. The in vitro release profiles were established separately in both enzyme-free simulated gastric (pH 1) and intestinal fluids (pH 7.4).

    ABSTRACT: The effects of O-carboxymethylation modification on the coacervation of chitosan with gum arabic (GA) were investigated. O-carboxymethylated chitosan (O-CMC) carried less net positive charge in acidic solutions and its optimum pH and biopolymer ratio for coacervation with GA were lower than those of native chitosan. O-carboxymethylation modification decreased the optimum coacervation temperature from 45 to 25°C and greatly increased the sensitivity to ionic strength. Meanwhile, insoluble O-CMC–GA coacervates were formed in relative lower critical total biopolymer concentration than chitosan–GA coacervates. It was concluded that the O-carboxymethylation modification markedly influenced the electrostatic interaction of chitosan with GA.

    ABSTRACT: Herein, the authors report the synthesis of electro-magnetic polyfuran/Fe3O4 nanocomposites using Fe3O4 magnetic nanoparticles of different content as nucleation sites via in situ chemical oxidation polymerization method. Surface, structural, morphological, thermal, electrical and magnetic properties of the nanocomposites were studied by FT-IR, UV-visible spectroscopies, XRD, FESEM, TGA, four probe, and VSM, respectively. The effect of Fe3O4 nanoparticles content on the electrical conductivity and magnetization of nanocomposites was studied. The obtained polyfuran and polyfuran/Fe3O4 nanocomposites were analyzed for their antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. In addition, polyfuran/Fe3O4 nanocomposites have been investigated for application as electrochemical biosensor.

    ABSTRACT: The dental composites based on poly(methyl methacrylate)/hydroxyapatite (PMMA/HA) were prepared through heat-processing polymer powder-liquid method, in the presence of poly(lactic acid) powder (PLA; 5–20 phr). The PLA powder enhanced the flexural modulus and strength of PMMA/HA composites. The Alamar Blue assay results indicated the PMMA/HA/PLA composites were able to sustain human gingival fibroblasts (HGF) cells growth. The images of live/dead cells confocal showed the populations of living cells on the composites surface were confluent and the survival of HGF cells on the PMMA composites surface are assured. These features suggested that the PLA powder reinforced PMMA/HA composites demonstrated excellent biocompatibility.

    ABSTRACT: Sulfonated polyether ether ketone (SPEEK)/polyether sulfone (PES)/nano hydroxyapatite (nHAP) composites were prepared with different nHAP filler concentrations. FTIR analysis confirmed the blend formation between SPEEK and PES. Surface morphology pictures showed agglomeration of the nHAP particles at higher percentage of loading. Evaluation of the tensile property showed that composites with 4 and 6 wt% of nHAP displayed the maximum tensile strength. The in vitro drug release study, performed with amoxicillin, indicated that these composites retained slightly less than 50% of the initial drug loaded. The in vitro bioactivity was observed to increase with increase in filler concentrations. The in vitro cytotoxicity test performed using osteoblast like cells (MG 63 cell line) by MTT method suggested that the composite having 6 wt% of filler loading was the most favourable. The results of the study show that these composites could be used for filling of orthopedic defects in non–load-bearing areas of bone.

    ABSTRACT: Novel double-hydrophilic block copolymers, acrylic acid (AA)-2-acrylamido-2-methyl-propane sulfonate (AMPS)-oxalic acid-allypolyethoxy carboxylate (APEM) was specially designed and synthesized from allyloxy polyethoxy ether (APEG) to inhibit the precipitation of CaCO3 and CaSO4. The structure of the copolymer was characterized by FT-IR and H1-NMR. Using the static experiment method, the scale inhibition efficiencies for CaCO3 and CaSO4 scale were investigated. It was shown that AA-AMPS-APEM exhibited excellent ability to control inorganic minerals scales, with approximately 97.1% CaSO4 inhibition and displayed significant ability to prevent the formation of CaCO3 scales. The synthesized AA-AMPS-APEM was also compared with that of current commercial inhibitors. The effect of the copolymer addition on the crystals of CaCO3 and CaSO4 scales morphology and structures were examined through scanning electron microscope (SEM), transmission electron microscope (TEM), and X-ray diffraction studies (XRD). It proved that great changes in the size and morphology of the calcium scales took place under the influence of AA-AMPS-APEM. The proposed inhibition mechanism suggests the formation of complexes between the side-chain carboxyl groups of AA-AMPS-APEM and calcium ions on the surface of inorganic minerals, and the excellent solubility of complexes resulted from a number of hydrophilic polyethylene glycol (PEG) and sulfonic group (-SO3H) group.

    ABSTRACT: Chitosan scaffold has potential use in the controlled release of drugs, and as 3-D structure for the formation of tissue matrix. This article describes the solute release behavior of chitosan scaffold that bears embedded voids of submillimeter dimensions. Formaldehyde and glyoxal were considered as crosslinkers, and alcohol ethoxylate was used as the surfactant. Nitrogen gas was bubbled in a fluidic arrangement to generate an ensemble of self-aligned bubbles in chitosan, prior to the crosslinking. The crosslinked gel was dried in a vacuum oven, and subsequently, the absorption capacity of the scaffold in PBS buffer was estimated. The type of crosslinker significantly affected the absorption capacity of the scaffold. The dimensions of the voids immediately after the cross-linking of gel, and also after complete drying were obtained using a digital microscope and a scanning electron microscope respectively. Two levels of porosity are evident from these images. The smaller pores were intrinsically provided by the gel matrix. The larger ones were induced by the fluidic arrangement. The porosity of the gel was measured gravimetrically. The uptake of Vitamin B-12 was found significantly higher when formaldehyde was used as crosslinker instead of glyoxal. The release of Vitamin B-12 in PBS buffer on a shaker was studied. For comparison, the experiment was repeated with a scaffold that did not have any embedded void. The enhancements in the release of Vitamin B-12 due to the presence of voids are estimated in this article. The bubbles, placed in more than one layer, enhanced the porosity and the ability to absorb Vitamin B-12 further.

    ABSTRACT: Extensive research has been carried out for developing nanocarriers to overcome the major barriers preventing success in oral insulin therapy, which includes (a) identification of in vivo barriers, (b) incorporation of prerequisite characteristics into single nanocarrier, and (c) exclusion of the use of additional potentially toxic chemicals as enzyme inhibitors or permeation enhancers. The present review identifies the prerequisite characteristics of single nanocarrier that could avoid major hindrance being faced in oral insulin delivery. An effort is made to discuss the involvement of prerequisite characters to overcome the major hurdles, which prevent the success in oral insulin delivery.

    ABSTRACT: Recently, polymersomes self-assembled from amphiphilic block copolymers have attracted considerable interests with superior physicochemical properties. Here, the biotinylated block copolymers were blended with unmodified block copolymers to produce biotinylated polymersomes via film rehydration. Then, the avidin molecules were attached onto the biotin molecules covalently linked with block copolymers to form surface functionalized vesicles that are capable of carrying various biotinylated bioactive molecules, generating a relatively universal delivery platform. Hydrophobic fluorophores DAF and Nile Red were encapsulated respectively into hydrophobic membrane to prepare hydrophobic substances loaded polymersomes for investigating the nature of hydrophobic functionalization. Furthermore, the hydrophobic functionalized DiR-polymersomes were employed to perform in vivo imaging to survey the in vivo behavior for nano-polymersomes with hydrophobic functionalization.

    ABSTRACT: Biocompatible polyvinyl alcohol/polyethylene glycol and polyvinyl alcohol/polypropylene glycol copolymer mats were prepared by electrospinning. The composite fiber mats were subjected to detailed physical analysis complemented by scanning electron microscopy and Fourier transformations infrared spectroscopy. Scanning electron microscopy images showed that the morphology and diameters of the fibers were mainly affected by the types of polymers and their copolymer compositions. Microbial culture results showed that among the tested fibrous mats polyvinyl alcohol/50% polyethylene glycol gave the best results in preventing the cell attachment and proliferation. This novel electrospun matrix would be used as potential wound dressing material for skin regeneration.
