We demonstrate the formation of three morphologies relevant for integration with miniaturized devices-microscale pillars, conformal coatings, and self-supported membranes-via template-directed self-organization of lead telluride (PbTe) colloidal nanocrystals (NCs). Optimizing the self-organization process towards producing one of these morphologies...

Fabrication of materials for current energy applications is one of the most exciting areas of contemporary materials research. Over the past few years, the oldest perovskites and their related materials stay in the frontline of this research, yielding advancements to photovoltaic, optoelectronic, and laser technologies. Previously, familiar zero-di...

Bottom-up fabrication of thermoelectric (TE) materials from colloidal nanocrystal (NC) building blocks can substantially increase their TE efficiency, e.g., by reducing lattice thermal conductivity. In this work, 10-nm spherical phase-pure oleate-capped PbTe NCs with narrow size distribution were synthesized and employed to fabricate 50-nm thick fi...
Article
Experimental data have demonstrated the neuroprotective potential of cyclosporine A (CsA), however, its clinical usage as neuroprotectant is limited due to poor blood-brain barrier permeability and potential peripheral and central toxicity. In order to overcome these limitations, the nanoparticulate CsA delivery technology has been recently propose...

Foodborne diseases are an important cause of morbidity and mortality. According to the World Health Organization, there are 31 main global hazards, which caused in 2010 600 million foodborne illnesses and 420000 deaths. Among them, Salmonella spp. is one of the most important human pathogens, accounting for more than 90000 cases in Europe and even...
Article
The main goal of the presented research was to investigate the biocompatibility of polycaprolactone (PCL)-based nanoparticles and to evaluate the neuroprotective action of the encapsulated, water-insoluble neuroprotective substance − undecylenic acid (UDA). The neuroprotectant-loaded nanoparticles (NPs) were prepared from polymer containing toluene...
Article
Enterovirus 71 (EV71) is a major public health threat that requires rapid point-of-care detection. Here, we developed a surface-enhanced Raman spectroscopy (SERS)-based scheme that utilized protein-induced aggregation of colloidal gold nanostars (AuNS) to rapidly detect EV71 without the need for fabricating a solid substrate, Raman labels or compli...
Article
Synthesis of theranostic nanoparticles, which combine both therapeutic and diagnostic capabilities in one platform can be considered as a step forward personalized medicine, since it allows tracing the delivery of the drug to targeted organ. Thus, the aim of this work was to prepare gadolinium alginate gel nanoparticles (gadolinum nanogels - GdNG)...
Article
Poor water solubility and low bioavailability of lipophilic drugs can be potentially improved with the use of delivery systems. In this study, encapsulation of nanoemulsion droplets was utilized to prepare curcumin nanocarriers. Nanosize droplets containing the drug were encapsulated in polyelectrolyte shells formed by the layer-by-layer (LbL) adso...

Calcitriol (1,25-dihydroxyvitamin D3), an active metabolite of vitamin D3, besides the role in calcium and phosphorus metabolism, plays a role in maintaining the functions of the brain. Active forms of vitamin D3 stimulate neurotrophic factors' expression, regulate brain immune processes, and prevent neuronal damage. Therefore, a potential utility...
Article
The main objectives of the present study were to investigate the biocompatibility of polyelectrolyte-coated nanocapsules and to evaluate the neuroprotective action of the nanoencapsulated water-insoluble neuroprotective drug-undecylenic acid (UDA), in vitro. Core-shell nanocapsules were synthesized using nanoemulsification and the layer-by-layer (L...
Article
Undecylenic acid (UDA), a naturally occurring 11-carbon unsaturated fatty acid has been used for several years as an economical antifungal agent and a nutritional supplement. Recently, the potential usefulness of UDA as a neuroprotective drug has been suggested based on the ability of this agent to inhibit μ-calpain activity. In order to verify neu...
Article
The emulsion-core and polyelectrolyte-coated nanocapsules, designed as water-insoluble neuroprotective drug delivery system, were synthesized using layer-by-layer saturation method. The isopropyl myristate was used as oil phase and docusate sodium salt as emulsifier. For the polyelectrolyte shell preparation, synthetic polyelectrolytes, cationic (P...
Article
The adsorption kinetics of mixtures of a biosurfactant Quillaja Bark Saponin (QBS) with a globular protein, β-lactoglobulin (β-LG) at the water/air and water/tetradecane interfaces was investigated by measuring dynamic interfacial tension with axisymmetric drop shape analysis (ADSA) and maximum bubble pressure (MBP) techniques. With bulk concentrat...

The electrostatic interactions between dicephalic-type surfactants: cationic, N,N-bis[3,3'-(trimethylammonio)propyl]dodecanamide dimethylsulphate (C(12)(TAPAMS)(2)) and anionic, disodium N-dodecyliminodiacetate (C(12)(COONa)(2)) with oppositely charged polyelectrolytes, natural, λ-carrageenan (CAR) and synthetic, poly(diallyldimethylammonium chlori...
Article
The short- and mid-term adsorption kinetics of Quillaja Bark Saponin (QBS) biosurfactant at water–air interface was studied using a maximum bubble pressure and drop shape analysis techniques, respectively. The low values of diffusion coefficients at initial and close-to equilibrium stages of adsorption suggest that adsorption of QBS is mixed-diffus...
