Circulating tumor cells (CTCs), secreted from primary and metastatic malignancies, hold a wealth of essential diagnostic and prognostic data for multiple cancers. Significantly, the information contained within these cells may hold the key to understanding cancer metastasis, both individually and fundamentally. Accordingly, developing ways to ident...
Article
A colonic drug delivery system was developed to specifically deliver 5-aminosalicylic acid (5-ASA) to the inflamed site by conjugating with hemoglobin nanoparticles (HbNPs). The 5-ASA-HbNPs (eight 5-ASA molecules per Hb molecule) with the size of 220 nm and zeta potential of −14.6 mV is a tailored nanoparticle able to pass through the mucus layer....
Article
This review discusses recent advances and the reported strategies over the last ten years on the use of carbon-based quantum dots (QDs), including carbon dots (CDs), graphene quantum dots (GQDs), and polymer dots (PDs) in the design of fluorescence imaging and biosensing system for early diagnosis of cancers. Besides, this study comprehensively rep...
Article
Pseudomonas aeruginosa is the most common pathogen that causes chronic lung infections and recurrence of the disease in cystic fibrosis patients by hiding inside cells and biofilm matrix. Herein, we developed gentamicin and curcumin-loaded lipid-polymer hybrid nanoparticle- (termed CG-HNPs) to evaluate in vitro activities against biofilm-embedded P...
Article

Design and development of novel nanobiomaterials with multifunctional properties hold the promise of new therapeutic strategies to improve the current clinical research in the field of tissue engineering and regenerative medicine. Here, we have successfully synthesized novel autofluorescent hydroxyapatite (HAP) using a template-assisted assembly pr...
Article
Imidazolium-based ionic liquid functionalized PEGylated mesoporous silica nanoparticles MCM-41 (denoted as [ImIL-PEGylated@MCM-41] NPs) is synthesized and evaluated as an efficient and reliable pH-sensitive nano-carrier for controlled release of cationic Lapatinib (Lap) drug. This nano-DDS was fully characterized by dynamic light scattering, scanni...
Article
Full-text available
The low membrane permeability of lipophilic drugs was resolved using liposomes as a solubilizing agent and the precise size control of them is a significant parameter in drug carrier technology. Here, we have established a microfluidic octanol-assisted liposome assembly method to produce a surfactant-assisted liposome which has merged by the cytosk...
Article
A new method based on fluorescent probe of iron quantum cluster has been proposed for rapid detection of Escherichia coli (E. coli). The iron quantum cluster was synthesized using hemoglobin as both a source of iron and a protective agent (Hb-FeQCs). The investigation of the sensitivity of Hb-FeQCs towards metal ions showed a highly selective turn...

Microfluidics cell-based assays require strong cell-substrate adhesion for cell viability, proliferation, and differentiation. The intrinsic properties of PDMS, a commonly used polymer in microfluidics systems, regarding cell-substrate interactions have limited its application for microfluidics cell-based assays. Various attempts by previous resear...
Article
The ability to identify and enrich target cells can play a significant role in biosensing in general. For the separation of rare cells; a biosilica structure was extracted from “Chaetoceros sp.” diatoms as a novel natural source of mesoporous materials. These diatoms had special optical capabilities, especially in fluorescence emission. Biosilica s...
Article
The endostatin protein is a potent inhibitor of angiogenesis and tumor growth. The anti-angiogenic and antitumor properties of full-length endostatin can be mimicked by its N-terminal segment, including residues 1-27. Therefore, our previous studies have shown that a mutant N-terminal peptide which the Zn-binding loop was replaced by a disulfide lo...
Article
Host defense peptides selectively kill bacterial and cancer cells (including those that are drug-resistant) by perturbing the permeability of their membranes, without being significantly toxic to the host. Coulombic interactions between these cationic and amphipathic peptides and the negatively charged membranes of pathogenic cells contribute to th...
Article
Graphene quantum dots (GQDs) represent a new generation of graphene-based nanomaterials with enormous potential for use and development of a variety of biomedical applications. However, up to now little studies have investigated the impact of GQDs on human health in case of exposure. GQDs were synthesized from citric acid as carbon precursor by hyd...
Article
Hydrogen peroxide (H2O2) is one of the main source of oxidative stress and a typical marker of reactive oxygen species (ROS)-associated diseases. Therefore, selective detection and scavenging of overproduced H2O2 provide enormous benefits to the successful treatment of ROS-related diseases. The authors took advantage of this property to detect canc...
Article
A novel fundamental understanding of the features of mechanism for the synthesis of luminescent silver nanoclusters (AgNCs) in human hemoglobin (Hb) as capping/reducing agent based upon simultaneously size transition and fluorescence enhancement phenomena is presented. The interesting features consist of both NC core oxidation and aggregation-induc...
Article

The authors describe a novel water-soluble, stable, biocompatible, and highly fluorescent probe consisting of iron quantum clusters incorporated into human adult hemoglobin (Hb-FeQCs). The Hb-FeQCs were characterized by various spectroscopic techniques. The probe displays strong absorption and yellow fluorescence with a peak centered at 567 nm (pho...

The interaction of lipid environments with the type I' β-turn peptide structure called CSF114 and its N-glucosylated form CSF114(Glc), previously developed as a synthetic antigenic probe recognizing specific autoantibodies in a subpopulation of multiple sclerosis patients' serum, was investigated by fluorescence spectroscopy and electrochemical exp...
Article
In the present work the chemiluminescence characteristics of a peroxyoxalate system using berberine as a novel fluorophore has been investigated. Berberine can accept energy via the formation of a dioxetane and emits intense yellow light. The characteristics of the chemiluminescence for this system under various concentrations of reagents including...

A new fluorogenic method for selective and sensitive determination of beryllium using 2,6-diphenyl-4-benzo-9-crown-3-pyrane (DBCP) was developed. The proposed fluorescent probe undergoes fluorescent emission intensity enhancement upon binding to beryllium ions in MeOH/H(2)O (70:30, v/v) solution. The fluorescence enhancement of DBCP is attributed t...

Fluorescence enhancement of N, N-bis(salicylidene)-naphthylene-1,8-diamine (L) has been used to detect trace amounts of mercury ion in ethanol–water solution. The fluorescent emission intensity of the probe enhances upon binding to mercury ions. The fluorescence enhancement of L is attributed to a 1:1 complex formation between L and Hg2+ ion. This...
