Amphiphilic poly(3-hydroxylalkanoate) (PHA) copolymers find interesting applications in drug delivery. The aim of this study was to prepare nucleic acid adsorbed on (PHB-b-PEG-NH2) nanoparticle platform for gene delivery. For this purpose, PHB-b-PEG-NH2 block copolymers were synthesized via transesterification reactions. The copolymers obtained were characterized by Proton Nuclear Magnetic Resonance (1H-NMR), Fourier Transform Infrared Spectrometer (FTIR), Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) techniques. The cytotoxic, apoptotic and necrotic effects of these nanoparticles in the MDA 231 human . . .breast cancer cell, the A549 human lung cancer cell and the L929 fibroblast cell lines were also investigated. © 2015 Taylor & Francis Daha fazlası Daha az

The synthesis and characterization of novel quinone-amine polymers from the reactions of 2,3-dichloro-1,4-naphthoquinone and polyoxypropylenediamines

A series of novel N-and N,N'-bis(quinonyl)amines were synthesized from the reactions of 2,3-dichloro-1,4-naphthoquinone (1) and polyoxypropylenediamines. The novel quinone-amine polymers were treated with some thiols in next step and N,S-substituted compounds were obtained. The structures of the novel products were characterized by micro-analysis, 1H NMR, UV-VIS, 13C NMR, and MS. The electrochemical properties of some of the novel amine-quinone polymers derivatives were also investigated by cyclic voltammetry. The number of molecular weight (Mn) of polymer compounds was also determined by Gel Permeation Chromatography (GPC). © 2016 . . .Taylor & Francis Group, LLC Daha fazlası Daha az

Design of a mediated enzymatic fuel cell to generate power from renewable fuel sources

Article | 2016 | Environmental Technology (United Kingdom)37 ( 2 ) , pp.163 - 171

The present work reported a compartment-less enzymatic fuel cell (EFC) based on newly synthesized Poly(pyrrole-2-carboxylic acid-co-3-thiophene acetic acid) film containing glucose oxidase and laccase effectively wired by p-benzoquinone incorporated into the copolymer structure. The resulting system generated a power density of 18.8 µW/cm2 with 30 mM of glucose addition at +0.94 V at room temperature. Improvements to maximize the power output were ensured with step-by-step optimization of electrode fabrication design and operational parameters for operating the system with renewable fuel sources. We demonstrated that the improved fu . . .el cell could easily harvest glucose produced during photosynthesis to produce electrical energy in a simple, renewable and sustainable way by generating a power density of 10 nW/cm2 in the plant leaf within 2 min. An EFC for the first time was successfully operated in municipal wastewater which contained glycolytic substances to generate electrical energy with a power output of 3.3 µW/cm2. © 2015 Taylor & Francis Daha fazlası Daha az

Potent bioactive bone cements impregnated with polystyrene-g-soybean oil-AgNPs for advanced bone tissue applications

Postoperative infection in orthopaedic and trauma surgery is one of the most feared complications. Recently, the high prevalence of multidrug-resistant bacteria has made the antibiotic treatment ineffective; thus novel non-antibiotic alternative approaches to this problem are urgently needed. Based on these expectations, in this work, in order to enhance the cytocompatibility and antibacterial performances of poly (methyl methacrylate (PMMA) and beta-tricalcium phosphate (ß-TCP) bone cements were impregnated with polystyrene (PS)-g-soybean oil graft copolymer containing AgNPs (PS-Agsbox), and we assessed the antimicrobial activity o . . .f the fabricated bone cements against Staphylococcus aureus and Escherichia coli. Nanoparticles at concentration of 1.25% (5 ß-TCP) w/w in ß-TCP bone cements were able to inhibit pathogens growth, while a concentration of 3.75% (15PMMA) was needed for PMMA bone cement. Therefore, the impregnated bone cements with PS-AgsboxNPs may be further explored as an alternative antimicrobial therapy for the treatment of infected bone defects. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group Daha fazlası Daha az
