Surface modification of electrospun cellulose acetate nanofibers via RAFT polymerization for DNA adsorption
(ELSEVIER SCI LTD, 2014)
We report on a facile and robust method by which surface of electrospun cellulose acetate (CA) nanofibers can be chemically modified with cationic polymer brushes for DNA adsorption. The surface of CA nanofibers was ...
Cyclodextrin-grafted electrospun cellulose acetate nanofibers via "Click" reaction for removal of phenanthrene
(ELSEVIER SCIENCE BV, 2014)
Beta-cyclodextrin (p-CD) functionalized cellulose acetate (CA) nanofibers have been successfully prepared by combining electrospinning and "click" reaction. Initially, p-CD and electrospun CA nanofibers were modified so ...
Synthesis, structure characterization and antimicrobial evaluation of 4-(substituted phenylazo)-3,5-diacetamido-1H-pyrazoles
(PERGAMON-ELSEVIER SCIENCE LTD, 2013)
The present article deals with the synthesis, spectral characterization and antimicrobial activity of phenylazo dyes. All of the synthesized phenylazo dyes were characterized using ATR-FTIR, FT-Raman, H-1 NMR, C-13 NMR, ...
Novel pH-responsive mixed-charge copolymer brushes based on carboxylic acid and quaternary amine monomers
(WILEY-BLACKWELL, 2013)
In this study, we report on the fabrication of tunable mixed-charged copolymer brushes consisting of negatively charged carboxylic acid monomer (4-vinylbenzoic acid, VBA) and positively charged quaternary amine monomer ...
pH-responsive nanofibers with controlled drug release properties
(ROYAL SOC CHEMISTRY, 2014)
Smart polymers and nanofibers are potentially intriguing materials for controlled release of bioactive agents. This work describes a new class of pH responsive nanofibers for drug delivery systems with controlled release ...
RAFT-mediated synthesis of cationic poly[(ar-vinylbenzyl)trimethylammonium chloride] brushes for quantitative DNA immobilization
(ELSEVIER SCIENCE BV, 2013)
The synthesis of cationic polyl(ar-vinylbenzyl)trimethylammonium chloride)] [poly(VBTAC)] brushes was achieved via reversible addition-fragmentation chain transfer (RAFT) polymerization and used for quantitative DNA ...
Surface chemical conversion of 3-glycidoxypropyldimethylethoxysilane on hydroxylated silicon surface: FT-IR, contact angle and ellipsometry analysis
(PERGAMON-ELSEVIER SCIENCE LTD, 2012)
The chemical conversion of the top surface of 3-glycidoxypropyldimethylethoxysilane (GPDMES) on hyroxylated silicon surface has been studied as a function of reaction time. A multiple-step procedure was applied in this ...
Determination of pK(a) of benzoic acid- and p-aminobenzoic acid-modified platinum surfaces by electrochemical and contact angle measurements
(SPRINGER INTERNATIONAL PUBLISHING AG, 2012)
Acidity constant values of benzoic acid (BA)-modified platinum electrode (Pt-BA) and p-aminobenzoic acid (pABA)-modified platinum electrode (Pt-NHBA) surfaces were determined using cyclic voltammetry (CV), electrochemical ...
Controlled grafting of cationic poly[(ar-vinylbenzyl)trimethylammonium chloride] on hydrogen-terminated silicon substrate by surface-initiated RAFT polymerization
(ELSEVIER SCIENCE BV, 2012)
Controlled grafting of well-defined cationic poly[(ar-vinylbenzyl)trimethylammonium chloride] [poly (VBTAC)] brushes on a hydrogen-terminated silicon substrate (Si-H) was performed via surface-initiated RAFT polymerization. ...
A switchable polymer brush system for antifouling and controlled detection
(ROYAL SOC CHEMISTRY, 2017)
A stimuli-responsive polymer brush system is designed to switch on and off surface functionality and prevent functional groups from fouling by grafting together two polymer brushes with precisely controlled lengths. The ...
