The chemical structure of PIA characterized by FTIR and 1H NMR manifested the successful introduction of IA into PIA chains. The increase of IA content increased the particle size from 101.9 to 327.6 nm and lowered the ZET...

Chitosan functionalised poly(ε-caprolactone) nanofibrous membranes as potential anti-adhesive barrier films
Publication date: Available online 5 July 2019Source: Reactive and Functional PolymersAuthor(s): Ying Mao, Noor Sanbhal, Yan Li, Chenglong Yu, Fujun Wang, Robert Guidoin, Jing Gao, Lu WangAbstractAbdominal adhesion could be minimised by introducing an anti-adhesive barrier between the injured site and the surrounding tissue or organ. Here, we propose an electrospun poly(ε-caprolactone) (PCL) nanofibrous membranes (NFMs) functionalised with chitosan that would be an alternative to current anti-adhesion barrier films. Oxygen plasma was applied to treat PCL NFMs to improve surface wettability in case of chitosan funct...

Poly(amino acid)-grafted polymacrolactones. Synthesis, self-assembling and ionic coupling properties
Publication date: Available online 4 July 2019Source: Reactive and Functional PolymersAuthor(s): E. Tinajero-Díaz, A. Martínez de Ilarduya, B. Cavanagh, A. Heise, S. Muñoz-GuerraAbstractPolyglobalide (PGl) with number average polymerization degree of ~20 was prepared by enzymatic ROP and then polyfunctionalized at 60% with aminothioethylene groups. The PGl20-(NH2)12 copolymer was used as macroinitiator for the ROP of NCAs of BLG (γ-benzyl L-glutamate) and ZLL (εN-carbobenzoxy-l-lysine) protected amino acids to produce neutral polypeptide-grafted polyglobalides poly[Gl20-graft-(AA)z] with ...

New immobilization method of anti-PepD monoclonal antibodies for the detection of Listeria monocytogenes p60 protein – Part B: Rapid and specific sandwich ELISA using antibodies immobilized on a chitosan/CNC film support
Publication date: Available online 5 July 2019Source: Reactive and Functional PolymersAuthor(s): Marie-Christine Etty, Sabato D'Auria, Shiv Shankar, Stephane Salmieri, Carole Fraschini, Monique LacroixAbstractThis paper presents the application of a new support based on chitosan and reinforced with cellulose nanocrystals (m-CCG) for the detection of Listeria monocytogenes p60 protein in sandwich ELISA. This support consists of biopolymer membrane optimized for the covalent immobilization of the specific monoclonal antibodies against the unique short peptide of eleven amino acids (PepD, QQQTAPKAPTE) of L. monocytogenes p60 ...

Selective adsorption of cationic dyes from colored noxious effluent using a novel N-tert-butylmaleamic acid based hydrogels
Publication date: September 2019Source: Reactive and Functional Polymers, Volume 142Author(s): Pinar Ilgin, Hava Ozay, Ozgur OzayAbstractThe present research offers an innovative cyclic approach to cleaning colored water of toxic dyes due to the increased need for pure and safe water. Novel anionic hydrogels were fabricated via free radical copolymerization method in the presence of acrylamide or 2-hydroxyethyl methacrylate as neutral comonomer and N-tert-butylmaleamic acid as anionic monomer with the addition of N,N′-methylenebisacrylamide as cross-linker. Hydrogels were examined for morphology and chemical structur...

Microfluidics and hydrogel: A powerful combination
Publication date: Available online 3 July 2019Source: Reactive and Functional PolymersAuthor(s): Carla B. Goy, Roberto E. Chaile, Rossana E. MadridAbstractMicrofluidics is a very useful and promising technology that allowed engineering a huge variety of developments in several fields, such as biology, biomedical engineering, biotechnology, biochemistry, medicine and tissue engineering, among others. Moreover, when microfluidic is combined with hydrogel, the possibilities seem to be limitless. However, it is not found in the bibliography any report that shows the wide range of developments and application fields of this com...
