RAFT preparation and self-assembly behavior of thermosensitive triblock PNIPAAm-b-PODA-b-PNIPAAm copolymers

Colloid and Polymer Science, 2016
A series of well-defined thermoresponsive ABA-type triblock copolymers poly(N-isopropylacrylamide)-b-poly(n-octadecylacrylate)-b-poly(N-isopropylacrylamide) (PNIPAAm-b-PODA-b-PNIPAAm) consisting of two blocks of PNIPAAm and one block of PODA in different ratio are prepared via reversible addition-fragmentation chain transfer (RAFT) polymerization.

Biocompatibility of thermo‐responsive PNIPAAm‐PLLA‐PNIPAAm triblock copolymer as potential drug carrier

Polymers for Advanced Technologies, 2015
This work aims to evaluate the cytocompatibility and hemocompatibility of thermo‐responsive polymers as potential drug carrier. Thermo‐responsive poly(N‐isopropyl acrylamide) (PNIPAAm) and poly(N‐isopropyl acrylamide)‐poly(l‐lactide)‐poly(N‐isopropyl acrylamide) (PNIPAAm‐PLLA‐PNIPAAm) triblock copolymer were synthesized by atom transfer radical ...

Novel renewable immunosensors based on temperature-sensitive PNIPAAm bioconjugates

Biosensors and Bioelectronics, 2008
A novel renewable immunosensor was created comprising a temperature-controlled surface composed of poly(n-isopropylacrylamide) (PNIPAAm)-antibody conjugates that could reversibly bind the antigen. Bovine serum albumin (BSA) and the corresponding antibody (anti-BSA) were chosen as a model antibody-antigen system to demonstrate the concept. The thermally
