Polímeros termorresponsivos: principais características do hidrogel e aplicações biomédicas
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosQuímica - Q, 2022-09-30)
The need to improve efficiency in drug administration has resulted in incentives in scientific research for the development of new materials with biomedical applications that can act in vivo, allowing the release of drugs ...
Polymeric nanocomposites made of a conductive polymer and a thermosensitive hydrogel: Strong effect of the preparation procedure on the properties
(Elsevier, 2015-11)
Nanocomposites are made by loading a conductive polymer (polyaniline, PANI) inside a thermosensitive hydrogel matrix (poly(N-isopropylacrylamide)-co-(2-acrylamido-2-methylpropane sulfonic acid), HG). The composites were ...
Thermoresponsive hydrogels based on alginate-g-poly(N-isopropylacrylamide) copolymers obtained by low dosis of gamma radiation
(Elsevier, 2015-04-17)
Low doses of gamma radiation from 60Co have been used in the synthesis of water soluble alginate-g-poly(N-isopropylacrylamide) (PNIPAAm) copolymers. Irradiation was carried out using glass vials containing aqueous solutions ...
Hidrogéis Nanocompósitos Termossensíveis aplicados no crescimento de Células–tronco Mesenquimais e Condrócitos para a engenharia tecidual
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2018-09-27)
Injectable biomaterials have gained prominence in tissue engineering since they present a minimal invasive option for therapeutic delivery. However, longer gelation time, instability of physicochemical properties, cytotoxicity ...
Synthesis, characterization and slow drug delivery of hydrogels based in N-acryloyl-tris-(hydroxymethyl) aminomethane and N-isopropyl acrylamide
(Elsevier Science, 2011-04)
In this study, new hydrogels in rod shape were prepared from N-isopropyl acrylamide (NIPA), N-acryloyl-tris-(hydroxymethyl) aminomethane (NAT) and N,N´-methylenebisacrylamide (BIS). The effect of the incorporation of NAT ...
