15 صفحه اولIn situ-forming hydrogels--review of temperature-sensitive systems.
In the past few years, an increasing number of in situ-forming systems have been reported in the literature for various biomedical applications, including drug delivery, cell encapsulation, and tissue repair. There are several possible mechanisms that lead to in situ gel formation: solvent exchange, UV-irradiation, ionic cross-linkage, pH change, and temperature modulation. The thermosensitive ...
متن کاملSynthesis of pH Sensitive Hydrogels Based on Poly Vinyl Alcohol and Poly Acrylic Acid
In this research, hydrogels based on poly vinyl alcohol and poly acrylic acid blend were prepared which were cross-linked by applied thermal conditions. Afterward, effects of time and heating on water uptake were investigated. The highest water uptake value exhibited by the sample that was heated for 20 min. at 110 ºC was about 2129% after 4 days at equilibrium state. Hydrogels exhibited p...
متن کاملFrontal polymerization synthesis of temperature-sensitive hydrogels.
The study of hydrogels and their response to external environment is of special interest because of their potential as drug delivery systems,1,2 actuators,3 and separation devices.4,5 Temperature-sensitive hydrogels undergo a reversible swellingdeswelling transition with a small change of temperature near the phase transition point.6 A frequently studied thermosensitive hydrogel is based on sol...
متن کاملDually cationic and anionic pH/temperature-sensitive injectable hydrogels and potential application as a protein carrier.
Novel copolymers containing both anionic and cationic pH-sensitive moieties were reported. These amphoteric copolymers exhibited special closed-loop reversible sol-gel-sol phase transitions in response to both pH and temperature.
