Thermoreversible gelation
Webb24 jan. 2024 · The obtained gels have a gelation time of <15 min at a physiological temperature and pH, and possess a Young’s modulus similar to that of brain tissue (1–3 kPa). The disulfide bonds in the hydrogel were degradable in the presence of thiols (which are naturally occurring in the biological environment) and demonstrated the ability to … WebbIn vitro antibacterial activities of AgSD/NSs and AgSD/NS loaded gel were also measured. Results: Stable AgSD/NSs with an average particle size of 369 nm were formulated while 1.5% P407 was selected as a stabilizer. The optimized AgSD/NS thermoresponsive hydrogel exhibited the gelation temperature of approximately 30°C.
