WebbThe rheological melting point of 58 °C is close to the gel melting point obtained from DSC. The system shows a strong influence of pH on gelation. An FTIR study indicates H-bond formation between the >C═O group of gallic acid and the −NH2 group of melamine. 1H NMR spectra indicate the presence of π−π stacking in the gel. 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.
