The design of liquid crystalline hydrogels knitted with silver nanoparticles in macroscopic ordering is becoming a subject of research interest due to their promising multifunctional applications in biomedical and optoelectronic applications. The present work describes the development of liquid crystalline Schiff-based hydrogel decorated with silver nanoparticles and the demonstration of its antifungal applications. Schiff base was prepared from polyglucanaldehyde and chitosan, and the former was prepared by the oxidation of amylose (polyglucopyranose) isolated from abundantly available unutilized jackfruit seed starch.

The supramolecular assembly of stimuli-responsive gels is renowned in organic, polymeric and biological systems, but it is seldom reported in inorganic gel systems. Here we report the inorganic system alumino-siloxane (ALS) aquagel by sol-gel synthesis that shows a unique mechano-responsive property with an impressive recovery rate. An assembly of 2D nanoribbon/tape like structural architectures was distinctively identified as the primary building block of the aquagel structure.
