A frost resistant, stable artificial spider web was made using flexible, adhesive functional-hydrogel fibers for sensing and perception.

A dual network hydrogel based on Schiff base bonding and electrostatic interaction was prepared. The hydrogel is non-toxic, self-healing and injectable. And it has great drug release control, adjusting release rate via SA at different pH levels.

An underwater stable, durable and substrate-independent gelatin composite hydrogel (GMP) coating is developed for biomedical application, showing good anti-microbial, lubrication properties and tunable drug release ability.
