Description

In Situ Crosslinking Injectable Hydrogel (Click Chemistry System) is designed to form a stable hydrogel network directly at the site of injection through bio-orthogonal click chemistry reactions (e.g., thiol–ene or azide–alkyne reactions). The system is delivered as a low-viscosity precursor solution, enabling smooth injection, followed by rapid crosslinking under physiological conditions.

This approach enables precise localization of the material and minimizes material loss or diffusion. The chemistry is highly specific and occurs under mild conditions, making it suitable for encapsulation of cells, proteins, and therapeutic agents. Gelation kinetics, mechanical strength, and degradation behavior can be tuned through polymer composition and functional group density.
