Hydrogel

Hydrogel describes a three-dimensional network of hydrophilic polymers capable of absorbing large amounts of water while maintaining structural integrity, making it valuable for controlled drug delivery, tissue engineering, and wound care applications. Hydrogels can be engineered to respond to stimuli such as pH, temperature, or enzymatic activity, enabling targeted release profiles and improved local delivery.

The pharmaceutical industry develops hydrogel-based systems to improve delivery of drugs requiring sustained exposure, local administration, or protection from degradation. Injectable hydrogels enable minimally invasive delivery, forming depots that release therapeutics over extended periods while reducing dosing frequency. Regenerative medicine uses hydrogels as scaffolds supporting cell survival and tissue integration. Manufacturing and development require controlling polymer composition, crosslinking chemistry, degradation behaviour, and sterility assurance. As advanced delivery systems become more important for biologics and cell therapies, hydrogel technologies continue expanding as versatile platforms supporting innovative therapeutic strategies.
