Biomimetic hydrogel with photodynamic antimicrobial effect
(PHYSorg.com Chemistry)

Infections are a dreaded threat that can have fatal consequences after an operation, in the treatment of wounds, and during tissue engineering. Biomimetic hydrogels with `built-in` antimicrobial properties can significantly decrease this danger. In the journal Angewandte Chemie, scientists have now introduced a gel that is activated by red light to produce reactive oxygen compounds that effectively kill bacteria and fungi.
