The optical transparency and mechanical properties of hydrogels obtained from Bombyx mori silk fibroin (SF) means they have the potential to provide the ideal matrix to deliver photosensitisers in topical formulations. Rojas et al. report the preparation and characterization of porphyrin‐loaded SF hydrogels. Incorporation of the negatively charged porphyrin did not interfere with the gelation process, and the hydrogels generate singlet oxygen upon irradiation with red light more efficiently than aqueous solutions of porphyrin at equal concentrations.
