Riboflavin phosphate (RFP) is a biocompatible and non-toxic natural photo-initiator. RFP has been used with UV irradiation to strengthen cornea in the ophthalmology. Here, the effects of RFP to collagen matrix was assessed with visible light instead of UV. After the treatment of RFP and irradiation visible light, FT-IR and SEM were utilized to characterize chemical and morphological change. Also, the tensile strength of the collagen matrix was measured with variable RFP concentration and irradiation time. The biocompatibility of the treatment of RFP was evaluated by cell proliferation.
