The Spectrum Properties of Type Ι Collagen Self-Assembly Film
Abstract:
The type I collagen was used to prepare self-assembly film, the UV-vis spectrophotometer and Fluorescence spectrophotometer were employed to characterize those self-assembly films. The Fe (NO3)3 and CuSO4 were used as the additive to investigate the effect of the type I collagen film. It was found that the character spectra of collagen solution and self-assembly film were different, the Fe (NO3)3 enhanced the 408nm fluorescence emission peak, and CuSO4 caused a new emission peak at 399nm. The changes in the fluorescence of films suggest that the metal salt could affect the type I collagen self-assembly.
