title: [Fluorescense enhancing of 5, 10, 15, 20-tetraphenylporphyrin in complex with human serum albumin and gold nanorods].
abstract: Using absorption and fluorescence spectroscopy methods we obtained the results demonstrating alterations in spectral characteristics in supramolecular system composed of gold nanorods (AuNR) (10 x 38 nm) and complexes of human serum albumin (HSA) and 5, 10, 15, 20-tetraphenylporphyrin (TPP). TPP fluorescence (max = 636 and 658 nm) was found to enhance. The dependence of fluorescence enhancing in time was of nonlinear nature. Maximum TPP fluorescence enhancing value was as high as 16% and it was achieved in 7 min after mixing the components. Simultaneously with TPP fluorescence enhancing we observed a decrease in HAS own fluorescence (max = 340 nm) and optical density reduction in maximum of longitudinal localized plasmon band of AuNR (max = 752 nm).
