Abstract
This work is dedicated to investigation of influence of different values of pH on binding of nanomarkers of fluorescein family (fluorescein, erythrosin, eosin and Bengal rose) to bovine serum albumin (BSA). For this purpose dependences of nanomarkers fluorescence, of nanomarkers molecular association, of types of chemical bonds between BSA and nanomarkers on pH are detected. The red shift of fluorescence spectra and the quenching of fluorescence of nanomarkers of fluorescein family in BSA solutions are observed. The decrease of degree of molecular association of nanomarkers in BSA solutions is found out. The dependences of fluorescence intensity and dependences of degree of molecular association on pH of halogen-derivatives of fluorescein differ dramatically from that of fluorescein.
