[Targeted imaging ability of a biotinylated imaging probe Biotin-S-S-Rhodol for breast cancer cells in vitro].

Objective: To investigate performance of a biotinylated imaging probe 3a for targeted imaging of breast cancer cells.

Methods: Ultraviolet absorption spectrum and fluorescence spectrum were employed to analyze the spectral characteristics of 3a. The fluorescence spectrums of 3a treated with different concentrations of glutathione (GSH) were obtained to determine the sensibility of 3a to GSH.
