ABSTRACT
The fluorescent dye perylene-3,4,9,10-tetracarboxylic dianhydride (PBA) was immobilized onto polysulfone hollow fibers by means of a wet coating procedure. After immobilization, PBA was able to react with primary amines through a double anhydride ring opening reaction. The inâ
situ amine coupling was further revealed by fluorescence analysis. Both emission (534â
nmâ
â538â
nm) and fluorescence lifetime changes (2.7â
nsâ
â3.3â
ns) of the dye are a useful tool to detect and visualize the occurrence of the reaction. The successful implementation of amine coupling with a reporting function on polysulfone fibers holds great interest for biomedical applications.
