Abstract

Chemically converted graphene (CCG) was found to greatly enhance the fluorescence response of squaraine (SQ) dyes to bovine serum albumin (BSA). Addition of BSA to the SQ-CCG solution, where squaraine dyes absorbed on the CCG surface, raised the fluorescence intensity by as much as 80 fold.
