Chemically converted graphene (CCG) was found to effectively quench the fluorescence emission of Cy3 dye 1 (the intensity is down to 1/38 of 1 alone) in aqueous solution, due to the formation of CCG-1 hybrid. After addition of certain amount of bovine serum albumin (BSA) into the above mentioned system, about 60 times of fluorescence enhancement was observed for the hybrid of CCG-1. This has been employed to discriminate BSA, and the fluorescence intensity was found to be proportional to the BSA added in a concentration range from 0 to 8?10 -6 M, the BSA detection limit was down to 5?10 -8 M.
