Abstract
The properties of Hemoglobin adsorbed on the silver colloid surface we re investigated by using surface enhanced Raman spectroscopy (SERS) in the determination of oxygen-hemoglobin, deoxygen-hemoglobin and heme. The results show that the heme chromophore of oxygen-hemoglobin inter acts directly with silver colloid, as a result of either its detachmen t from the protein matrix or denaturation from the protein. The deoxyg en-hemoglobin would not release its heme at the silver colloid as norm ally expected.
