Abstract
Human hemoglobin (2.2×10−4 M) detection has been demonstrated on AgO surface enhanced Raman scattering (SERS)-substrates. Hot spots that enable detection of hemoglobin using SERS are formed at the silver nanoclusters induced by the photo-activation of AgO under Raman excitation wavelength (633 nm). Higher enhancement is observed at integration time (20 s) and threshold energy density (12 M J/cm2). At higher excitation energy densities photo-chemical (or photo-thermal) activity of the hemoglobin molecules are dominated. These results are critical to the future use of AgO films as SERS substrates for the detection of biological molecules.
