Abstract The high quality surface-enhanced Raman spectra（SERS）of ri-boflavin on silver colloids were observed with 1064nm excitation employingFourier Transform Raman spectroscopy，The detecting limit of good FT-SERS can reach 3．2×10^(-10)M on NaOH active colloids. riboflavin touched the Ag surface by the C（2）＝0 and C（4）＝0．
