SERS Effect of Nucleic Acid Alkaline Groups on Argentine Piece Treated by ORC
经ORC处理银衬底上核酸碱基的SERS研究

SERS effect of argentine is calculated and analyzed b y use of Antenna Resonance Model.The results show that a maximum enhanced factor is greater than 140 at 1.38eV near infrared, factors are about 60,48 and 45 at 3.35 eV,3.90 eV and 4.30 eV near ultraviolet zone .It is predicted that a maximu m enhanced factor is 70 in visible light zone.SERS spectrum of adenine and uracil are got from argentine piece treated by ORC. Adenine has distinct SERS effect with the presence of fluorescence.Four specific peak values are of SERS spectrum of uracil which has a maximum model,SERS ring breathing model,of four,at 1035 c m -1 affording the foundation.
