Surface-enhanced Raman scattering(SERS) spectroscopy was employed to analyze the genotoxic nucleobase adducts of benzo[a]pyrene(BP) formed through one-electron oxidation pathway. SERS spectroscopy provided sufficient resolution to distinguish if BP intermediate was bound to different nucleobases(e. g. adenine or guanine). Furthermore, SERS specroscopy was also able to detect the difference in the binding position of the adduct to the various sites of the nucleobase. The linearity of the calibration curve for N7Ade-BP ranged from 20 picogram to 800 nanogram per microliter and the detection limit under the current conditions was determined 20 picogram per microliter in a solution volume of 20 microliter.
표면강화 라만분광학을 이용하여 단일전자 산화반응으로 형성된 발암성 벤조피렌 유도체가 nucleobase와 반응하여 생성된 첨가 생성물을 분석하였다. 표면강화 라만분광학을 이용하여 아데닌 또는 구아닌과 같이 각기 다른 종류의 nucleobase와 결합하여 형성된 첨가생성물을 구분하여 분석할 수 있었고 또한 nucleobase 분자의 다른 부분에 결합하여 형성된 이성길체를 라만분광스펙트럼을 통하여 구분하여 분석이 가능하였다. N7Ade-BP에 대한 검정곡선의 선형도 범위는 20 picogram/
