摘要
The capabilities of using gold nanoparticle as surface-enhanced Raman scattering (SERS) substrate to obtain cervical smear harvested cells biochemical information for non-invasive cervical precancerous detection were presented in this patent document. A SERS reagent and a platform has been developed and optimized for the generation of a differential spectral fingerprinting for cervical cancer detection. SERS measurements were performed on three group's cervical exfoliated cell samples: one group from patients (n=36) with pathologically confirmed cervical cancer and another group with high-grade squamous intraepithelial lesion (HSIL) (n=41) and the last group from healthy volunteers (control subjects, n=47). Tentative assignments of the Raman bands in the measured SERS spectra suggested interesting cancer specific biomolecular changes, including an increase in the relative amounts of amino acids, nucleic acid, carotenoid contents in the cell samples of cervical cancer patients as compared to that of healthy subjects. The results from this study demonstrated that gold nanoparticle based SERS substrate harvested exfoliated cervical smear cell analysis has tremendous potential for the non-invasive detection of cervical precancerous lesions.
