Imaging the CNE2 Cell Using Surface-Enhanced Raman Scattering

Jianghua Li


Surface enhanced Raman scattering (SERS) is attracted as early diagnosis technique on cancer for the fingerprint of Raman spectra unique to the chemical species. To test whether SERS can be used as Raman active molecules on NPC with gold nanoparticles (AuNPs), CNE2 cell line used as a model to measure the distributions of AuNPs in cell. The result shows that there is a characteristic peak at 1044cm-1 in SERS; and SERS images display the stronger and more homogeneous scattering properties at 1044cm-1 than the other bands. Thus, SERS with AuNPs active may has the potential for the early detection on NPC.
Keywords: SERS, RS, AuNPs, NPC, CNE2
