Abstract :
In this paper, Raman spectra of hepatocellular carcinoma cells were analyzed using gold and silver nanoparticles as SERS active substrates. The size of gold and silver nanoparticles is about 50-60 nm, and these nanoparticles have enhancement role to the Raman spectrum of hepatocellular carcinoma cells. The results show that the Raman enhancement effects of gold colloid are more sensitive than silver colloid to cells.
