Optical methods and MTT method are used to characterize the antiproliferation effect of antitumor drug9-aminoacridine (9AA) with and without silver nanoparticles.Intracellular surface enhanced Raman scattering(SERS) spectra and fluorescent spectra of 9AA indicate the form of 9AA adsorbed on the surfaceof silver nanoparticles.Although both silver nanoparticles and antitumor drug can inhibit the growth ofHela cells,silver nanoparticles can slow down the antiproliferation effect on Hela cells at low concentrationof antitumor drugs.Our experimental results suggest that silver nanoparticles may serve as slow-releasedrug carriers,which is important in antitumor drug delivery.
