Nanoparticle PCR(NP-PCR) is a new method to optimize PCR amplification. Suitable amount of Au nanoparticles can improve specificity
sensitivity and extension rate of PCR. In this paper
we compare efficiency of purifying NP-PCR products with different methods. In addition
topographies of DNA products in NP-PCR were observed with atomic force microscope(AFM) . The results show that most of DNA products purified directly by routing method remain almost free due to less effect of nanoparticales. The yields decrease when the AuNPs were removed by high-speed centrifugation. A little amount of DNA subsided with AuNPs.
