Nanoparticle PCR： A New Approach of DNA Amplification

The polymerase chain reac- tion (PCR) is a technique for quickly “cloning” a par- ticular piece of DNA in the test tube (rather than in living cells like E. coli). Thanks to this procedure, one can make virtually unlimited copies of a single DNA molecule even though it is initially present in a mix- ture containing many different DNA molecules. In cooperation with research- ers from Shanghai Jiao Tong University, CAS scientists have come up with a novel approach to improve the specif…
