Unmodified gold nanoparticles (GNPs) can be wrapped with long genomic single- and double-stranded DNA (ssDNA and dsDNA) molecules produced by asymmetric polymerase chain reaction (As-PCR). More importantly, the DNA-Au interaction can be utilized for colorimetric detection of a specific nucleic acid sequence in clinical samples.
未经修饰的金纳米粒子(GNPs)可以被不对称聚合酶链反应(As-PCR)产生的长基因组单链和双链 DNA(ssDNA 和 dsDNA)分子包裹。更重要的是,DNA-Au 相互作用可用于临床样本中特定核酸序列的比色检测。
