The discovery of PCR opened a new area of biological research. The impact can be oberved not only by the great progress in the field of molecular biology, but also in may achievements in other related fields of science.Molecular biology techniques have been implemented successfully in biology,biotechnology,medical science,diagnostics, and so on. PCR amplification have been used to design the new laboratory devices and analyse amplified DNA fragments. And according to the nature and construction of DNA molecules and the potential computable methods,some studies have been conclucted conceming mimicing living systevms, as well as developing and constructing artificial nanodevices, such as biomolecular sensors and artifical cells.%PCR的发现为生物学的研究开辟了一个崭新的领域,在分子生物学及其相关的领域取得了巨大进步.分子的生物学技术已成功应用于生物学、生物科技、医学、诊断学等,利用PCR扩增技术设计新的实验方法和分析扩增的DNA片段,根据DNA分子的性质、结构和潜在性的可计算方法,研究模拟活生物,构造人工纳米装置,如生物分子感应器和人造细胞.
