Probing and modulating the interactions of the DNAzyme with DNA-functionalized nanoparticles
文献摘要:
DNA-functionalized gold nanoparticles are one of the most versatile bionanomaterials for biomedical and clinical diagnosis.Herein,we discovered that the performance of DNAzyme cleaving the substrate is highly related to its length.This intriguing phenomenon only appears at the interfaces of DNA-functionalized gold nanoparticles.We systematically investigated the causes of this phenomenon.We conjectured that the DNAzyme with extended nucleotides that do not match its substrate strand is vul-nerable to non-specific adsorption,electrostatic repulsion,and steric hindrance.Based on our improved understanding of this phenomenon,we have successfully developed a highly sensitive and specific am-plifiable biosensor to detect human apurinic/apyrimidinic endonuclease 1.
