Label-free and ultrasensitive electrochemical biosensor for the detection of EBV-related DNA based on AgDNCs@DNA/AgNCs nanocomposites and lambda exonuclease-assisted target recycling.
本研究开发了一种无标记、高效的电化学生物传感器,用于超灵敏检测EBV相关DNA。该策略将AgDNCs@DNA/AgNCs纳米复合材料与非经典λ外切酶(λ exo)辅助目标循环(LNTR)相结合。AgDNCs、DNA/AgNCs与探针DNA形成的pDNA-AgDNCs@DNA/AgNCs共轭物既可作为理想纳米载体,也可作为高效电化学标...
