Integrating multiple hybridization chain reactions on gold nanoparticle and alkaline phosphatase-mediated in situ growth of gold nanobipyramids: An ultrasensitive and high color resolution colorimetric method to detect the mecA gene of Staphylococcus aureus.

比色法是一种有潜力的无仪器即时基因组检测平台，但常受限于灵敏度低和颜色分辨率差。本文报道了一种高分辨率比色生物传感器，用于超灵敏检测金黄色葡萄球菌（Staphylococcus aureus）mecA 基因。该传感器基于金纳米颗粒（AuNP）上的多重杂交链反应（HCR）和碱性磷酸酶（ALP）介导的金纳米双锥（AuNBPs）原位生长。...
