Dual-Mode Plasmonic Colorimetric/Photothermal Aptasensor for OTA: Based on a Mn²⁺-Powered DNA Walker for Mediating AuNB Growth

The sensitive and efficient detection of ochratoxin A (OTA) is critical for protecting agricultural ecosystems and public health. A dual-mode plasmonic colorimetric/photothermal aptasensor, based on a Mn²⁺-powered DNA walker for mediating gold nanobipyramid (AuNB) growth, is proposed for...
