Résumé
A simple, low-cost, and universal gold nanoparticle (AuNP) aggregation-induced photothermal biosensing platform has been developed for the first time and applied for the visual quantitative genetic detection using a common thermometer. By exploiting the photothermal effect of target-induced gold nanoparticle aggregation, visual quantitative biochemical analysis can be achieved by simply recording temperature signals using a common thermometer. Compared to conventional genetic testing methods, it is label- and amplification-free and can be completed in 40 min without the aid of any advanced analytical instruments.
