文摘

•: A novel nanosensor for selective detection of 2,4,6-trinitrotolune was fabricated.
•: A Meisenheimer complex was formed by means of a charge transfer process from AuNPs-NH₂ to TNT, which promotes the aggregation of AuNPs-NH₂, thus, enhance the photothermal performance.
•: The proposed sensor realized on-site visual and ultra-sensitive detection of TNT based on the induced photothermal effect.
