Abstract In this presentation, the thermo/photo-tunable detection of mercury (II) ions by polymeric micelles based on thermo/light-responsive block copolymers will be discussed. Even though the thermo/light-induced disruption of micelles has many applications, such as drug deliveries in which the photocontrolled release of the encapsulated drugs is possible, it has been rarely studied for the sensing applications. To the best of our knowledge, the current work presented in talk is the first example of the thermo/light -triggered turn-on colorimetric detection of mercury (II) ions by light-responsive block copolymer micelles. No detection of mercury (II) ions was observed initially, but micellar disruption by light irradiation resulted in turn-on detection. The general strategy presented herein can potentially be used for the preparation of polymeric micelles capable of the thermo/light -induced tunable detection of various kinds of water-soluble analytes.
