Abstract

We developed a new hybrid consisting of Ag nanoprisms, poly(N-isopropylacrylamide) (PNIPAm), and fluorophores via layer-by-layer assembly. The fluorescence intensity below the lower critical solution temperature (LCST) of PNIPAm was 6.4 times stronger than that above the LCST, meaning that the hybrids can function as nanosized highly thermoresponsive fluorescent sensors.
