Temperature-sensitive carbon dots derived from poly(N-isopropylacrylamide) for fluorescence on–off properties

Abstract

Here, we report novel thermo-responsive fluorescent nanoparticles of carbonized poly(<italic>N</italic>-isopropylacrylamide) (PNIPAAm) through carbonization. The partial carbonized PNIPAAm (F-PNIPAAm) shows reversible capability based on fluorescence intensity.
