Synthesis and characterization of p-FE. a Scheme of p-FE synthesis and chemical structures of FE and the PS-g-PEG polymer. b Absorption and emission spectra (excited by an 808 nm laser) of FE in toluene. c Dynamic light scattering (DLS) analysis of p-FE in PBS buffer. d Absorption and emission spectra (excited by an 808 nm laser) of p-FE in PBS buffer. e Photo of p-FE dispersed in PBS buffer. Mw of PS-g-PEG is around 23000 g moL−1
