Evaluation of pharmacokinetics and biocompatibility of p-FE (n = 3 mice/group). a Time course of blood concentration in 92 h. Fluorescence signal decreased from 77.31 to 9.91%, with a long blood circulation half-life time of ~16 h and corresponding fluorescence images of blood samples. b Biodistribution of main organs of p-FE-treated mice after 24 h post injection. c Body weight of p-FE-treated mice (n = 6 mice/ group) over a period of time of 23 days and the excretion behavior of p-FE. Error bars correspond to standard deviation
