Nanoparticle physiochemical properties. a) Fourier Transform Infrared (FTIR) of uncoated nanoparticles, chitosan-PEG-coated nanoparticles (NP), and biotinylated-NP binding SA (NPB-SA). b) Fluorescence analysis showing that biotinylated nanoparticles (NPB-AF647) enhanced binding to the avidin of the biotective agent, compared with control nanoparticles (i.e. NP and NP-AF647). c) Hydrodynamic sizes of nanoparticles with and without fluorophores or biotin. d) Zeta potentials of nanoparticles with and without biotin.
