Characterization of OvCa cell specific PBM NPs. Fis- and PTX-encapsulated, FA-conjugated, and PCL-PEG copolymer-coated and uncoated NPs were characterized based on their [A] size and [B] zeta potential. NMR was conducted to determine the appropriate conjugation of [C] Fis-FA-PBM-NPs and [D] PTX-FA-PBM NPs, as shown in the 1 H NMR spectra. The arrows indicate peaks in ppm for starch, FA, PEG, polycaprolactone (PCL), Fis, and PTX. A Bruker 400 MHz Spectrometer was used to record the spectra
