Biophysical characterization of PLGA-PEG-AXT050 nanoparticles. A The PLGA-PEG-AXT050 nanoparticles have a hydrodynamic particle diameter of approximately 65-80 nm. B Hydrodynamic particle diameter increased slightly as the percentage of AXT050 peptide conjugation increased. C Particle zeta potential was determined to be approximately -20 mV, without AXT050 conjugation content significantly affecting the surface charge.
