Figure 2: Characterization of nanoparticles (a) The molecular weight distribution of poly(AMPD-BAC) and poly(AMPD-BAC) in the incubation with 10 mM GSH. (b) Particle size of nanoparticle as monitored by DLS. poly(AMPD-BAC)-g-PEG, poly(AMPD-BAC)-g-PEG-DTPA-Pt. The incorporation of the DTPA-Pt has effect on nanoparticle size, in which poly(AMPD-BAC)-g-PEG-DTPA-Pt forms nanoparticle (117.68 nm) with an increase in size of poly(AMPDBAC)- g-PEG (92 nm). TEM image of (c) poly(AMPD-BAC)-g-PEG, (d) poly(AMPD-BAC)-g-PEG-DTPA, (e) poly(AMPD-BAC)-g-PEG-DTPA- Pt. (f) Schematics representation of poly(AMPD-BAC)-g-PEG-DTPA after incorporation of Pt.
