TEM images of PEG-coated gold nanoparticles. Samples were negative stained with 1% phosphotungstic acid; thereafter, images were taken. Scale bars = 200, 20 nm. a, d Naked Gold nanoparticles (negative stained with 1% phosphotungstic acid; there is no white coated around the nanoparticles (uncoated PEG6000). b, e Gold nanoparticles coated PEG-6000 (negative stained with 1% phosphotungstic acid) black color gold nanoparticles—white color PEG6000 (negative stain). c, f Gold nanoparticles coated PEG-6000 + PDC4 − chlorambucil (negative stained with 1% phosphotungstic acid)
