Photograph (a), UV-Vis spectra (b), and TEM images (right panel) of PEG-g-PVA-capped GNPs prepared using various (polymer : Au) ratio (0.125, 0.25, 0.5, and 1 w/w% for vials, spectra or TEM images from 1 to 4, resp.). Particle size diameters in TEM images are , , , and  nm for images 1, 2, 3, and 4, respectively. Scale bar in all images = 200 nm.
