a The diameter distribution for laser ablated silver nanoparticles (La-silver nanoparticles) exhibits a unimodal distribution with an average 24 nm. The inset shows a representative TEM image for La silver nanoparticles. b The hydrodynamic diameter for BSA coated silver nanoparticles (BSA-silver nanoparticles) is different for different surface coatings. TEM images for BSA coated citrate coated silver nanoparticles (Citrate-silver nanoparticles) (c) and PVP coated silver nanoparticles (PVP-silver nanoparticles) (d) and La-silver nanoparticles (e) show that the coating is maximum for La silver nanoparticles in agreement with the hydrodynamic diameter. The scale bar for all the panels is 20 nm. (reproduced from ref. Podila et al. [67], by permission of American Institute of Physics)
