Characteristics of gold nanoparticles (AuNPs) using atomic force microscopy (AFM). (a) Representative height sensor image of AuNPs deposited on nonfunctionalized mica showing their diversity in size and lack of the tendency for particle agglomeration in water suspension. (b) Typical shape of a gold nanoparticle obtained in Peak Force mode at high-resolution imaging (the particle height equal to c. 9.5 nm). (c) A height profile of an individual AuNP used for determination of the particle size. (d) The distribution of nanoparticle size.
