 He shared the 2010 Kavli Prize in Nanoscience for this work.Interface and colloid science had existed for nearly a century before they became associated with nanotechnology.The first observations and size measurements of nanoparticles had been made during the first decade of the 20th century by Richard Adolf Zsigmondy, winner of the 1925 Nobel Prize in Chemistry, who made a detailed study of gold sols and other nanomaterials with sizes down to 10 nm using an ultramicroscope which was capable of visualizing particles much smaller than the light wavelength.
