Краткое описание
The character of the interaction between ultrasmall gold nanoparticles and ozone is shown to be mainly governed by the particle structure. For borohydride sols of gold nanoparticles with sizes of ≈3 nm, which are characterized by metallic properties, this interaction is reduced to reversible adsorption of ozone on their surface. At the same time, ozone adsorption on “nonplasmon” Au particles that have a diameter of 2 nm and a very defective structure results in their irreversible structural rearrangement and transition to a metallic state, which is accompanied by the appearance of a surface plasmon resonance. The set of the results obtained shows that nanoparticles of borohydride gold sols are more efficient as possible hemosensors of ozone than are larger particles synthesized by the citrate method.
