Abstract
Reversible formation and dissolution of gold nanoparticles through turning on and off UV light was reported. Gold ions (Au(3+)) were reduced to monodispersed gold nanoparticles by UV irradiation from a mixture of comb-like poly(oxyethylene)s and a gold salt. The prepared gold nanoparticles dissolved to yield gold ions (Au(3+)) when the UV light was switched off. Such formation and dissolution could be repeated persistently by turning the UV light on and off repeatedly.Entities:
