采用湿化学法合成了糖辅助的稳定的单-和双-纳米粒子。不同糖的还原能力的适当操作直接依赖于证实吸收峰位置偏移的粒度。在本实验条件下，金、铂、银和钯的纳米粒子直径分别为1、3、10和20 nm。前体溶液的蒸发导致较小颗粒的合成。已经发现果糖是最适合于合成最小颗粒的糖，因此被用于进化含有类似于10 nm的颗粒的Au-核-Ag-壳。(c)2005 Elsevier B. V.保留所有权利。
Sugar assisted stable mono- and bimetallic nanoparticles were synthesized by wet chemical method following a general scheme. Proper manipulation of the reducing capabilities of different sugars has direct dependence on the particle size corroborating the shift of the absorbance peak positions. Under the experimental condition, the spherical nanoparticles were found to be similar to 1, 3, 10 and 20 nm in diameter for gold, platinum, silver and palladium, respectively. Evaporation of the precursor solutions, led to the synthesis of smaller particles. Fructose has been found to be the best suited sugar for the synthesis of smallest particles and hence exploited for the evolution of Au-core-Ag-shell containing particles of similar to 10 nm.
