本文介绍了一种制备碳水化合物包覆金纳米颗粒的一般方法。这种方法的通用性已经通过在AuNPs表面包覆以下糖来证明：葡萄糖(单糖)；蔗糖、麦芽糖或乳糖(双糖)；棉子糖(三糖)；以及淀粉(多糖)。无毒的、水溶性的膦氨基酸P(CH2NHCH(CH3-)COOH)3，THPAL被用作该过程的还原剂。制备的糖包被AuNPs的大小分别为：30±8 nm(葡萄糖)、10±6 nm(蔗糖)、8±2 nm(麦芽糖)、3±1 nm(乳糖)、6±2 nm(棉子糖)和39±9 nm(淀粉)。
This letter describes a general method for the preparation of carbohydrate coated gold nanoparticles. The generality of this method has been demonstrated by surface coating AuNPs with the following sugars: glucose (monosaccharide); sucrose, maltose, or lactose (disaccharides); raffinose (trisaccharide); and starch (polysaccharide). The non-toxic, water-soluble phosphino aminoacid P(CH2NHCH(CH3-)COOH)3, THPAL, has been used as a reducing agent in this process. The sizes of sugar coated AuNPs that have been generated in this study are: 30 ± 8 nm (Glucose), 10 ± 6 nm (sucrose), 8 ± 2 nm (maltose), 3 ± 1 nm (lactose), 6 ± 2 nm (raffinose), and 39 ± 9 nm (starch).
