Abstract
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(CH(2)NHCH(CH(3)-)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).
摘要
这封信描述了一种制备碳水化合物包覆金纳米颗粒的通用方法。通过用以下糖类包覆金纳米颗粒（AuNPs）证明了该方法的通用性：葡萄糖（单糖）；蔗糖、麦芽糖或乳糖（二糖）；棉子糖（三糖）；以及淀粉（多糖）。无毒的水溶性膦基氨基酸P(CH(2)NHCH(CH(3)-)COOH)(3)，即THPAL，在此过程中用作还原剂。本研究中生成的糖包覆金纳米颗粒的尺寸为：30±8纳米（葡萄糖）、10±6纳米（蔗糖）、8±2纳米（麦芽糖）、3±1纳米（乳糖）、6±2纳米（棉子糖）和39±9纳米（淀粉）。
