Abstract

We report a novel approach for the synthesis of silver nanoparticles (NPs) stabilized on polymer-wrapped carbon nanotubes (Ag@polymer/CNTs) for the non-enzymatic glucose sensing and antibacterial activity applications. Poly(styrene--maleic anhydride) (PSM) was functionalized with amino furan to obtain furan-modified poly(styrene--maleic anhydride) (PSMF), which was later grafted onto the surface of CNTs by Diels-Alder "click" reaction to afford a polymer/CNTs hybrid material. The photo-deposition technique was applied to immobilized small-sized (∼10 nm) AgNPs on the surface of the polymer/CNTs hybrid material using visible light irradiation. The resulting material, Ag@polymer/CNTs, showed promising electrocatalytic activity for the non-enzymatic glucose sensing and antibacterial activity in vitro assays toward , , and bacteria strains. Covalent-bonded polymer layer-bearing carboxylic pendent groups to the CNTs might be playing a pivot role in not only stabilizing AgNPs but also facile electron-transfer reaction, thus demonstrating better activity.

摘要

我们报道了一种合成稳定在聚合物包裹碳纳米管上的银纳米颗粒（Ag@聚合物/碳纳米管）的新方法，用于非酶葡萄糖传感和抗菌活性应用。聚（苯乙烯-马来酸酐）（PSM）用氨基呋喃进行功能化，以获得呋喃改性的聚（苯乙烯-马来酸酐）（PSMF），随后通过狄尔斯-阿尔德“点击”反应将其接枝到碳纳米管表面，得到聚合物/碳纳米管杂化材料。采用光沉积技术，利用可见光照射将小尺寸（约10纳米）的银纳米颗粒固定在聚合物/碳纳米管杂化材料表面。所得材料Ag@聚合物/碳纳米管在体外对 、 和 细菌菌株的非酶葡萄糖传感和抗菌活性方面表现出有前景的电催化活性。与碳纳米管共价键合的带有羧基侧基的聚合物层可能不仅在稳定银纳米颗粒方面，而且在促进电子转移反应中发挥关键作用，从而表现出更好的活性。
