A carbon nanotube (CNT)‐modified electrode was fabricated by dropping a dispersion of multi‐walled CNTs in water‐soluble and amphiphilic phospholipid polymer with both dispersing ability and anti‐biofouling property onto a Au electrode. A poly(2‐methacryloyloxyethyl phosphorylcholine‐co‐n‐butyl methacrylate) (PMB) composed from 50 mol% of 2‐methacryloxylethyl phosphorylcholine and 50 mol% of n‐butyl methacrylate (PMB50) was used as dispersing reagent for CNTs. The dispersion of water‐insoluble material by PMB50 and its antifouling effects in electrochemical analysis were investigated. The CNT‐modified electrode showed an anodic peak potential that was shifted negatively and an increase in the current value for the electrolytic oxidation of nicotinamide adenine dinucleotide. In addition, the charge on PMB50 did not inhibit the electrochemical reaction of the redox compounds K₃[Fe(CN)₆], [Ru(NH₃)₆]Cl₃, and hydroxymethylferrocene. Cyclic voltammetry of K₃[Fe(CN)₆] in 4 % bovine serum albumin (BSA) using a bare Au electrode, the anodic peak current was reduced to 47 % of that without BSA. In contrast, the antifouling effect of the PMB50‐coated electrode meant that the current was only reduced to 70 % of that without BSA.

用具有防污和分散特性的两亲性磷脂聚合物固定碳纳米管电极以进行电化学分析

通过将多壁碳纳米管在水溶性和两亲性磷脂聚合物中的分散体同时具有分散能力和抗生物结垢性能，将碳纳米管（CNT）改性的电极滴​​到Au电极上。由50 mol％的2-甲基丙烯酰氧基乙基磷酰胆碱和50 mol％的甲基丙烯酸正丁酯（PMB50）组成的聚（2-甲基丙烯酰氧基氧乙基磷酸胆碱-甲基丙烯酸正丁酯）（PMB）被用作CNT的分散剂。研究了PMB50对水不溶性物质的分散及其在电化学分析中的防污作用。碳纳米管修饰的电极显示出阳极峰电位负移，并且烟酰胺腺嘌呤二核苷酸的电解氧化电流值增加。此外，₃ [Fe（CN）₆ ]，[Ru（NH ₃）₆ ] Cl ₃和羟甲基二茂铁。使用裸金电极在4％牛血清白蛋白（BSA）中进行K ₃ [Fe（CN）₆ ]的循环伏安法，其阳极峰值电流降至没有BSA时的47％。相比之下，涂有PMB50的电极的防污效果意味着电流仅降低到没有BSA的电流的70％。
