report here the first example of organic radical battery with DNA. Though there is a growing interest in DNA/cationic-lipid complexes as promising gene delivery vehicles, few efforts have been focused on the use of such complexes as advanced materials for organic optoelectronic applications. The present article describes how substitution of the sodium counter cation of DNA with cationic amphiphilic lipid(1-4)
我们在这里报告带有DNA的有机自由基电池的第一个例子。尽管对DNA /阳离子-脂质复合物作为有前途的基因递送载体的兴趣日益增长,但很少有努力集中在将这种复合物用作有机光电应用的先进材料。本文介绍了如何用阳离子两亲性脂质(1-4)取代DNA的钠抗衡阳离子,从而提供含有TEMPO自由基的新型DNA-脂质复合物,其中磷酸盐与脂质的实际摩尔比为1:0.84至1: 0.16。所有含TEMPO的DNA-脂质复合物均显示出可逆的两阶段充电/放电过程,其放电容量为40.5-60.0 A h kg(-1)。特别是,基于DNA-脂质(3)的细胞的容量达到60.0 A h kg(-1),
