最近,美国德克萨斯大学的Michael V.Mirkin等人使用了一种超微铂电极来观测高聚物薄膜(200nm)内部的氧化还原反应。这项研究是近代电化应用趋向於越来越小空间的一个典型实例。这方面其它的例子还有:宾夕法尼亚大学的Andrew G.Ewing等人在生物单细胞内部进行了测量;北卡罗林那大学的P.Mark Wightman等人观测了神经键神经传-质中的胞外分泌。Bard等人使用一种带有宽度只有 Recently, Michael V. Mirkin et al at the University of Texas used an ultra-platinum electrode to observe the redox reaction inside a polymer film (200 nm). This study is a typical example of the trend towards smaller and smaller spaces in modern electrochemical applications. Other examples in this regard are: Andrew G.Ewing of the University of Pennsylvania et al., Which measured cells inside a single cell; P. Mark Wightman of the University of North Carolina, observed the cells in the neurotransmitter- Exocrine. Bard et al. Used only one with a width of only
