| Research Abstract |
In this study, a single comb-like electrode was studied, which was formed by arranging a number of microelectrodes at a given spacing. A thorough examination of the shape factors of the electrode led to electrochemical detection of more trace amounts of substances. High sensitivity has been achieved by the electrode alone with a characteristic shape. The electrode has good utility because a wide variety of target substances can be detected and the detection can be performed with a relatively cheap measuring apparatus. This electrode is expected to be used as a powerful detector for microfluidic analysis devices possibly demanded in a field of clinical diagnosis in near future.
