I. Introduction
In the recent years, there is a growing interest on analyzing chemical and biological samples in fast and reliable way [1]. Small amounts of those samples can be flown through microfluidic channels to reaction chambers or electrical sensors [2]. Due to the small amounts and the controlled flow of the samples in microfluidic channels [3], it is possible to have high sensitivity or resolution on the analysis [4]. Integration of microfluidic channels and electrical components together on a single chip is called Lab-on-Chip (LoC) concept, and it receives significant interest from the scientific community. Miniaturized, high throughput and low-cost LoC concepts are extensively in use for the chemical and biological sample analysis [5], [6].
