9.1 Introduction

Modern analytical chemistry aims at simplification (“easy to implement or do”), automation (“electromechanically self-operation”), and miniaturization (“small scale” or “make to a very small scale”) [1–4]. Miniaturized analytical systems, micro-total analysis systems (μ-TAS) and “lab-on-a-chip,” are used to represent small-scale analytical processes. Miniaturization process implies not only decreases in scale but also that other forces and phenomena are present in microsize environments [5,6]. These processes require advanced materials ...
