Paper-Based Microfluidic Devices for Pesticide Detection

Abstract

The µ-PADs have been acknowledged as an efficient analytical platform to monitor and detect various contaminants present in the environment. Paper-based devices have always been a choice raw material for several technologies as they aid in developing biodegradable, cost-effective, and readily available units with easily driven and changeable flow rates, and the ability to store reagents. In comparison to conventional analytical systems such as capillary electrophoresis, high-performance liquid chromatography, and gas and liquid mass spectroscopy, the use of µ-PADs brings more significant results in pesticide detection. This chapter discussed the strategies that are commonly used to detect pesticides which are double-catalytic amplification, UV-induced fluorescence spectroscopy, ratiometric fluorescence imaging (based on wavelength intensities to detect variation in the native environment), electrochemical sensing, electrospray ionization, and competitive-inhibiting reaction.
