Abstract:

      Water environmental pollution is a serious problem in China. There is an urgent need to develop rapid detection methods for environmental pollutants in water. In recent years， paper-based microfluidic analytical devices （μPAD） have been rapidly developed in the field of environmental monitoring. It has advantages such as low cost， simple production， less reagent consumption and ease of carrying. It satisfied the standard of rapid on-site testing device “ASSURED” established by the World Health Organization （WHO）. Hence， in this paper， the research progress of μPAD in water environment detection is reviewed from following aspects. First， the paper-based materials improvement strategies for μPAD preparation are introduced， the μPAD preparation methods and strategies are discussed for enhancement of μPAD sensing performance， and the available applied methods of fluid motion control on μPAD are summarized. Then， the research progress of water environment rapid detection methods and corresponding sensor development principles based on μPAD are mainly introduced. Finally， the current limitations of μPAD are evaluated and the further research orientation of μPAD are prospected.
