Preparation and Application of Microdroplet Array

In recent years, microdroplet arrays have been widely used in biology, chemistry, materials science, and engineering, and droplet generation methods are becoming more effective and controllable. At the same time, droplet arrays have been widely studied for various applications due to their novel optical and electronic properties. In this mini review, Firstly, the principles of wetting and evaporation during the preparation of the droplet array are introduced. Secondly the hydrophilic and hydrophobic treatment methods for the preparation of the droplet array are discussed. Finally, the application of droplet arrays in different fields is summarized.
