Nanozymes: Advanced Colorimetric Array Sensors for the Development of Environmental Analysis

Recently, residual pollutants in the environment have posed a serious threat to ecosystems. Therefore, it is crucial to establish effective environmental pollutant detection strategies. Nanozymes are widely favored in the field of sensing due to their enzyme-like activity, adjustable activity and high stability. Meanwhile, the design of sensors is increasingly emphasizing features such as ease operation and high-throughput recognition. Compared with traditional sensors, sensor arrays have become a research hotspot in sensor due to their advantages. At present, colorimetric sensor arrays constructed based on nanozymes have been widely studied. They overcome the limitations of traditional sensors and are gradually being applied to the precise detection of various environmental pollutants. In this work, we briefly discuss the characteristics of nanozymes, systematically reviews the principles and methods of sensor arrays based on nanozyme, and focuses on analyzing the practical application of sensor arrays. Finally, we put forward the current challenges and future development trends to promote the in-depth development of sensors. The array sensing method based on nanozymes construction has demonstrated significant application value and development potential in the field of environmental monitoring.
