Lead nanoenzyme is a kind of nanomaterial with enzyme like activity Compared with natural enzyme, nano enzyme has higher catalytic activity and stability, and has the advantages of low cost and easy preparation It is widely used in the fields of biosensor, biotherapy, environmental monitoring and protection However, how to prevent the aggregation of nano enzyme and further improve the activity and stability of nano enzyme is one of the current research bottlenecks Recently, Professor Zhu Chengzhou's research group of central China Normal University has made new progress in this field (chem Commun 2019, DOI: 10.1039 / c9cc04436a) According to the introduction of Professor Zhu Chengzhou, Dr Zhu Chengzhou is now a professor and doctoral supervisor of central China Normal University, a Humboldt scholar in Germany and a winner of the overseas high-level talent introduction program In 2018, clarivate Analytics "highly cited scientists" in the world In 2013, he received his doctorate from Changchun Institute of Applied Chemistry, Chinese Academy of Sciences From 2013 to 2018, he worked at Dresden University of technology and Washington State University respectively The main research direction is biological analysis and energy application research based on functional nanomaterials Up to now, he has published more than 160 academic papers in international famous academic journals and monographs such as chem Rev., chem SOC Rev., adv mater., angel Chem Int ed., with a total citation of more than 10000 times and an H-index of 52 Frontier research achievements: dopamine induced Au hydrogel nanometers are used to enhance bionic catalysis Professor Zhu Cheng of Huazhong Normal University has made a series of pioneering work in the design and synthesis of precious metal hydrogel related materials and in the field of energy and environmental monitoring applications (Chem Rev 2015, 115, 8896-8943; Adv Mater 2016, 28, 8779-8783; ACS Energy Lett 2018 , 39 , 2038-2044; NanoEnergy
