Zinc oxide (ZnO) is a unique semiconductor material with wide bandgap (3.37 eV) and high exciton binding energy (60 meV) at room temperature. ZnO nanostructures have been investigated extensively for possible use as high-performance sensors, due to their excellent optical, piezoelectric and electrochemical properties, as well as the large surface area. In this review, we primarily introduce the morphology and major synthetic methods of ZnO nanomaterials, with a brief discussion of the advantages and weaknesses of each method. Then, we mainly focus on the recent progress in ZnO nanosensors according to the functional classification, including pressure sensor, gas sensor, photoelectric sensor, biosensor and temperature sensor. We provide a comprehensive analysis of the research status and constraints for the development of ZnO nanosensor in each category. Finally, the challenges and future research directions of nanosensors based on ZnO are prospected and summarized. It is of profound significance to research ZnO nanosensors in depth, which will promote the development of artificial intelligence, medical and health, as well as industrial, production.<\/jats:p>","DOI":"10.3390\/s21165502","type":"journal-article","created":{"date-parts":[[2021,8,16]],"date-time":"2021-08-16T21:28:04Z","timestamp":1629149284000},"page":"5502","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":96,"title":["Progress in ZnO Nanosensors"],"prefix":"10.3390","volume":"21","author":[{"given":"Miaoling","family":"Que","sequence":"first","affiliation":[{"name":"College of Electronic and Information Engineering, Suzhou University of Science and Technology, Suzhou 215009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7519-9160","authenticated-orcid":false,"given":"Chong","family":"Lin","sequence":"additional","affiliation":[{"name":"Jiangxi Province Key Laboratory of Polymer Micro\/Nano Manufacturing and Devices, School of Chemistry, Biology and Materials Science, East China University of Technology, Nanchang 330013, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiawei","family":"Sun","sequence":"additional","affiliation":[{"name":"College of Electronic and Information Engineering, Suzhou University of Science and Technology, Suzhou 215009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lixiang","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Electronic and Information Engineering, Suzhou University of Science and Technology, Suzhou 215009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaohong","family":"Sun","sequence":"additional","affiliation":[{"name":"College of Electronic and Information Engineering, Suzhou University of Science and Technology, Suzhou 215009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yunfei","family":"Sun","sequence":"additional","affiliation":[{"name":"College of Electronic and Information Engineering, Suzhou University of Science and Technology, Suzhou 215009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Srinivasan, P., and Mehtre, S.
