Research progress and future prospects in glucose oxidase-like activity of Au NPs

With the advancement of scientific research, an increasing number of studies on metal nanozymes, particularly Au NPs, have been conducted. They possess glucose oxidase (GOD)-like activity and peroxidase (POD)-like activity, with GOD-like activity receiving the most attention. However, there is a lack of research and summary on future trends in Au NPs in biomedical field. Therefore, we conducted a study on the GOD-like activity of Au NPs based on 158 relevant publications downloaded from the Web of Science Core Collection between 2007 and 2023, using citation metrics, authors, nations, institutions, cited references, and keywords. We found that Au NPs were initially utilized for glucose biosensors, glucose detection in human serum, and the detection of other carbohydrates and proteins. Researchers have recently focused on its application in oncotherapy and diabetic wound treatment. In addition to being utilized to treat autoimmune illnesses, inflammation, and other diseases, Au NPs may eventually replace insulin and antibiotics. We anticipate that the use of Au NPs will increase in the future. We hope this study will serve as a guide for future researchers so that Au NPs can be applied more broadly and competently.
