BACKGROUND:Patch clamp technique has been developed for more than 40 years as the"gold standard"for the study of ion channels.However,the research content of scientific research institutions is relatively independent,and the existing research results are not systematically summarized,which leads to the phenomenon of high repeatability and weak innovation in the existing research.Therefore,it is urgent to make a comprehensive review of patch clamp technology to clarify the current research status,hot spots,and future development direction.OBJECTIVE:To summarize the research status and development trend of patch clamp technique in recent 10 years.METHODS:Publications on patch clamp technology from 2013 to 2023 were collected using the Web of Science core collection database.CiteSpace and VOSviewer software were used to quantify the number of publications and analyze the network of literature entries,including countries,institutions,journals,authors,keywords,highly cited literature,and co-cited references.RESULTS AND CONCLUSION:(1)In recent 10 years,the research in the field of patch clamp technology has gradually entered a stage of stable development.(2)China and the United States are the leading countries in this regard.The Chinese Academy of Sciences is an institution with core influence.Journal of Neuroscience is the main publication.Park,Won Sun team(Jeonbuk National University)and Chu,Li team(Hebei Key Laboratory of Chinese Medicine Research on Cardio-Cerebrovascular Disease)have made outstanding contributions in this field,but there is less collaboration and communication between the teams and no network cooperation model has been formed.(3)Patch clamp technology is mainly used in the electrophysiological characteristics of the nervous system and the pathological mechanism of the disease,which is the focus of researchers'continuous attention.(4)In the study of electrophysiological characteristics of cardiovascular system and its pathological mechanism,the electrophysiological characteristics of primary cardiomyocytes and induced pluripotent stem cell-derived cardiomyocytes and the pathological mechanism of atrial fibrillation,cardiotoxicity,sudden cardiac death,hypertension and other cardiovascular diseases have been the focus of research in recent years.(5)In the application of patch clamp technology combined with other biotechnology,it will be an important research direction to focus on the cross fusion with optogenetics,two-photon calcium imaging and other technologies.(6)In the research of drug screening and identification of therapeutic targets,especially the research of patch clamp technology and traditional Chinese medicine compound,it will become a great help in the future research of component traditional Chinese medicine.
