The neurotoxicity of nanoparticles: A bibliometric analysis

Abstract

The aim of this study was to evaluate the global scientific output of neurotoxicity of nanoparticles (NPs) and explore their hot spots and research trends. Articles about the neurotoxicity of NPs between 2008 and 2017 were taken from the Web of Science Core Collection database. The VOSviewer was used to analyze annual publications, countries/institutions, funding agencies, research objects, major journals, and international cooperation. The reference co-citation map and keywords were used to analyze the mechanisms of neurotoxicity of NPs. Six hundred and forty-one eligible studies were included for analysis, and the annual publications increased with time in the past decade. Based on the bibliometric analysis, China and the United States were the main countries in this field. Metals and metal oxides were the main types of NPs. Cell, rat, and mouse were the primary research objects of NPs. The main research hot spots might focus on the pathogenesis of NPs, such as oxidative stress and apoptosis. This study will help researchers understand the research status, hot spots, and trends of neurotoxicity of NPs.

Global research trends on bioflocculant potentials in wastewater remediation from 1990 to 2019 using a bibliometric approach

“…S1). Based on the source of the article's funding, we speculated that the Chinese government fully supported the research in this field (Su et al 2018).…”

“…2b. Keywords could summarize the focus of these articles and determine certain trends of the research based on analysing the keywords (Su et al 2018). Keywords are the essence of academic papers (Jones and Jackson 1970).…”

“…Using Web of Science Core Collection as mentioned in the original paper (Su et al, 2018), TS ¼ ((NPs* OR Nanomaterial* OR Nanocrystals* OR nano*) AND (Neurotoxicity* OR Poisoning, Nervous System*)) resulted in the database that includes 807 documents from 2008 to 2017. These results show a huge difference from the results in the original paper (Su et al, 2018).…”

“…Emerging Sources Citation Index (ESCI) complements the highly selective indexes by providing earlier visibility for sources under evaluation as part of SCI-EXPANDED's, SSCI's, and A&HCI's rigorous journal selection process (http://wokinfo.com/products_tools/multidisci plinary/esci/). Web of Science Core Collection: Chemical Indexes as well as SSCI, A&HCI, CPCI-S, CPCI-SSH, BKCI-S, and BKCI-SSH are inappropriate for "The neurotoxicity of nanoparticles: A bibliometric analysis" (Su et al, 2018).…”

“…The data were derived from the SCI-EXPANDED in Clarivate Analytics Web of Science (updated on March 18, 2019). A total of 764 documents were found by TS ¼ ((NPs* OR Nanomaterial* OR Nanocrystals* OR nano*) AND (Neurotoxicity* OR Poisoning, Nervous System*)) from 2008 to 2017 (Su et al, 2018). However, the Web of Science Core Collection is not designed for bibliometric studies but for researchers to find literatures (Ho, 2018a(Ho, , 2018b.…”
