Most of the rapid detection of human pathogen viruses has been developed by using biosensor technology. The detection layer of the biosensor consists of short single-stranded DNA (probe) able to form a duplex with a complementary target nucleic acid fragment with high efficiency and specificity. The probe is associated with a transducer that translates the hybridization event into a physically measurable value based on electrochemical methods. Electrochemical DNA biosensors offer merits such as rapid response, portability, high sensitivity, ease of use, and low detection limit. This review provides an overview of label-based and label-free electrochemical DNA biosensors for the detection of viruses as well as their application in the past four years.","PeriodicalId":36938,"journal":{"name":"Current Topics in Electrochemistry","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41974182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The beneficial influence of adding fluoroethylene carbonate (FEC), thus enabling AN compatibility with graphite anodes, in different ratios to AN-based electrolytes represents the main focus of this manuscript. Long-term cycling measurements at 0 °C and 20 °C as well as conductivity and electrochemical stability measurements were performed to identify the optimal AN:FEC ratio. The electrochemical performance as well as the decomposition products were further investigated in graphite/lithium iron phosphate (LFP) cells to validate the applicability in lithium-ion cells.","PeriodicalId":36938,"journal":{"name":"Current Topics in Electrochemistry","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42432356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plasma nanocoatings with thicknesses of 20-30 nm were deposited onto 316L stainless steel coupons in a glow discharge of trimethylsilane (TMS) or its mixture with oxygen gas under various gas ratios. The surface chemistries of the plasma nanocoatings were characterized using Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). Corrosion properties of the plasma nanocoated 316L stainless steel coupons were assessed using potentiodynamic polarization, cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS) in phosphate-buffered saline (PBS) electrolytes that contain bovine serum albumin (BSA) or lysozyme. It was found that BSA adsorption on the plasma nanocoated 316L coupons was heavily favored. BSA adsorption on the plasma nanocoating surfaces could block charge-transfer reactions between the electrolyte and 316L substrate, and thus stabilize the 316L substrates from further corrosion. In contrast, lysozyme adsorption on the plasma nanocoated specimens was not as pronounced and mildly influenced the corrosion properties of the plasma nanocoated 316L stainless steel.</p>","PeriodicalId":36938,"journal":{"name":"Current Topics in Electrochemistry","volume":"19 ","pages":"1-15"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5799882/pdf/nihms918802.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35811821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
