DNA biosensor based detection for neglected tropical disease: moving towards smart diagnosis Sens. Rev. (IF 1.6) Pub Date : 2022-07-21 Bjorn John Stephen, Surabhi Suchanti, Devendra Jain, Harshdeep Dhaliwal, Vikram Sharma, Ramandeep Kaur, Rajeev Mishra, Abhijeet Singh
Purpose Neglected tropical diseases (NTDs) are a set of infectious diseases that primarily affect low-income countries situated near the equator. Effective diagnostic tools hold the key to stemming the spread of these infectious diseases. However, specificity is a major concern associated with current diagnostic protocols. In this regard, electrochemical deoxyribonucleic acid (DNA) biosensors could

Research on compensation method for registration error of large-scale measurement field based on multi-temperature sensors Sens. Rev. (IF 1.6) Pub Date : 2022-07-15 Lulu Huang, Xiang Huang, Shuang-Gao Li
Purpose The size of the aircraft tooling structure is huge, and the ambient temperature is difficult to maintain a constant state. Aiming at the influence of current temperature, this paper aims to propose a compensation method for registration error of large-scale measurement fields based on multi-temperature sensors. Design/methodology/approach In this method, an enhanced reference points (ERS)–temperature
