A High-Efficiency Electrochemical Biosensor for the Detection of Mucosal-Associated Invariant T Cells.

Mucosal-associated invariant T (MAIT) cells exhibit significant potential in the assessment of tumor development and immunotherapy. However, there is currently no convenient and efficient method to analyze the quantitative changes of MAIT cells during cancer development and treatment, which has not been extensively studied. Here, we report an electrochemical biosensor designed to efficiently monitor MAIT cells in peripheral blood by simultaneously recognizing Vα7.

Detection of glucose transporter 1 in living cells for assessment of tumor development and therapy using an electrochemical biosensor.

The expression level of glucose transporter 1 (GLUT-1) is highly correlated with tumor malignancy, making it a promising therapeutic target for cancer treatment. The detection of GLUT-1 expression level is significant for cancer discovery and valuating the efficacy of drug treatments. However, current methods for GLUT-1 detection primarily rely on traditional techniques.

Research progress of biosensors for detection of SARS-CoV-2 variants based on ACE2.

Currently, the coronavirus disease 2019 (COVID-19) pandemic is ravaging the world, causing serious crisis in economy and human health. The top priority is the detection and drug development of the novel coronavirus. The gold standard for real-time diagnosis of coronavirus disease is the reverse transcription-polymerase chain reaction (RT-PCR), which is usually operatively complex and time-consuming.
