Label-free and rapid analysis of a large-scale cells is essential for single-cell analysis and the point-of-care testing (POCT). We demonstrated a microchip-based impedance flow cytometer for cell identification and counting in single-cell level without labelling. Cells were focused to sequentially flow through a straight channel in a disposable chip. One pair of coplanar sensing electrodes underneath...
As a convenient, un-injurious and low cost method for women breast tumor diagnosis, Electrical Impedance Scanning (EIS) is being paid increasing attention. But EIS still has some problems. In theory the malignant tumor has higher electrical conductivity than normal tissue and benign tumor, so the cancer will be recognized in the EIS image as a bright spot. However, in practical the difference is not...
A pocket blood sugar apparatus tested by enzyme electrode, which was designed using carbon and silver plasma as conducting materials. Both the work and reference electrodes are applied to the parts of enzyme electrode. The glucose oxidase is taken as the medium of blood sugar measuring. And the range of measuring glucose is about 50mg/dL - 500mgl/dL. It has better linear for the results and fit coefficient...
