In flexible electronics, biosensors, and new energy devices, screen printing technology is widely used due to its low cost and scalability. One of the key parameters determining the performance of these printed electrodes is a seemingly unfamiliar term: sheet resistance (方阻). 1.What is Sheet Resistance? Sheet resistance, measured in Ω/□ (ohms per square), describes the … Read more

Biosensors are analytical tools that combine the specific recognition capabilities of biological recognition elements (such as enzymes, antibodies, nucleic acids, cells, etc.) with physical or chemical signal conversion technologies to detect target substances (such as molecules, cells, pathogens, etc.). The core principle is to convert biochemical signals into quantifiable electrical signals, optical signals, thermal signals, … Read more
01 Dry Chemical Analysis Technology Dry chemical technology is compared to traditional wet chemical technology, where the liquid present in the sample serves as the reaction medium. The components to be measured react directly with dry reagents fixed on a carrier, allowing for qualitative observation or instrument detection (semi-quantitative) for chemical analysis. Single-layer Test Paper … Read more
