The growing demand for diagnostic tools with enhanced analytical characteristics in terms of sensitivity, selectivity, and low response time has encouraged researchers to conduct their research towards the development of point-of-care (POC) biosensors. POC diagnostic devices are powerful tools for the detection, diagnosis, and monitoring of diseases at their initial stages. Microfluidic cytometers based on the Coulter principle have recently shown a great potential for POC biosensors for medical diagnosis. One of the most important components in detecting cells by a Coulter counter is a micropore or sensing gate. Therefore, in this study, for counting and sizing the cells using the resistive...
