Beschreibung
Zusammenfassung:	Microfluidic impedance based lab on chip is a sensor module to measure the impedance of a single biological cell flowing in channel of micrometer size. In the present invention, the enhancement in the channel cross-section 30 micron [h]×45 micron [w] leads to reduce the pressure drop significantly i.e., around 40 kPa at 100 microliter/min, which demands by cartridge based micro-pump for portable devices at Point of Care (PoC) location. Lab on chip of present invention is capable of withstanding 20 Vpp for several hours without degradation of electrodes and also capable to measure the particle with dimension down to 2 microns. Lab on chip of present invention was also used to count the platelet of the diluted blood samples without any pretreatment and comparable to the clinical lab report.
