| Popis: | Impedance spectroscopy is a common approach in assessing passive electrical properties of biological matter. However, several problems appear in microfluidic devices in connection with high sensitivity signal acquisition from small volume sensors. The developed compact analyzer provides fast impedance spectroscopy measurement from three sensors in direct and differential modes. Measurement deficiencies are minimized with optimized electronics, measurement method, signal processing and mechanical design of the analyzer. Proposed solutions are targeted to the creation of reliable point-of-care (POC) diagnostic and monitoring appliances including lab-on-a-chip type devices in next steps. |
