Development of low-cost rapid pathogen detection microsystem in COVID-19 Pandemic: Electronic Engineering Approach
Project Description

Due to the massive outbreak of Coronavirus-19 worldwide, rapid and accurate detection of pathogenic microorganisms has become a top priority. Compared to the current centralized detection mode, miniaturized detection platforms could enable real-time and on-spot testing of diseases, which could reduce the unnecessary pressure on medical system and avoid the possible contamination of samples during shipment. Our research team wants to integrate the CMOS ion-sensitive field-effect transistors (ISFETs) with microfluidics to propose a rapid electrochemical detection system for COVID-19. The microfluidics will take part of DNA extraction from samples and the on-chip PCR while the ISFETs will be used to detect the pH change during the amplification process. Subsequently, the system can also be used to establish an IoT platform for more convenient and effective data management by integrating Bluetooth modules with the cloud for wireless data transfer.
