Novel Multibiosensors and Biomedical Application

Abstract

Annually, a lot of patients in Canadian hospitals are contaminated with antibiotic-resistant bacteria, resulting in abundant amounts of money spent on the health-care system. Even though most bacteria are risk-free to healthy individuals, the symptoms of bacterial contamination can be severe for patients with a weakened immune system. Early detection is critical for improved patient care and can help in minimizing the risk of cross contamination between patients. This work aims at using state-of-the-art technologies for developing handheld multibiosensors on a single chip for pathogenic bacteria detection. There is extensive demand for a low-cost, rapid, selective and sensitive method for detecting bacteria in medical diagnosis, and food-safety inspection. In this work, we are introducing more than one technique based on a CMOS/MEMS technology batch process for detecting pathogen bacterial cell at a low concentration level. The methodology of the proposed multi-labs-on-a-single-chip system (MLoC) lies on miniaturizing transducers, which is utilizing a sort of technique that has the capability to smooth the progress of point-of-care testing (POCT) and become conscious state-of-the-art molecular analysis independently of the state-of-the-art laboratory. MLoC methodology can be categorized as electrochemical, capacitive and optical, on the light of their sensing theory, incorporated with interdigitated microelectrode array (IDMA).
