Liu’s ID2 team is interested in interdisciplinary research using nanotechnology, chemistry and biomedical engineering knowledge to address challenges in life science. Liu’s ID2 team is also focusing on transnational research with close end-user engagement by developing low-cost paper based point-of-care devices for precision diagnostics in health care, environment monitoring, food safety, and biosecurity. Liu’s ID2 team aims to “Creating tools to quantify our health” where we modify the bio-nano interfaces for in vivo diagnostic devices applicable in life science, bioimaging and biomaterials as well as more fundamental research on real-time in vivo chemical sensing and dynamic cellular response systems. Current research projects within Liu’s ID2 group include: * Smart biosensing technologies * Intelligent nanoparticles for precision theranostics * Microfluidic paper based point-of-care devices * Wearable and implantable in vivo devices
