Special Seminar: Mobile Phone Based Imaging, Sensing, and Diagnostic Tools—New Horizons for Global Health, Telemedicine, and Point-of-Care Detection

Qingshan Wei, Postdoctoral Scholar, Depts of Electrical and Bio-engineering, UCLA

Zaleski Auditorium (Room B01), MacLean ESC


Diagnostics play critical roles in health care. However, conventional diagnostic systems do not address the needs of the majority of the world’s population who are afflicted by major human diseases as a result of lacking the access to affordable medical care. This talk focuses on mobile phone based imaging, sensing and diagnostics technologies, which provide cost-effective and field-portable solutions to various telemedicine and point-of-care diagnostic applications, aiming to transform future practices of medicine in resource-limited or remote settings. First, I will introduce my recent work on the development of handheld mobile phone based fluorescence microscopy platforms for imaging of single nanoparticles and viruses. I will detail our results on using the same mobile microscopy platform for imaging and sizing of single DNA molecules. Second, I will demonstrate a simple and sensitive smartphone-based molecular sensing device for detection and mapping of mercury contaminations in water spatiotemporally. Beyond the direct relevance for global health, the results also suggest tremendous new opportunities for fundamental nanoscience and technology. 

About the Speaker
