Smartphone-based optical imaging and sensing devices are among the next-generation biosensors that have shown great potential to transform the field of point-of-care (POC) diagnostics. The constant improvement of optics, image sensor, and computational power of smartphone devices have placed a transformative microscopy and sensing tool in billions of users’ hands. Using these miniaturized devices, personal health can be accurately monitored outside the clinics or laboratories, which is especially useful to improve medical access in resource-limited settings. This talk will highlight our effort in creating advanced field-portable biosensor platforms based on smartphones, especially the improvement of detection sensitivity from single nanoparticle/virus detection to single DNA strand or single fluorophore imaging. By coupling with emerging molecular assay technologies such as CRISPR, promising applications ranging from POC diagnostics of human diseases to in-field detection of plant pathogens will also be illustrated.
