Effective and rapid point-of-care (POC) diagnostics have the capability to revolutionize public healthcare in both developed and developing countries. POC testing can provide in vitro diagnostics and immediately actionable healthcare information at accident sites, in doctors’ offices, and in ambulances. Biosensing for point-of-care diagnostics is a research field that has seen growing interest since the first device for detecting glucose was developed.

We would like to take this opportunity to extend our appreciation to all of the researchers who have contributed to point-of-care diagnostics. We would like to highlight multiple research projects in this field that are not just limited to the topics below.
