From Nano to Global: Bridging the
Gaps in Health Care

Biomedical engineer John T. McDevitt discusses his bio-nano-chip research and its application in bridging gaps in global health care (video link).

For about four decades, flow cytometer instruments have been the dominant approach for sophisticated cell typing applications as required for HIV immune function testing. Unfortunately, over two thirds of the global HIV-AIDS problem is restricted to resource-poor settings where flow cytometry can reach on a small portion of the inflicted population.

The McDevitt laboratory, through a partnership with LabNow, has created a portable cellular processing unit that when paired with a universal analyzer can be used to make the HIV immune function measurements at the point-of-need. This video shows the traditional flow cytometer instrument juxtaposed to the new medical micro-device (video link).

McDevitt Research Lab Demo

A compact, ruggedized illumination system suitable for high-performance cellular and protein measurements is shown. Through collaboration between the McDevitt laboratory and LabNow, these powerful image analysis tools are being created for use both in resource poor settings as well as in traditional health care locations (video link).

Peter Jennings and Gina Smith on ABC’s Nightly News feature a story on the “electronic tongue” developed by the McDevitt laboratory.

As this video highlights, the microchip sensor system had its origin in the complex testing of foods, beverages, and toxins. (video link).

The initial paper describing the micro-bead array sensor featured a complex vapor analysis using “electronic noses”. With this background in mind, the initial micro-bead array approach was naturally dubbed as the “electronic tongue”.

Interestingly, the public release of the electronic tongue terminology was picked up by several scientific and generic news agencies. Perhaps the most unusual coverage came form Jay Leno's opening monologue. Watch the movie and see how the work ended up in his monologue. Please note that the authors do not endorse these suggestions. Following this coverage, the new terminology of “electronic taste chip” was introduced into the literature (video link).
