Malaria test as simple as putting on a bandage

HOUSTON - Testing for malaria could become as simple as putting on a bandage.
That's the idea behind a platform developed by Rice University engineers who introduced a microneedle patch for rapid diagnostic testing that does not require extracting blood.
The device detailed in the Nature journal Microsystems and Nanoengineering draws upon protein biomarkers contained in dermal interstitial fluid, what people generally recognize as the fluid inside blisters but surrounds all of the cells in skin.
This fluid contains a multitude of biomarkers for various diseases, such as malaria, which can be used for rapid testing. The disposable patches could be programmed to detect other diseases, potentially including COVID-19, said mechanical engineer Peter Lillehoj of Rice's Brown School of Engineering.
"In this paper, we focus on malaria detection because this project was funded by the Bill and Melinda Gates Foundation, and it's a big priority for them," said Lillehoj, who joined Rice in January as an associate professor of mechanical engineering. "But we can adapt this technology to detect other diseases for which biomarkers appear in interstitial fluid."
