Grant funds research pushing limits of cyborg insects

The Office of Naval Research has awarded Barani Raman, professor of biomedical engineering at the McKelvey School of Engineering at Washington University in St. Louis, an $851,320 grant for research to determine just how sensitive locusts’ noses are when it comes to explosives – and how well researchers can interpret what the insects are sensing.

The research – which includes Srikanth Singamaneni, the Lilyan & E. Lisle Hughes Professor of mechanical engineering and materials science, and Shantanu Chakrabartty, the Clifford W. Murphy Professor of electrical and systems engineering – will be partially conducted on campus and partially at a naval facility.
Novel Microneedle Patch on the Skin Can Test for Biomarkers
A team at the McKelvey School of Engineering at Washington University in St. Louis have developed a microneedle patch that can be applied to the skin, capture a biomarker of interest from interstitial fluid and, thanks to its unprecedented sensitivity, allow clinicians to detect its presence.

Blood draws are no fun.
They hurt. Veins can burst, or even roll like they’re trying to avoid the needle, too.
Oftentimes, doctors use blood samples to check for biomarkers of disease: antibodies that signal a viral or bacterial infection, such as SARS-CoV-2, the virus responsible for COVID-19, or cytokines indicative of inflammation seen in conditions such as rheumatoid arthritis and sepsis.
