Demystifying nano-neuro interactions

Nanomaterials already play a vital role in enhancing the performance of everyday products from electronics to cosmetics to food packaging. But, beyond their usefulness in making images sharper and products more stable, researchers in the McKelvey School of Engineering at Washington University in St. Louis have shown nanoparticles may also be an essential tool in […]

Water quality monitor, locust-inspired electronic nose under development

Two teams of engineers led by faculty in the McKelvey School of Engineering at Washington University in St. Louis will work toward developing products to monitor drinking water quality and to detect explosives with an electronic nose with one-year, $650,000 Convergence Accelerator Phase 1 grants from the National Science Foundation (NSF). Barani Raman, PhD, professor […]

Locusts’ sense of smell boosted with custom-made nanoparticles

Our sensory systems are highly adaptable. A person who cannot see after turning off a light in the night slowly achieves superior power to see even small objects. Women often attain a heightened sense of smell during pregnancy. How can the same sensory system that was underperforming can also exceed the expectation based on its […]

Engineers to build cyborg locusts, study odor-guided navigation

The inviting smell of a freshly baked cookie immediately triggers a motor response to search for the source of that smell. Often the cookie can be easily found. This everyday event that we perform without a thought is an amazing feat that combines our superior ability to smell the cookie and computational prowess to determine […]

Singamaneni to develop advanced protein imaging method

Cell-secreted proteins, such as antibodies, hormones and neurotransmitters, play a crucial role in maintaining overall health and well-being. They are also key components in disease research and in developing diagnostic tools and personalized medicines. However, current methods for studying these proteins are limited to observing large groups of cells together, which makes it difficult to […]

Brighter fluorescent markers allow for finer imaging of nanoscopic objects

Researchers at the McKelvey School of Engineering at Washington University in St. Louis have pioneered a new technique that will enable higher-resolution imaging of very small objects like neurons. The technique, which improves on an existing method called expansion microscopy, is described in a new paper published in the journal Nano Letters. Srikanth Singamaneni, PhD and Barani […]

Singamaneni named Hughes Professor

Srikanth Singamaneni, PhD, an internationally renowned materials scientist, has been named the Lilyan and E. Lisle Hughes Professor in the McKelvey School of Engineering at Washington University in St. Louis. Since he joined the department in 2010 as an assistant professor, Singamaneni has received nearly $10 million in funding for his research from numerous federal […]

Four Washington University faculty named AIMBE Fellows

Four Washington University in St. Louis faculty members have been named Fellows of the American Institute for Medical and Biological Engineering (AIMBE), joining 20 existing Fellows at Washington University. They are among 140 engineers inducted March 27 in Washington. AIMBE’s College of Fellows is limited to the top 2% of medical and biological engineers and […]

Connective issue: AI learns by doing more with less

Brains have evolved to do more with less. Take a tiny insect brain, which has less than a million neurons but shows a diversity of behaviors and is more energy efficient than current AI systems. These tiny brains serve as models for computing systems that are becoming more sophisticated as billions of silicon neurons can […]

No more needles?

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 […]

Researchers one step closer to bomb-sniffing cyborg locusts

If you want to enhance a locust to be used as a bomb-sniffing bug, there are a few technical challenges that need solving before sending it into the field. Is there some way to direct the locust — to tell it where to go to do its sniffing? And because the locusts can’t speak (yet), […]
