Researchers are uncovering new worlds at the nanoscale. Discover how scientists today build invisible structures out of DNA, listen in on bacterial “conversations,” and design textiles at the nanoscale with real-world applications for all of us.


DNA Origami
Dr. Michael Hudoba, Associate Professor and Department Chair of Engineering at Otterbein University, is a mechanical engineer who specializes in folding DNA into tiny “nanomachines.” With this process, called DNA origami, he can program DNA to fold into nanoscale-sized tools and technologies.


Bacteria Sensing
Dr. Fatima AlZahra’a Alatraktchi, adjunct professor at Roskilde University and founder of PreDiagnose, speaks about her research in bacterial sensing. Her team combines nanotechnology with molecular biology to listen in on bacterial “conversations” and develop reliable diagnostic tools for doctors.


Nanotechnology and Textiles
Dr. Juan Hinestroza, the Rebecca Q Morgan Professor of Fiber Science & Apparel Design at Cornell University, combines nanotechnology with textile science. From solar-powered vests to mosquito-proof dresses, his research team builds advanced technologies that can be worn as clothing.


QED with Dr. B

QED with Dr. B, is a fun and informative science series, co-produced by WOSU Public Media and the Center for Science and Industry (COSI), that talks one-on-one with the scientists, engineers and innovators who are redefining how we interact with our world.

Watch the series online or on WOSU TV on Wednesdays at 7:30 p.m.
