Engineering researchers have developed a new technique for eliminating particularly tough blood clots, using engineered nanodroplets and an ultrasound “drill” to break up the clots from the inside out. The technique has not yet gone through clinical testing. In vitro testing has shown promising results.
Specifically, the new approach is designed to treat retracted blood clots, which form over extended periods of time and are especially dense. These clots are particularly difficult to treat because they are less porous than other clots, making it hard for drugs that dissolve blood clots to penetrate into the clot… Continue reading.
Biomedical engineers at UNC-Chapel Hill and NC State respond to COVID-19 by teaming to speed the development of an emergency ventilator
Biomedical engineering student Kathlyne Bautista always knew that her coursework and training would set her on a path to make a life-changing difference for people. But before the coronavirus pandemic, she didn’t realize just how soon that opportunity would arrive.
Bautista is part of the Carolina Respiratory Emergency – Ventilator (CaRE-Vent) team led by Dr. Yueh Lee, MD, an associate professor at the University of North Carolina at Chapel Hill. His research team is sprinting to design and prototype an open-source ventilator in a matter of weeks that has the potential to help fill a critical equipment gap caused by a projected spike in COVID-19 patients. The group is designing the ventilator so that it could be manufactured quickly and inexpensively – at less than $1,000 and with only six hours of skilled labor per unit.
And even in the best-case scenario – where the COVID-19 curve flattens to the point that the device is never needed for patients – the team’s efforts are advancing knowledge in the biomedical design community about the best way to create emergency ventilators in the future… Continue reading.
This week the Office of the Executive Vice Chancellor and Provost announced that BME Professor Paul Dayton is receiving a W.R. Kenan, Jr. Distinguished Professor appointment. Professor Dayton, a biomedical ultrasound engineer, is also Associate Chair at the UNC/ NCSU Joint Department of Biomedical Engineering. Moreover, he is Professor in the UNC Eshelman School of Pharmacy and an Adjunct Professor of Radiology. Dr. Dayton is widely published and cited for his innovative work using ultrasound and microbubble contrast agents for biomedical applications… Continue reading.
A new ultrasound technique provides a non-invasive way of assessing bone structure on the microscale. Researchers hope to fine-tune the technique for use in assessing osteoporosis risk and treatment.
Researchers have also demonstrated that a variation of the same technique can distinguish between tumors and healthy tissue in a study using laboratory rats… Continue reading.
WASHINGTON, D.C.—The American Institute for Medical and Biological Engineering (AIMBE) has announced the induction of Paul A. Dayton, Ph.D., Professor, Joint Department of Biomedical Engineering, University of North Carolina at Chapel Hill, to its College of Fellows. Dr. Dayton was nominated, reviewed, and elected by peers and members of the College of Fellows for outstanding contributions to biomedical engineering in the areas of contrast-enhanced ultrasound imaging and ultrasound-targeted therapeutics.
