Vanderbilt engineer develops tiny tweezers to trap nanoscale molecules as small as proteins

Aug. 31, 2020—An assistant professor of electrical engineering has developed the first-ever opto-thermo-electrohydrodynamic tweezers, optical nanotweezers that can trap and manipulate objects as small as proteins and viruses. The technique, developed by Justus Ndukaife and two graduate students in his group, gives researchers a powerful new tool for the study and perhaps early detection of viruses, cancer...

Hand-held robot points to less invasive prostate surgery

Jul. 18, 2019—Vanderbilt collaborators focused on minimally invasive prostate surgery are developing an endoscopic robotic system with two-handed dexterity at a much smaller scale than existing options. A key part of the design – telescoping, curved, concentric tubes – received U.S. patent protection in March 2019, the same month the principal investigators secured a $2.1 million R01...

FDA approves device based on Vanderbilt invention to ID parathyroid during head and neck surgeries

Dec. 17, 2018—Ten years after Professor of Biomedical Engineering Anita Mahadevan-Jansen discovered that parathyroid tissues glow under near-infrared light, the FDA has approved a device based on the technology for surgical use. She and her team developed the technology at the Vanderbilt Biophotonics Center. The device called “PTeye” has been tested at Vanderbilt University Medical Center and...

VISE symposium explores interoperative fluorescence to light up tumors

Dec. 18, 2017—Using fluorescently labeled antibodies as a contrast agent can give cancer surgeons highly specific real-time detection of tumors that may accelerate diagnosis, preserve more healthy tissue, and improve patient outcomes. “There is a tension between a positive margin and taking too much normal tissue,” said Dr. Eben Rosenthal, the John and Ann Doerr Medical Director...
