DNA Circuits to Identify Cancer Cells
Researchers from Duke University have developed a new DNA-based tool to identify cancer cells. Their system is a DNA circuit. DNA binding to specific cell markers produces a signal if and only if two specific proteins are present, helping to...

Self-Propelled Enzyme-Coated Liposomes for Drug Delivery
Researchers at Penn State have developed self-propelled liposomes that can migrate towards or away from chemical signals, paving the way for self-directed drug delivery vehicles that can actively target a specific area in the body. The technology...

Optical Nanoprobes Monitor Neural, Cardiac Cell Activity
Monitoring neurons and other excitable cells in vivo for research and clinical applications has usually required the use of electrode arrays. These are quite limited in their electrode density and the area that they can cover. Moreover, the amount...

Microscopic Donuts Swim On Their Own to Deliver Therapies Inside Body
While there has been a great deal of work on a variety of micro- and nanoparticles that can deliver drugs and other therapies within the body, compared with bacteria they're extremely rudimentary in how they can move within the body. Most are...
