Delivering medicine directly to the affected area provides direct access to the diseased area. Nanoparticles hold promise as a delivery method but are currently only available in injectable forms. Now, researchers from MIT and Brigham and Women’s Hospital have made a breakthrough by finding a way of delivering nanoparticles orally. Nanoparticles loaded with chemotherapy drugs or short […]

Bacteria have a natural ability to attach themselves to surfaces, both natural and synthetic. Once attached, they often work cooperatively to form biofilms, thin layers of bacterial colonies that can coat the surface of a medical device and introduce the risk of infection. As a result, orthopedic implants, catheters, and even contact lenses can become […]

Scientists at the University of Leeds have perfected a new technique that allows them to make molecular nanowires out of thin strips of ring-shaped molecules known as discotic liquid crystals (DLCs). The findings could be an important step in the development of next generation electronic devices, such as light-harvesting cells and low-cost biosensors that could […]

By combining a new generation of piezoelectric nanogenerators with two types of nanowire sensors, researchers have created what are believed to be the first self-powered nanometer-scale sensing devices that draw power from the conversion of mechanical energy. The new devices can measure the pH of liquids or detect the presence of ultraviolet light using electrical […]

Material scientists at the Nano/Bio Interface Center of the University of Pennsylvania have demonstrated the transduction of optical radiation to electrical current in a molecular circuit. The system, an array of nano-sized molecules of gold, respond to electromagnetic waves by creating surface plasmons that induce and project electrical current across molecules, similar to that of […]

“That is important, because we could attach a drug to the aptamer so that the drug could get into a cell,” said Yanrong Wu, who recently completed her doctoral research at UF. Wu was the first author of a paper describing the findings in January in the Proceedings of the National Academy of Sciences. In allowing […]
