Watch the video "Chemotherapy Drugs Getting Better at Targeting Cancer Cells" redOrbit Staff & Wire Reports - Your Universe Online Changing the shape of chemotherapy drug nanoparticles to make them rod-shaped rather than spherical can enhance their effectiveness in targeting and treating breast cancer cells by as much as 10,000-fold, according to new research from bioengineers at the University of California, Santa Barbara (UCSB). As part of the research, a team led by Samir...

Ultrasound May Lead To Needle-Free Vaccinations

Lee Rannals for redOrbit.com — Your Universe Online MIT researchers are working on a technique that will allow needle-free vaccinations by using ultrasound waves. The team wrote in the Journal of Controlled Release that applying two separate beams of ultrasound waves can uniformly boost permeability across a region of skin more rapidly than using a single beam of ultrasound waves. “This could be used for topical drugs such as steroids – cortisol, for example –...

By Dinh, Anh-Tuan Pangarkar, Chinmay; Mitragotri, Samir Unlike macroscopic problems in mass, energy and momentum transfer, which are described by continuum equations, the movements and interactions of the nanoscale entities within a cell constitute a transport phenomenon known as discrete nanoscale transport (DNT). Imagine yourself on an alien spaceship, watching the daily goings- on of a large city through a telescope. You would see (among other things) complex transportation systems...
