Pushing and pulling droplets with graphene

Scientists have moved liquid droplets using long chemical gradients formed on graphene. The change in concentration of either fluorine or oxygen formed using a simple plasma-based process either pushes or pulls droplets of water or nerve agent simulant across the surface. This new achievement offers potential applications ranging from electronics to mechanical resonators to bio/chemical sensors.

$24 million project to develop 'body on a chip'

Whether it's the Ebola virus or Sarin and Ricin, a key to responding to chemical or biological attacks is having effective antidotes at the ready. To accelerate the development of new therapies, Wake Forest Baptist Medical Center's Institute for Regenerative Medicine is leading a unique $24 million federally funded project to develop a 'body on a chip' that will be used to develop these countermeasures.

Nanodiamonds to boost treatment of chemoresistant leukemia

By binding multiple molecules of a common leukemia drug with nanodiamonds, scientists from the National University of Singapore (NUS) and University of California, Los Angeles (UCLA) managed to boost the delivery of the drug to leukemic cells and retain the drug within the cells to combat the cancer.

New magnetic semiconductor material holds promise for spintronics

Researchers at North Carolina State University have created a new compound that can be integrated into silicon chips and is a dilute magnetic semiconductor -- meaning that it could be used to make "spintronic" devices, which rely on magnetic force to operate, rather than electrical currents.
