Danish researchers have made a nano-sized box out of DNA that can be locked or opened in response to 'keys' made from short strands of DNA. By changing the nature or number of these keys, it should be possible to use the boxes as sensors, drug delivery systems or even molecular computers.
Diagnosis and treatment in one go: Korean researchers led by Tae Gwan Park and Jinwoo Cheon have developed the basis for a four-in-one agent that can detect, target, and disable tumor cells while also making them macroscopically and microscopically visible.
A clever materials science technique that uses a silicon crystal as a sort of nanoscale vise to squeeze another crystal into a more useful shape may launch a new class of electronic devices that remember their last state even after power is turned off.
The Camille and Henry Dreyfus Foundation announced today that George M. Whitesides, the Woodford L. and Ann A. Flowers University Professor of Chemistry at Harvard University, has won the inaugural Dreyfus Prize in the Chemical Sciences.
