Read moreTargeted nanoparticles destroy prostate tumors
Biodegradable polymer nanoparticles, linked to a protein-binding nucleic acid known as an aptamer and loaded with the anticancer agent docetaxel, can target and kill prostate tumors growing in mice. Using this targeted nanoparticle to deliver docetaxel appears to reduce the toxic side effects associated with this drug.

Arrays of proteins attached to solid surfaces have become important tools in drug discovery and cancer diagnostics, but in general, the immobilized proteins themselves are inactivated by the processes used to create these arrays. Now, however, researchers at Northwestern University have used dip-pen nanolithography to create arrays of antibodies that retain their ability to bind to their biological substrates.

The porous, sieve-like minerals known as zeolites have been used for decades in purifiers, filters and other devices. Yet creating and refining a new type of zeolite is still a matter of sophisticated trial and error: no one has been able to figure out exactly how the crystals form, even in the laboratory.
