Scientists succeed in designing artificial enzymes that also undergo 'evolution in a test tube' (3/27/2008)

>Mankind triumphed in a recent 'competition' against nature when scientists succeeded in creating a new type of enzyme for a reaction for which no naturally occurring enzyme has evolved. This achievement opens the door to the development of a variety of potential applications in medicine and industry. ...> Full Article

Biocapture surfaces produced for study of brain chemistry (12/17/2007)

Researchers have developed a novel method for attaching small molecules, such as neurotransmitters, to surfaces, which then are used to capture large biomolecules. By varying the identity and spacing of the tethered molecules, researchers can make the technique applicable to a wide range of bait molecules including drugs, chemical warfare agents and environmental pollutants. Ultimately, the researchers also hope to identify synthetic biomolecules that recognize neurotransmitters so that they can fabricate extremely small biosensors to study neurotransmission in the living brain. ...> Full Article
