Biocapture surfaces produced for study of brain chemistry

Courtesy of Penn State University - A research team at Penn State University has 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. The work is a part of and supported by the Center for Nanoscale Science at Penn State, a National Science Foundation Materials Research Science and Engineering Center.
