Persp1 2000fibersWe develop a variety of nanomaterial-based systems including nanofibers. Electrospun nanofibers have been demonstrated by Antje Baeumner and her colleague, Margaret Frey from the Dept. of Fiber Science at Cornell University to be promising nanomaterials for bioanalytical sensors. Nanofibers can be created bearing diverse surface chemistries ranging from hydrophilic to hydrophobic or have amphoteric characteristics. They may bear functional groups, are biocompatible, non-fouling, and are capable to present biologically active molecules such as biotin on their surface. The nanofibers provide an immense surface-to-volume ratio and are therefore ideal components for integration into microfluidic devices or for paper-based microfluidics and lateral-flow assays. The Baeumner team investigates nanofibers for separation of analytes, immobilization of biorecognition elements, as detectors and also as mixing components. Dr. Nongnoot Wongkaew spearheads the development of conductive nanofibers in the institute.
