Reversible Nanoparticle Electronics
Abstract
Phage and yeast both exhibit excellent resiliency to electric field exposure at low currents. The viability of phage and yeast in high voltage fields was tested, opening the door to the exploration of these species as medium for self-repairing electronics applications. Furthermore, survival after high field exposure suggested that electro-spun phage are likely to remain viable, even after they are incorporated into fabrics. Pulsed electric fields were used to successfully and reversibly release a tightly binding peptide from an electrode surface, and subsequently to transfer the peptide to the opposing electrode where the peptide reattached. A bipolar electrode configuration was demonstrated enabling the electric field driven release of biomaterials from a nonconductive surface. Additionally the experiments with yeast on sapphire indicate that under the right conditions the counteracting peptide and yeast surface charges can be overcome, enabling the electrically stimulated release of yeast from a material surface.
