We demonstrate the use of PEDOT:PSS conducting polymer nanowires for the local control of protein concentration in water and biological media.  These small, flexible, conductive, and biologically compatible PEDOT:PSS nanowires provide a new tool for the electrical control of biological systems.
PEDOT:PSS
We use fluorescence microscopy to compare the localization of serum albumin in response to electric fields generated by narrow (760 nm) and wide (1.5 μm) nanowires.
