Bovine capillary endothelial cells adhered on a micropatterned gold substrate backfilled with a cell repellent ethylene glycol-terminated SAMs. Application of a −1.2 V voltage pulse (30 s) caused SAMs desorption and subsequent protein adsorption on the bare gold. This enabled cells attachment and migration on previously inert areas. Top left insets indicate the minutes elapsed after the voltage pulse. Reprinted with permission from Jiang et al. (2003).
