Using Azobenzene‐Embedded Self‐Assembled Monolayers To Photochemically Control Cell Adhesion Reversibly

Abstract A celling point : A mixed self‐assembled monolayer comprising two types of alkanethiols—one containing an azobenzene unit terminated with a peptide, the other containing a hexa(ethylene glycol) group that resists nonspecific cell adhesion—enables cell adhesion to be modulated photochemically. The reversible conversion of the azobenzene moiety between E and Z configurations allows the surface to either support or resist cell adhesion. magnified image
