Micropatterned surfaces with covalently grafted unsymmetrical polyoxometalate-hybrid clusters lead to selective cell adhesion

J Am Chem Soc. 2009 Feb 4;131(4):1340-1. doi: 10.1021/ja807091v.

Abstract

Mn-Anderson based polyoxometalate clusters with different terminal groups have been patterned successfully onto self-assembled monolayer (SAM) using microcontact printing. Studies of the interactions between the designed SAMs and human fibroblast (hTERT-BJ1) cells have been reported, and it was observed that cells attach and spread efficiently for monolayer presenting a terminal aromatic pyrene platform with a polyoxometalate Mn-Anderson cluster as linker, demonstrating the crucial role played by the polyoxometalate metal oxide cluster as an intermediary in cell adhesion to the surface.
