The ability to control protein and cell positioning on a microscopic scale is crucial in many biomedical and bioengineering applications, such as tissue engineering and the development of biosensors. We propose here a novel, simple, and versatile method for the micropatterning of proteins. Micropatterned substrates are produced by the dewetting of a metastable polymer film on top of another polymer film. Selective adsorption, or micropatterning, of proteins can be achieved on such substrates by...[Show more]
