Abstract

Thermodynamically reversible addressing of proteins (TRAP) is demonstrated. A stimuli-responsive elastin-like polypeptide fused to thioredoxin is used to reversibly address the fusion protein onto a chemically micropatterned surface template by switching the interaction between the surface and the stimuli- responsive polypeptide (see Figure).
