Abstract

Protein patterning on solid surfaces is a topic of significant importance in the fields of biosensors, diagnostic assays, cell adhesion technologies, and biochip microarrays. In this letter, we have established a novel, rapid method for the fabrication of a “protein recording material”, which enables us to spatiotemporally regulate the recording, reading, and erasing of a fluorescent protein array as information by a photochemical technique. A photolinker that we synthesized here was used to control the protein array spatiotemporally. The recording process was almost completed after 1 min of photoirradiation to read a clear pattern consisting of a specific protein−ligand complex with high spatiotemporal resolution. The erasing of the protein array was then achieved by photoirradiation onto the entire patterned surface.
