Abstract

A simple, rapid and ultrasensitive colorimetric detection of protein using aptamer–Au nanoparticles (AuNPs) conjugates based on a dot-blot array has been developed, which was combined with the unique optical properties of AuNPs, enabling the visual detection of protein within minutes without any instrument.
