Abstract
Conjugation with artificial nucleic acids allows proteins to be modified with a synthetically accessible, robust tag. This attachment is addressable in a highly specific manner by means of molecular recognition events, such as Watson-Crick hybridization. Such DNA-protein conjugates, with their combined properties, have a broad range of applications, such as in high-performance biomedical diagnostic assays, fundamental research on molecular recognition, and the synthesis of DNA nanostructures. This Review surveys current approaches to generate DNA-protein conjugates as well as recent advances in their applications. For example, DNA-protein conjugates have been assembled into model systems for the investigation of catalytic cascade reactions and light-harvesting devices. Such hybrid conjugates are also used for the biofunctionalization of planar surfaces for micro- and nanoarrays, and for decorating inorganic nanoparticles to enable applications in sensing, materials science, and catalysis.
