Supramolecular linear coordination polymers of human serum albumin and haemoglobin

Abstract

We describe the synthesis, structure, and functionalities of water-soluble linear coordination polymers of human serum albumin and haemoglobin, which are connected via a bis(terpyridyl)–Fe²⁺ complex. These protein fibres were self-assembled by lyophilisation and were transformed into single-wall nanotubes. The biological activities of the protein units were perfectly preserved in the long fibres.
