Though not yet as functional as biological proteins, these artificial proteins created by physicists at the University of Vienna are the first versatile and modular examples of a fully artificial protein. Their method involves the self-assembly of simple particles into polymer chains. By controlling the interaction between the beginning and end of the polymer chain they are able to “lock” the folded end result.
Proteins are the molecular machines that form the building blocks of all living organisms, and underlie complex bio-molecular processes within our bodies. From muscle contraction to DNA replication, proteins are involved in uncountable biological activities. This research presents a foundation on which novel applications can be built, from material sciences to new forms of drug delivery. One day, these bionic proteins might very well be integrated into our own biology.
