In addition to providing a simple design strategy to create the next generation of self-regulated nanosystems, the scientists' discoveries also shed light on how natural biomolecular assemblies may have acquired their optimal dynamics.

How life appeared: rise of the nanomachines

The illustration depicts two chemical languages at the basis of molecular communication. The same white molecule, represented as a lock, is activated either via allostery (top) or multivalency (bottom). The allosteric activator (cyan) induces a conformational change of the lock while the multivalent activator provides the missing part of the lock, both enabling the activation by the key (pink).

The DNA-based nanotransporter developed by Alexis Vallée-Bélisle and his team can transport and deliver precise concentrations of drugs: in this picture, doxorubicin, a chemotherapeutic drug. These nanotransporters can also be attached to specific biomolecules to optimize drug distribution. Here, we see a nanotransporter (white) attached to albumin (pink) to maintain doxorubin (light blue) in blood circulation.

A rapid and portable drug detection device using bio-nanotechnology

Like a two-way radio that can both receive and transmit radio waves, the fluorescent nanoantenna designed by Alexis Vallée-Bélisle and his team receives light in one colour and depending on the protein movement it senses, then transmits light back in another colour, which we can detect. One of the main innovations of these nanoantennas is that the receiver part of the antenna (bright green) is also employed to sense the molecular surface of the protein studied via molecular interaction.
