Isolated composite drug and carrier nanoparticles

A process for the preparation of a composite comprising a carrier particle and a plurality of drug nanoparticles. The process comprises providing a suspension of drug nanoparticles in the presence of a carrier particle, the carrier particle having an external surface that is functionalised with a surface treatment agent. The process simplifies isolation of drug nanoparticles from suspension.

De novo design of protein switches

Disclosed are protein switches that can sequester bioactive peptides and/or binding domains, holding them in an inactive (off) state, until combined with a second designed polypeptide called the key, which induces a conformational change that activates (on) the bioactive peptide or binding domain, components of such protein switches, and their use.
