Cutting nanoparticles down to size - new study

A new technique in chemistry could pave the way for producing uniform nanoparticles for use in drug delivery systems. Scientists have been investigating how to make better use of nanoparticles in medicine for several decades. Significantly smaller than an average cell, nanoparticles are more similar in size to proteins. This makes them good at interacting with biomolecules and transporting drug molecules attached to their surface across cell membranes. To date, however, only a handful of nanoparticle-based drugs have succeeded in reaching the clinic. This is because of the challenges in controlling the size and shape of nanoparticles - and understanding fully how these variables affect the way the particles behave in the body. In a new study researchers from the University of Birmingham and the University of Bath have demonstrated a technique that will allow chemists to more closely control the size and shape of nanoparticles.
