Technology could save wasted money

teaser

Engineers have developed a revolutionary technique that could reduce the cost of making drugs.

Aimed at conquering “polymorpshism” – a change that alters the particle structure of chemicals and costs pharmaceutical companies millions of pounds each year – the new technology looks set to make “right first time” crystal formation a reality.

The system, developed by scientists at the University of Leeds in conjunction with drug company PLIVA, uses monolayers, a collection of self-organising molecules, to ensure consistent crystal formation in traditional chemical reactors.

Professor Kevin Roberts said the technology works in a similar fashion to the way oil sits on top of water, adding simplicity is the key to its success.

“We’ve shown that we can produce a well-defined crystal structure using a self-assembled monolayer bound onto a metal substrate within a regular reactor,” he said.

“This is exciting stuff, because it’s a relatively simple system that could make a huge difference in the efficiency of drug manufacture.”

“It has huge potential commercially. Our next steps are to make sure it’s just as efficient on an industrial scale.”
