White light takes hold in biology

World-first studies are underway at the University of St Andrews, exploring how a novel 'white light' laser could penetrate skin tissue more effectively than current laser surgery methods.

Let there be light

New light shed on drug-delivery techniques

Scientists at the University of St Andrews have developed non- invasive methods of moving and manipulating biological cells using lasers, which could have important implications for future methods of drug-delivery.

Lasers in medicine

Scientists in Scotland are developing new studies into how the latest laser trapping methods can assist in the safe and non-destructive delivery of therapeutic molecules into cells, which may lead to new, improved methods for drug delivery.

St Andrews science in national spotlight

Imagine a beam of light that can trap and manipulate microscopic objects like the tractor beam in Star Trek. Science fiction? No, science fact, thanks to the 'optical tweezers' used at the School of Physics and Astronomy at the University of St Andrews.

Lasers put tiny objects in a spin

University of St Andrews scientists have designed a novel way of spinning the most delicate microscopic objects - from a hamster chromosome to a glass bead - without damaging them.
