Scientists at the University of St. Andrews have developed what they call a “light syringe,” which is able to deliver genes, drugs and other insoluble compounds into precise points of a target cell. Previously laser focusing issues made such a device impossible, however, the new design does not require focusing.

In the words of Dr. Frank Gunn-Moore:

The new form of laser has the ability to target any part of a cell without the need for exact focusing and is not stopped by objects placed in its way.

The light travels along an optic fiber that is the width of a human hair, which makes the light syringe a perfect complement to the endoscope.

According to Dr. Gunn-Moore:

We are very excited by these revolutionary new techniques. This method will allow us to build a machine that could be used with endoscopes. It will also allow us the potential to treat specific diseases and help in the testing of new drugs.

My guess is that this technology will become much more of a big deal for the application of genetic therapies in the not too distant future.
