New methods of gene delivery using lasers

...ful, and in contrast to other methods the team can select individual cells to be treated at will under the microscope. The new technique involves the violet laser being focused onto cell membranes for a fraction of a second ?this causes the membrane to open up, allowing foreign genes to enter. The cell’s i...

Ophthalmologists Use Artificial Silicon Retina Microchip To Treat Vision Loss
