Sorry, no etymologies found.
This tiny worm became temporarily paralyzed when scientists fed it a light-sensitive material, or "photoswitch," and then exposed it to ultraviolet light.
By using intravital imaging, the researchers developed a "photoswitch" to mark cancer cells of their choosing within a tumour and study how these tumour cells in mice move in their surrounding tissue.
One such protein, the glutamate receptor, has been put under the control of a photoswitch and introduced into the retinas of mice.
The photoswitch turns the glutamate receptor on or off by changing its shape depending on the wavelength of light used — a technique that's been shown to induce light sensitivity in blind mice.
The JACS report describes development and successful testing of a photoswitch composed of the light-sensitive material, dithienylethene.
The material known as dithienylethene was used in the new investigation, to set the basis for the photoswitch.
However, the structure / functional basis of the phytochrome photoswitch is still unclear.
