Photodynamic therapy involves the injection of a light-sensitive medicine called verteporfin into a vein in the arm.
The light-sensitive area on each CCD detector measures 45.0mm by 59.0mm, encompassing 1, 966 pixels by 4, 500 pixels.
The technique begins with the placing of light-sensitive proteins from green algae inside specific types of brain cells.
The viruses used to deliver the light-sensitive proteins can be engineered to target very specific clusters of brain cells.
Design-wise, the most spectacular aspect of Terminal 2 is its lattice roof, which is studded with special, light-sensitive lenses that look like peacock feathers overhead.
That's the trick performed by holographic disk drives, which record a series of 1-million-bit chunks of data as holographic "pages" inside a light-sensitive plastic medium.
Threaded on a wire one-fifth the thickness of a human hair, these tiny seeds of light can be injected to activate special networks of light-sensitive neurons.

Depending on just how researchers tailor the virus that carries the light-sensitive protein, they now can target almost any type of neuron they want to study.
WSJ: Scientists Cast Light Onto Roots of Illness Deep in the Brain
Researchers at Stanford University and MIT's Picower Institute for Learning and Memory had activated light-sensitive neurons in the brain's hippocampus involved in the memory of fright.

The goal was to substitute photoreceptors with a light-sensitive material capable of restoring photosensitivity to the retina, by easing down the retina on a layer of organic photovoltaic semiconductor.
D. from Stanford and made his breakthrough almost immediately after starting his own lab in 2004, taking advantage of a 2002 discovery of light-sensitive proteins in green algae called channelrhodopsins.
This, Dr Silver is convinced, is because the activity in the light-sensitive neurons somehow activated a latent nerve pathway that spans both sides of the spinal cord, allowing them to synchronise.
The great advantage of a more light-sensitive camera is that you can make radical adjustments to the aperture, allowing filmmakers to indulge in what's become known as "bokeh porn" shallow depth-of-field shots in which sharply defined subjects are placed against artily smeared backgrounds.

The truth is, most bad headaches -- the ones that make getting through the day a chore or make you feel nauseated or sensitive to light -- are the Big M.
It was equipped with a 3.5m mirror - the largest monolithic mirror ever flown - and three state-of-the-art instruments sensitive to long wavelengths of light, in the far-infrared and sub-millimetre range (55 to 672 microns).
The near-infrared photoactive polymer absorbs more near-infrared light but is less sensitive to visible light, balancing solar cell performance and transparency in the visible wavelength region.

It is an interesting triple "coincidence, " which probably evolved over time, that our eyes are most sensitive to yellow-green light, which happens to be the characteristic color of sunlight as well as the color that can most easily be transmitted through the Earth's atmosphere.
The Center for Security Policy believes that the reckless German approach to control of sensitive dual-use technology now coming to light in Iraq is the rule, not the exception.
Dr Hoch's team extended this idea, arguing that as a plant starts to disassemble its light-gathering apparatus in preparation for winter, its leaves become particularly sensitive to light damage.
He realised that some of the off-the-shelf equipment used by serious amateurs is sensitive enough to measure the light drop caused by distant transits.
