The phrase "activation light source" is correct and usable in written English.
It can be used in contexts related to technology, electronics, or devices that require a light source to indicate activation or functionality.
Example: "The device features an activation light source that illuminates when it is powered on."
Alternatives: "indicator light" or "power light source".
Thus, to avoid the use of UV as an activation light source, plasmonic effects of metal nanoparticles (mNPs), such as Au, Ag, and Pt, have been successfully hybridized, resulting in broad and strong light absorption in the visible region [13 16], as summarized in several recent review articles [17 21].
The activation light source illuminates the entire sample but at such a low intensity that only one or a few fluorophores are activated at a time, and the fluorophores that are activated at a given time is random.
The presence of the activator dye in conjunction with the photo-switchable emitter enabled tuning of the overall activation rate with a low-intensity visible activation light source, reducing potential photodamage.
For all experiments using multiple activation wavelengths for multicolor imaging, the appropriate activation light sources were pulsed in sequence to selectively activate different populations of fluorescent probes.
To image single-molecules with PALM microscopy, a 405 nm diode laser (Cube laser system, Coherent Inc., Santa Clara, CA) was the light source for photo-activation.
Activation of channelrhodopsin using a fibre-optic light source implanted in the hippocampus region of the animals' brains induced synchronous neuron firing and gamma oscillations.
Another interesting technique of PS activation that does not use an external light source is sonodynamic excitation by ultrasound.
The therapy involves the activation of light-sensitive drugs with a laser or other light source to generate reactive oxygen species (ROS).
Our setup (Fig. 1) consists of a light source for excitation, which may be complemented by another one for activation, and a CCD camera imaging the sample at a certain frame rate f.
Furthermore, some applications may require activation of a spatially dispersed set of neurons over a large area, in which case a single light source may not be adequate.
Alternatively, for measurements in which the 532 nm light source was employed to illuminate fiducial markers (see below), a 568 nm light source was used for activation of probes with Cy3 as the activator.
