Ligand crosslinking is known to improve the colloidal stability of nanoparticles, particularly in aqueous solutions. However, most crosslinking is performed chemically, in which it is difficult to limit interparticle crosslinking, unless performed at low concentrations. Photochemical crosslinking is a promising approach, but usually requires ultraviolet (UV) light to initiate. Using ...

We developed a light-mediated system based on synthetic light-switchable transactivators. The transactivators binds promoter upon blue-light exposure and rapidly initiate transcription of target transgenes in filamentous fungus Trichoderma reesei. Light is inexpensive to apply, easily delivered, and instantly removed, and thus has significant advantages over chemical inducers.

Prolonged exposure to a stimulus results in a subsequent perceptual bias. This perceptual adaptation aftereffect occurs not only for simple stimulus features but also for high-level stimulus properties (e.g., faces' gender, identity and emotional expressions). Recent studies on aftereffects demonstrate that adaptation to human bodies can modulate face perception because ...

Many retinal imaging instruments use infrared wavelengths to reduce the risk of light damage. However, we have discovered that exposure to infrared illumination causes a long-lasting reduction in infrared autofluorescence (IRAF). We have characterized the dependence of this effect on radiant exposure and investigated its origin. A scanning laser ophthalmoscope ...
