Light-responsive nanozymes for biosensing
The Analyst, 2020Using light as an external stimulus plays a key role not only in modulating activities of nanozymes, but also in constructing efficient biosensing systems.

Recent advances in the development of light-inducible transgene expression systems have overcome many inherent drawbacks of conventional chemically regulated systems. The latest generation of those light-regulated systems that are specifically responsive to different wavelengths allows spatiotemporal control of gene expression in a so far unprecedented

Photosynthetic light-response curves
Planta, 1993Gradients in photosynthetic capacity through the leaf affect the shape of the irradiance-response curve. These gradients in photosynthetic capacity were manipulated by restraining leaves in different orientations. The shape or curvature of the light-response curve can be defined by Θ, where Θ=0 is a rectangular hyperbola and Θ=1 is a Blackman curve ...

![Figure][1] Many migrating animals, including insects, rely on a celestial compass to navigate. They mostly use UV and polarised light, which are invisible to humans. While waves of unpolarised light are orientated in many different planes, some sunlight is scattered by the atmosphere ...

Combining heat and light responses
Science, 2016Plant Science Plants integrate a variety of environmental signals to regulate growth patterns. Legris et al. and Jung et al. analyzed how the quality of light is interpreted through ambient temperature to regulate transcription and growth (see the Perspective by Halliday and Davis).

Light-Response Curves in Land Plants
2018Light is the driving force for photosynthesis. Two techniques are commonly employed to help characterize the relationship between the light environment and photosynthesis in plants.Chlorophyll a fluorescence analysis is used to examine both the capacity for and the efficiency of the conversion of absorbed light into energy for photosynthesis ...

Light-responsive musical instrument
The Journal of the Acoustical Society of America, 1986A musical instrument that produces whistle-type tones responsive to the impingement of sunlight or other source of electromagnetic radiation upon one or more radiation-absorbent porous-to-air, generally disc-shaped generator member or members disposed interiorly and in the lower half of a vertically oriented transparent or partially transparent tube ...

Light-Responsive Polyelectrolyte/Gold Nanoparticle Microcapsules
The Journal of Physical Chemistry B, 2005We report the preparation and characterization of light-responsive delivery vehicles, microcapsules composed of multiple polyelectrolyte layers and light-absorbing gold nanoparticles. The nanostructured capsules were loaded with macromolecules (fluorescein isothiocyanate-labeled dextran) by exploiting the pH-dependence of the shell permeability, and ...

Light-responsive Wormlike Micelles
2015UV/Vis light as a trigger displays a set of advantages over other types of stimuli in terms of its “clean” character, low cost, and precise spatial localization, and for these reasons it has been widely exploited in the development of smart materials.
