Light Acquisition02:16

Light Acquisition

9.6K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Light as Energy01:35

Light as Energy

95.9K
The energy required to carry out photosynthesis is light— typically electromagnetic radiation from the sun. The range of all possible wavelengths is known as the electromagnetic spectrum.
Photons
A photon is a discrete electromagnetic particle or bundle of energy. Photons are characterized by their frequency, wavelength, and amplitude, similar to the properties of a wave. Waves with higher frequencies transmit more energy and have shorter wavelengths than longer wavelengths that transmit...

The Wave Nature of Light02:12

The Wave Nature of Light

61.2K
The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and prisms and was able to demonstrate that white light consists of the individual colors of the rainbow combined together. Newton explained his optics findings in terms of a "corpuscular" view of light, in which light was composed of streams of extremely tiny particles traveling at high speeds according to Newton's laws of motion.

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

5.8K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Area of Science:

  • Cell Biology
  • Microscopy
  • Bioengineering

Background:

  • Light-sheet fluorescence microscopy (LSFM) is a powerful imaging technique with low phototoxicity and high resolution, suitable for various scales from single cells to small organisms.
  • Microdevices (bioMEMS) offer controlled environments for cell studies, mimicking in vivo conditions and enabling precise manipulation.
  • Current microdevices are often designed for confocal microscopy, which has limitations like higher phototoxicity and slower imaging speeds compared to LSFM.

Purpose of the Study:

  • To explore approaches for achieving single-cell and subcellular resolution using LSFM within microdevices.
  • To highlight the advantages of LSFM for 3D characterization of active cells in microfluidic systems.
  • To provide guidance on improving LSFM experiments with microdevices for advanced biological studies.
