Phase Contrast and Differential Interference Contrast Microscopy

Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
X-ray Diffraction of Biological Samples01:10

X-ray Diffraction of Biological Samples

X-ray diffraction or XRD is an analytical tool that utilizes X-rays to study ordered structures such as crystalline organic and inorganic samples, polycrystalline materials, proteins, carbohydrates, and drugs.
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are  scattered by the electron clouds around the sample atoms. The  X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...

Area of Science:

  • Plant Biology
  • Biophysics
  • Imaging Science

Background:

  • Non-destructive imaging techniques are crucial for understanding plant anatomy and developmental processes.
  • Traditional methods often require sample sectioning or staining, limiting continuous observation.
  • Synchrotron-based X-ray imaging offers potential for advanced, non-invasive studies.

Purpose of the Study:

  • To demonstrate the utility of diffraction enhanced imaging (DEI) for non-destructive, continuous observation of plant seeds.
  • To evaluate DEI's capability in visualizing detailed anatomical structures and physiological events during seed development and germination.
  • To highlight DEI as a complementary imaging technique for plant science research.

Main Methods:

  • Utilized synchrotron-based X-ray imaging, specifically diffraction enhanced imaging (DEI).
  • Applied DEI to image various seed types, including Brassica napus L. and Triticum aestivum L. (caryopses).
  • Performed time-course imaging of individual germinating seeds to observe developmental processes.

Main Results:

  • DEI produced high-contrast, high-definition images of seed anatomical structures (e.g., hypocotyl-root axes, cotyledons, embryo axes, scutella).
  • Observed physiological events and developmental changes in germinating seeds over time without apparent radiation damage.
  • Successfully imaged embryo-less seeds and detailed structures like pericarp furrows and coleoptiles.

Conclusions:

  • DEI is a powerful, non-destructive technique for detailed plant seed anatomy and developmental studies.
  • DEI's contrast mechanism (refraction, scatter, attenuation) and use of high-energy X-rays minimize sample damage.
  • DEI provides unique, complementary insights into plant development, valuable for various research applications.
