Preparation of Samples for Electron Microscopy

6.6K
To be visualized by an electron microscope, either transmission or scanning, biological samples need to be fixed (stabilized) so the electron beam does not destroy them and dried thoroughly (desiccated/dehydrated) so the vacuum does not affect them. Fixation needs to be done as quickly as possible because the sample properties will start changing as soon as it is removed from its natural environment. For example, in a tissue sample, the oxygen levels begin decreasing, causing an altered...

Area of Science:

  • Materials Science
  • Optics
  • Nanotechnology

Background:

  • Lead halide perovskites (LHPs) are promising semiconductor materials for laser applications due to their high optical gain and tunable wavelengths.
  • Solution-processible materials like LHPs offer advantages for fabricating microscale devices.
  • Environmental stability and enhanced performance are key challenges for LHP-based lasers.

Purpose of the Study:
