Area of Science:

  • Histotechnology
  • Biomedical Engineering
  • Diagnostic Pathology

Background:

  • Microwaves (MWs) were initially used for tissue fixation over 20 years ago.
  • Their application has expanded beyond simple fixation to encompass broader laboratory processes.

Purpose of the Study:

  • To highlight the extended applications and benefits of microwave technology in histopathology.
  • To demonstrate the efficiency and improved results of MW-accelerated techniques.

Main Methods:

  • Utilizing microwaves to accelerate tissue fixation and processing, including paraffin embedding.
  • Employing MW-stimulated special stains and immunohistochemical procedures.
  • Applying MWs for electron microscopy sample preparation and resin polymerization.
