ce reproducibility and image clarity. Specimen Preparation Techniques Proper specimen preparation is crucial to achieving meaningful results. Depending on the application, samples may require staining, mounting, or sectioning. The Royal Microscopical Society stresses the importance of ch
transmission electron microscopy (TEM)? In TEM, a high-energy electron beam is transmitted through an ultra-thin specimen. The electrons interact with the specimen's internal structure, resulting in variations in amplitude and phase of the electron wave. These
Sample Fixation and Embedding Preserve the native structure of biological samples using fixatives like glutaraldehyde or osmium tetroxide. Embed samples in resin (e.g., epoxy) for stability during sectioning or thinning. 2. Sectioning or Thinning Use ultramicrotomy for b

for developing new materials and improving manufacturing processes. #### Biology and Medicine AFM, in particular, has become a vital tool for studying biological samples such as cells, proteins, and DNA. It allows researchers to observe structural details and mechanical propertie
y and uniformity of thin films and nanostructured materials. Using AFM and KPFM, researchers can image the surface morphology and map the local electric potentials of perovskite and organic photovoltaic layers. This reveals imperfections such as grain boundaries, defects, and charge traps that reduce

Applications of SPM in Energy Materials and Devices The integration of SPM techniques into energy research has led to significant breakthroughs across various domains: 1. Catalysis and Electrocatalysis Su
e. As the tip moves, various forces—such as van der Waals forces, electrostatic forces, and chemical bonding—cause the cantilever to deflect. A laser beam reflects off the back of the cantilever onto a photodetector, which measures tiny changes in the cantilever’s position with extreme sensitivity. T
