❓ Frequently Asked Questions
What is advanced microscopy and imaging?
A set of high-end techniques that visualize structures at micro- and nanoscale, enabling detailed observation of cells, tissues, and materials beyond standard light microscopy.
How does confocal microscopy work?
It uses focused laser light and a pinhole to reject out-of-focus light, producing sharp optical sections and 3D reconstructions of fluorescent samples.
What distinguishes electron microscopy from light-based methods?
Electron microscopy uses electron beams with much shorter wavelengths, achieving much higher resolution but requiring vacuum conditions and usually heavy-metal staining (e.g., TEM, SEM).
What is super-resolution microscopy?
A group of techniques that surpass the diffraction limit of light to resolve features below ~200 nm, using methods like STED, PALM/STORM, or structured illumination (SIM).
What are common applications of advanced microscopy?
Visualizing subcellular structures, protein localization, tissue organization, cellular dynamics, and nanoscale properties in materials science.
