Microscopyarerelated, a label for topics related to microscopy, is not a standard term in practice. This article uses microscopy-related concepts to describe imaging methods that reveal structure and processes at scales from cells to molecules. It encompasses optical techniques based on visible light, non-optical methods using electrons or scanning probes, and specialized modalities for contrast, labeling, or spectroscopy.

Optical microscopy includes bright-field, phase-contrast, differential interference contrast, and polarized light methods. Fluorescence microscopy uses fluorescent labels to visualize specific components, while confocal and spinning-disk systems provide optical sectioning for three-dimensional reconstructions. Super-resolution optical techniques such as STED, PALM, and STORM push beyond the conventional diffraction limit.

Electron microscopy relies on electron beams to achieve higher resolution. Transmission electron microscopy reveals internal structure in thin samples, whereas scanning electron microscopy images surfaces with detailed topography. Cryo-electron microscopy preserves specimens in a near-native state, enabling high-resolution structures of biomolecules and complexes.

Scanning probe microscopy, including atomic force microscopy and scanning tunneling microscopy, maps surface properties at the nanoscale, often in air or liquid. Raman microscopy combines spectroscopy with imaging. Correlative light and electron microscopy links fluorescence and electron images for multimodal analysis.

Microscopy requires careful sample preparation and instrumentation; each modality has limitations in resolution, contrast, potential artifacts, and data volume. Ongoing advances in detectors, labeling, computing, and automation expand capabilities for live-cell imaging, materials science, and industrial metrology.
