Cell imaging and microscopy techniques allow researchers to visualize and study the structure and function of cells and their components, providing insights into cellular processes, interactions, and dynamics.

Brightfield microscopy is a type of light microscopy that uses a series of lenses to focus light on a specimen, allowing for the visualization of cellular structures and components based on their light-absorbing properties.

Fluorescence microscopy relies on the selective excitation and emission of light by fluorescent molecules, allowing for the visualization and localization of specific cellular components or molecules of interest.

Confocal microscopy is a technique that uses a focused laser beam to generate three-dimensional images of biological specimens by selectively illuminating and detecting light from different depths within the sample.

Electron microscopy offers higher resolution and magnification compared to light microscopy, allowing for the visualization of ultrastructural details and subcellular components at the nanometer scale.

Atomic force microscopy (AFM) is a technique that uses a sharp probe to scan the surface of a specimen, providing information about its topography, mechanical properties, and local interactions.

Live-cell imaging techniques often involve the use of light or other forms of energy, which can potentially cause phototoxicity and damage to cellular components, limiting the duration and frequency of imaging experiments.

Time-lapse microscopy involves capturing a series of images over time, allowing for the visualization and analysis of dynamic cellular processes, such as cell division, migration, and interactions.

Fluorescent dyes and probes are used in cell imaging to selectively label and visualize specific cellular structures or molecules, enhancing their contrast and visibility for microscopic observation.

Structured illumination microscopy (SIM) is a super-resolution microscopy technique that uses structured illumination patterns to achieve nanoscale resolution, allowing for the visualization of cellular structures and components beyond the diffraction limit.

Cryo-electron microscopy (cryo-EM) offers the advantage of preserving biological samples in their native state by rapidly freezing them, allowing for the visualization of cellular structures and macromolecules in their natural conformation.

Patch-clamp electrophysiology is a technique used to study the electrical properties of cells by recording ionic currents through ion channels and transporters in the cell membrane.

Förster resonance energy transfer (FRET) microscopy relies on the transfer of energy between two fluorescent molecules, allowing for the visualization and measurement of molecular interactions and conformational changes.

Atomic force microscopy (AFM) is commonly used to study the mechanical properties of cells and tissues by measuring forces and interactions at the nanoscale, providing insights into cellular mechanics and tissue stiffness.

Scanning probe microscopy (SPM) techniques, such as atomic force microscopy (AFM), are limited in their ability to visualize internal cellular structures due to their surface-scanning nature, making them primarily suitable for studying the topography and mechanical properties of cell surfaces.
