The compartmentalization of proteins either within the plasma membrane or into intracellular locations is one regulatory mechanism that can greatly influence signaling outcomes; hence, to understand signaling it is important to study the spatial and temporal behavior of the proteins involved. We describe here a TIRF microscopy based system to study signal transduction in T cells, but is broadly applicable.

The early pioneers of microscopy opened a window into the invisible world of microorganisms. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes that leveraged nonvisible light, such as fluorescence microscopy that uses an ultraviolet light source and electron microscopy that uses short-wavelength electron beams. These advances significantly improved magnification, image resolution, and contrast. By comparison, the...

The best optical microscopes will typically have a resolution down to 200 nm in ideal...
FAQs
Image formation depends on how the specimen modifies the applied signal. A system may record transmitted, reflected, scattered, or emitted signal, while the instrument determines how that response becomes an image. This distinction affects which structural features can be observed and measured, including organization, morphology, and interactions within engineered biological systems.
Sample preparation influences how the specimen presents its structure to the instrument and therefore affects the resulting resolution and measurable features. Appropriate preparation helps preserve or expose relevant organization in cells, tissues, or biomaterials. In bioengineering studies, this is important when comparing morphology, material surfaces, or cell-material interactions across samples.
These approaches provide different ways to characterize a specimen. Bright-field, fluorescence, and confocal microscopy use light-based imaging, whereas electron microscopy uses electrons. The choice depends on the specimen, the signal of interest, the required scale of observation, and whether the study focuses on cellular morphology, tissue organization, or biomaterial surface characteristics.
The instrument and the way the specimen is prepared are central factors because both shape image resolution. The recorded signal also determines which specimen features become visible or measurable. Together, these choices influence whether an investigation can assess cellular organization, tissue structure, biomaterial surfaces, or behavior at cell-material interfaces.
A typical workflow begins by identifying the specimen and the structural or behavioral information required. Researchers then select a suitable imaging approach, prepare the sample, direct light, electrons, or another relevant signal onto it, and record the response. The resulting image can be evaluated for organization, morphology, surfaces, or interactions relevant to the study.
They are useful when researchers need to examine engineered tissue organization, biomaterial surfaces, cellular morphology, or interactions between cells and materials. Imaging provides measurable observations that can guide scaffold design and support evaluation of how biological components are arranged relative to engineered structures during development or testing.
Microscopy observations contribute to several bioengineering goals by making structural and behavioral features measurable. They can support scaffold design, disease modeling, and quality control, while also contributing to regenerative and diagnostic technology development. The selected imaging approach determines which aspects of cells, tissues, or biomaterials can be examined during these applications.
