A method is described whereby quantum dot (QD) nanoparticles can be used for correlative immunocytochemical studies of epoxy embedded human pathology tissue. We employ commercial antibody fragment conjugated QDs that are visualized by widefield fluorescence light microscopy and transmission electron microscopy.

The light microscope is an instrument used by researchers in many different fields to magnify specimens to as much as a thousand times their original size. In its simplest form, it is composed of a clear lens that magnifies the sample and a light source to illuminate it. However, most light microscopes are much more complex and house numerous fine-tuned lenses with tightly controlled dimensions all within the body of the microscope itself and in components such as the objectives and eyepieces.

Scanning Electron Microscopy (SEM)

Source: Laboratory of Dr. Andrew J. Steckl — University of Cincinnati A scanning electron microscope, or SEM, is a powerful microscope that uses electrons to form an image. It allows for imaging of conductive samples at magnifications that cannot be achieved using traditional microscopes. Modern light microscopes can achieve a magnification of ~1,000X, while typical SEM can reach magnifications of more than 30,000X. Because the SEM doesn’t use light to create images, the resulting pictures it...
FAQs
The objective lens determines how much of the specimen contributes to the image. A modest-magnification objective collects information from a larger area, allowing researchers to inspect coverage, organization, and relationships among structures in the same view. This broad sampling supports system-level assessment, although the resulting image does not resolve fine details as effectively as higher-magnification imaging.
The optical system and detector work together to convert light from the specimen into a visible image. Their performance affects how clearly the large-area information collected by the objective can be examined. In bioengineering studies, this image supports evaluation of overall architecture, spatial organization, and changes across engineered samples rather than only isolated microscopic features.
Low-magnification imaging is preferable when the research question concerns broad structure, sample coverage, or relationships across a specimen. High-magnification methods provide greater fine-detail resolution, but they examine a smaller region and may not show how local features fit into the larger system. The appropriate choice therefore depends on whether organization or cellular detail is the primary outcome.
A broad field of view links local observations to the architecture and performance of the engineered system. It can reveal whether cells cover a scaffold, how tissue occupies a construct, or how structures are arranged within a microfluidic device. This perspective helps researchers interpret cellular behavior in relation to design features and large-scale sample changes.
Researchers can use repeated low-magnification observations to follow large-scale changes in cell cultures, engineered tissues, biomaterials, or microfluidic devices. Images can show changes in tissue growth, scaffold architecture, and sample coverage as the experiment progresses. The method is especially useful for rapid inspection when the main objective is tracking overall development rather than resolving fine cellular detail.
Applications include examining cell-culture coverage, evaluating scaffold architecture, following tissue growth, and inspecting microfluidic devices. These uses all depend on seeing how structures occupy and relate to one another across a relatively large area. The resulting observations can support assessment of whether a biomaterial or engineered construct is developing in a pattern consistent with its intended design.
