Förster resonance energy transfer (FRET) imaging is a powerful tool for real-time cell biology studies. Here a method for FRET imaging cells in physiologic three-dimensional (3D) hydrogel microenvironments using conventional epifluorescence microscopy is presented. An analysis for ratiometric FRET probes that yields linear ratios over the activation range is described.

Collagen is another widely used biomaterial that has found popularity in commercial applications, such as photography. Collagen has more recently been used in tissue engineering applications, by creating hydrogels that provide structure to engineered tissue. This video introduces collagen as a biomaterial, demonstrates how it is harvested from porcine skin, and shows how the material is used to create a hydrogel for tissue engineering applications. Finally, several applications of the material...

Source: Amber N. Barron, Ashlea Patterson, and Taylor D. Sparks, Department of Materials Science and Engineering, The University of Utah, Salt Lake City, UT Hydrogels are a versatile class of cross-linked polymers produced through relatively simple procedures and with generally inexpensive materials. They can be formed from solution and involve a polymer backbone formed from monomer reagents, an initiator which makes the polymer reactive and a crosslinking species which binds the polymer chains...

FAQs
Fluorescent labels can make selected cells, molecules, or matrix components visible, while intrinsic optical contrast can reveal features without relying on an added label. These signals allow investigators to examine hydrogel architecture, composition, and biological interactions from complementary perspectives. Choosing the signal according to the feature of interest helps connect visible structure with cellular behavior or molecular distribution.
Swelling and degradation change the hydrogel network over time, so imaging can document how its structure evolves under biological conditions. Measuring these changes helps relate matrix behavior to transport and mechanical properties. In applications such as tissue-engineering scaffolds or drug delivery systems, those observations support material optimization by showing whether the hydrogel maintains or loses its intended structure.
Images of hydrogel architecture provide structural information that can be compared with the movement of molecules and the behavior of encapsulated or interacting cells. This relationship is important because network organization may help explain transport patterns, mechanical behavior, and cellular responses. Linking these observations gives researchers a way to evaluate how material design influences biological performance.
Researchers use fluorescent labels, intrinsic optical contrast, or other detectable signals to follow cells or molecules within the hydrogel. The resulting images can show where these components are located and how their interactions relate to the surrounding matrix. This capability is especially useful when evaluating cell encapsulation, molecular distribution, or interactions between a biomaterial and a biological system.
A supported workflow begins by selecting an imaging signal suited to the feature being examined, such as fluorescent labeling for selected components or optical contrast for matrix structure. Researchers then visualize and measure architecture, composition, swelling, degradation, or internal cells and molecules. The measurements are interpreted alongside transport, mechanical behavior, and cellular responses to assess material performance.
In tissue engineering, imaging helps evaluate hydrogel scaffolds, cell encapsulation, and biomimetic extracellular matrices. In drug delivery research, it can show structural changes and help examine how molecules are distributed within the material. Across these applications, the approach supports comparison of hydrogel designs by connecting their observed organization and interactions with biological performance.
