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...

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...

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.

We present protocols for the 3-dimensional (3D) encapsulation of cells within synthetic hydrogels. The encapsulation procedure is outlined for two commonly used methods of crosslinking (michael-type addition and light-initiated free radical mechanisms), as well as a number of techniques for assessing encapsulated cell behavior.
FAQs
The cross-linked network preserves the sample’s three-dimensional organization while its pores support movement of nutrients, signaling molecules, and waste products. This combination lets researchers study biological behavior in a spatially organized setting rather than treating cells or biomolecules as isolated components. The matrix therefore supplies both physical support and a route for molecular exchange.
Matrix stiffness acts as a controllable physical cue, while polymer composition and cross-linking conditions help define the surrounding environment. Researchers can vary these parameters to create matrices that model different tissue-specific settings and then examine how physical and biochemical signals influence cell behavior, development, or disease-related processes. The value lies in tuning the environment instead of using one fixed matrix.
Retaining structural organization is especially important when the research question depends on interactions within a three-dimensional arrangement. Hydrogel embedding provides a setting for examining tissues, organoids, or cells while maintaining spatial relationships within the matrix. This makes it relevant to studies of development and disease, where behavior may depend on both biological components and the surrounding physical environment.
Researchers first choose a hydrogel-forming polymer and place the cells, tissue, or biomolecules within the intended matrix environment. They then cross-link the polymer around the sample, creating the porous three-dimensional structure. Composition, cross-linking conditions, and stiffness are adjusted according to the biological model, so the resulting construct matches the tissue-specific setting being investigated.
The matrix can maintain the structural organization of biological specimens in a three-dimensional format, making hydrogel embedding useful for imaging. Researchers can examine cells, tissues, or other biological material within an organized environment rather than relying only on isolated components. This supports visualization alongside studies of tissue structure, organoids, and cellular behavior.
Applications include three-dimensional cell culture, tissue engineering, organoid studies, and imaging of biological specimens. The same general strategy can be adapted by changing polymer composition, cross-linking conditions, or matrix stiffness. That flexibility allows investigators to use hydrogel embedding across models while asking how environmental cues affect cell behavior, development, and disease.
