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...

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.

FAQs
Polymer swelling controls how much water the network retains, while network architecture determines available space and pathways within the material. Together, these features influence porosity and transport, including movement of encapsulated proteins or therapeutic molecules. Researchers can therefore adjust swelling and architecture to create platforms that support biological contents while providing more predictable material behavior.
Crosslinking chemistry, polymer composition, and degradation conditions jointly control stiffness, porosity, transport, and stability. Altering the crosslinking chemistry changes the network structure, while polymer composition affects the material environment. Degradation conditions can further modify the network over time. Considering these variables together helps researchers design a platform suited to a particular biological or engineering application.
Mechanical and biochemical tuning allows a platform to reproduce selected aspects of the extracellular matrix, the material environment surrounding cells. This matters because material properties can influence cell behavior and tissue formation. By adjusting these features, researchers use hydrogels not only as culture environments but also as experimental variables for investigating how material design affects biological development.
Degradation conditions determine how long the polymer network remains stable and whether its structure changes during use. Because degradation can modify stiffness, porosity, transport, and overall stability, it becomes a design variable rather than a secondary consideration. In bioengineering, selecting suitable degradation behavior helps maintain an appropriate environment for cells, proteins, or therapeutic molecules.
Hydrogel platforms can encapsulate cells, proteins, or therapeutic molecules within their hydrated networks. Encapsulation places these biological components in a configurable material environment whose stiffness, porosity, transport, and stability can be adjusted through network design. This capability supports tissue models, drug delivery approaches, and regenerative strategies while linking material properties to the behavior or availability of the incorporated components.
Hydrogel-based tissue models provide a controlled setting for examining how material design influences cell behavior and tissue formation. Researchers can vary mechanical and biochemical properties to mimic selected extracellular matrix features, then study the resulting biological responses. This makes the platform useful for connecting polymer network design with tissue-related outcomes in bioengineering research.
These designs are used when a hydrated, configurable material environment can support biological contents or therapeutic molecules. Their adjustable stiffness, porosity, transport, and stability make them relevant to drug delivery, wound care, and regenerative strategies. The appropriate design depends on how polymer composition, crosslinking chemistry, and degradation conditions align with the intended application and biological context.
