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...

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...
FAQs
Crosslinking joins or organizes dissolved polymers or biomolecules into a continuous network. Chemical reactions, physical interactions, or light-activated processes can initiate this transition, allowing the material to retain water after solidification. Because the network forms from the precursor composition, crosslinking connects solution design with the final gel’s structure and suitability for biological environments.
Composition and processing conditions are the main adjustable factors identified for these properties. Changing the dissolved polymers or biomolecules, or altering how crosslinking occurs, can produce networks with different stiffness, pore structure, and degradation behavior. These variables allow researchers to tailor the hydrated material to the requirements of cell encapsulation, tissue engineering, or drug delivery.
The three approaches use different triggers to create the network: chemical reactions, physical interactions, or exposure to light. This distinction matters because the selected process influences how and where the solution solidifies. In particular, light-activated or otherwise controllable crosslinking can support formation in place, helping researchers shape a biomaterial around cells or within a target site.
A typical workflow begins by preparing a water-compatible polymer or biomolecule mixture with properties suited to the intended biological setting. Cells can then be positioned within the solution before the network forms, followed by activation of chemical, physical, or light-mediated crosslinking. The resulting hydrated structure holds the cells in a defined three-dimensional environment.
Researchers can use the approach when they need a hydrated, three-dimensional environment whose stiffness, porosity, and degradation can be adjusted. Its extracellular-matrix-like surroundings support tissue engineering and three-dimensional culture by organizing cells within a tunable material rather than a simple liquid setting. Formation in place also helps create shaped environments around cells or at target sites.
The same design principles extend to drug delivery and regenerative applications. Researchers can adjust the precursor composition and processing conditions to create a network suited to a particular biological purpose, while water retention maintains a hydrated setting. This combination of tunable structure and in-place solidification links material engineering with delivery systems, tissue development, and repair-oriented research.
