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.

To study the effects of Aβo in vivo, we developed a model based on repeated hippocampal infusions of soluble Aβo coupled with continuous infusion of Aβo antibody (6E10) in the hippocampus using osmotic pumps to counteract the neurotoxic effect of Aβo.
FAQs
The timing and extent of polymer crosslinking determine how the infused material develops its three-dimensional network. Temperature, pH, ionic conditions, or a chemical reaction can trigger this transition. Because these variables influence when the precursor changes state, they are central to controlling placement, retention, and the resulting support within biological tissue.
Once formed, the network retains substantial water and creates a hydrated local environment. That combination helps the material occupy or support irregular tissue spaces while maintaining conditions in which cells can interact with the surrounding matrix. The biological value therefore depends not only on where material is delivered, but also on how the network behaves afterward.
Hydrogel Infusion can localize therapeutic agents by keeping them within the polymer network near the treatment site. This localized retention may support controlled release rather than immediate dispersal, while the hydrated matrix provides the surrounding environment. Such behavior is relevant when treatment aims to combine material placement with delivery of an agent.
A basic workflow begins with delivering a liquid hydrogel precursor into or around the selected tissue, followed by formation of the network through an appropriate crosslinking trigger. The relevant trigger may be thermal, pH-dependent, ionic, or chemical. This sequence allows the material to form after delivery and occupy the target site's available space.
Medical research examines this approach across drug delivery, wound management, tissue engineering, regenerative therapies, and minimally invasive treatment strategies. The same infusion concept can therefore serve different goals: retaining a therapeutic agent, filling an irregular tissue space, creating local support, or providing a hydrated setting for cell interactions.
For drug delivery, attention centers on retaining agents and supporting controlled release. In wound management, tissue engineering, and regenerative therapies, the emphasis shifts toward localized support, filling irregular spaces, and creating a hydrated environment for cell interactions. Minimally invasive strategies add the value of forming the network after the precursor reaches the target.
