2025
This video demonstrates the crosslinking of neuronal surface proteins using Bis-sulfosuccinimidyl suberate or BS3. Isolated and chilled mouse brain is sectioned coronally. The desired region is extracted from the sections, minced, and treated with BS3. BS3 crosslinks surface proteins like GABA receptors, leaving internal proteins unaltered. The reaction is quenched with glycine before processing the samples for further analysis.

This article describes a process for tuning the size and crosslinking density of covalently crosslinked nanoparticles from linear polyesters containing pendant functionality. By tailoring synthesis parameters (polymer molecular weight, pendant functionality incorporation, and crosslinker equivalents), a desired nanoparticle size and crosslinking density can be achieved for drug delivery applications.

FAQs
Stability depends on a distributed network of reversible or noncovalent connections rather than permanent covalent bonds. Hydrogen bonding, ionic interactions, hydrophobic association, crystallization, molecular entanglement, and reversible assembly can each contribute to cohesion. The relative contribution of these mechanisms affects whether the scaffold behaves as a stable structure, a dynamic network, or a material capable of gradual remodeling.
Compared with covalently crosslinked scaffolds, non-chemically crosslinked systems emphasize reversibility and formation under relatively mild conditions. Their physical interactions can reorganize as the material changes, which may support remodeling or degradation. This distinction matters when cells or therapeutic components could be affected by harsher chemical conditions, although the resulting dynamic behavior makes structural performance dependent on material organization.
Mechanical behavior is linked to more than the presence of a three-dimensional network. The type and balance of physical interactions, along with material organization, influence scaffold mechanics, porosity, and dynamic behavior. Those properties shape how cells attach and migrate and how tissue develops. Consequently, changing the network-forming mechanism can alter biological performance without changing the scaffold’s overall purpose.
Design begins by matching the desired biological role with the scaffold’s physical behavior. For tissue support, researchers consider mechanics and porosity; for therapeutic delivery, they also consider stability and the ability of the network to reorganize or degrade. The selected interaction mechanism and material organization then determine whether the construct favors persistent support, cellular remodeling, or dynamic delivery performance.
In tissue engineering and regenerative medicine, these scaffolds provide a three-dimensional environment in which cells can attach, migrate, and contribute to tissue development. Their adjustable mechanics and porosity help researchers relate scaffold structure to biological behavior, while dynamic interactions may permit remodeling as the construct changes. The approach is relevant when structural support must coexist with evolving cell and tissue organization.
For therapeutic delivery, the network’s physical organization can provide a scaffold-like matrix around biologically sensitive components. Formation under relatively mild conditions may help preserve those components, while reversible interactions and degradation behavior influence how the material changes over time. The central design challenge is balancing sufficient structural stability with a dynamic network suited to the delivery context.
