Biomineralization of the extracellular matrix is an essential, regulated process. Inappropriate mineralization bone and vasculature has devastating effects on patient health, yet integrated understanding chemical cell biological processes that lead to mineral nucleation remains elusive. Here, we report biomineralization associated with poly(ADP-ribose) synthesized by polymerases in response oxidative and/or DNA damage. We use ultrastructural methods show can form both calcified spherical...
Abstract Attempts to rationally tune the macroscopic mechanical performance of supramolecular hydrogel networks through noncovalent molecular interactions have led a wide variety materials with desirable functions. While viscoelastic properties are dominated by temporal hierarchy (crosslinking kinetics), direct mechanistic studies on spatiotemporal control networks, based host–guest chemistry, not yet been established. Here, assembled from highly branched cucurbit[8]uril‐threaded...
