Accelerated SelfHealing Via Ternary Interpenetrating Microvascular Networks
Self-healing materials with dual interpenetrating microvascular networks enable two-part healing chemistries and repeated healing of damage in a localized region. [ 1 ] However, due to slow healing kinetics, multiple days are required between damage events to recover mechanical performance under ambient conditions. By directly writing a third interdigitated microvascular network within these ep...
متن کاملAntifungal hydrogels.
Fungi are increasingly identified as major pathogens in bloodstream infections, often involving indwelling devices. Materials with antifungal properties may provide an important deterrent to these infections. Here we describe amphogel, a dextran-based hydrogel into which amphotericin B is adsorbed. Amphogel kills fungi within 2 h of contact and can be reused for at least 53 days without losing ...
متن کاملTemplating hydrogels
Templating processes for creating polymerized hydrogels are reviewed. The use of contact photonic crystals and of non-contact colloidal crystalline arrays as templates are described and applications to chemical sensing and device fabrication are illustrated. Emulsion templating is illustrated in the formation of microporous membranes, and templating on reverse emulsions and double emulsions is ...
متن کاملSupramolecular Photoactivatable Anticancer Hydrogels.
A photoactivatable dopamine-conjugated platinum(IV) anticancer complex (Pt-DA) has been incorporated into G-quadruplex G4K+ borate hydrogels by using borate ester linkages (Pt-G4K+B hydrogel). These were characterized by 11B NMR, attenuated total reflection Fourier transform infrared spectroscopy, circular dichroism, scanning electron microscopy and transmission electron microscopy. Microscopy ...
متن کاملHypoxia-Inducible Hydrogels
Oxygen is vital for the existence of all multicellular organisms, acting as a signalling molecule regulating cellular activities. Specifically, hypoxia, which occurs when the partial pressure of oxygen falls below 5%, plays a pivotal role during development, regeneration and cancer. Here we report a novel hypoxia-inducible (HI) hydrogel composed of gelatin and ferulic acid that can form hydroge...
