Stimuli-responsive smart materials that can undergo reversible chemical/physical changes under external stimuli such as mechanical stress, heat, light, gas, electricity, and pH, are currently attracting increasing attention in the fields of sensors, actuators, optoelectronic devices, information storage, medical applications, so forth. The current mostly concentrate on polymers, carbon materials, crystalline liquids, hydrogels, which have no or low structural order (i.e., responsive groups/moieties disorderly structures), inevitably introducing deficiencies a relatively response speeds, energy transformation inefficiencies, unclear structure-property relationships. Consequently, with well-defined regular molecular arrays offer new opportunity to create novel improved stimuli-responsive performance. Crystalline include framework (e.g., metal-organic frameworks, MOFs; covalent organic COFs) crystals molecules cages), obvious advantages compared amorphous materials. For example, be uniformly installed skeleton crystal form ordered arrays, making transfer between external-stimulus signals sites much faster more efficiently. Besides that, structures facilitate situ characterization their at level by means various techniques high-tech equipment spectra single-crystal/powder X-ray diffraction, thus benefiting investigation understanding mechanism behind behaviors Nevertheless, some unsolved challenges remain for (CSMs), hampering fabrication material systems practical applications. instance, materials' crystallinity increases, processability properties usually decrease, unavoidably hindering application.

Architecting polyelectrolyte hydrogels with Cu-assisted polydopamine nanoparticles for photothermal antibacterial therapy

Materials Today Bio, Journal Year: 2022, Volume and Issue: 15, P. 100264 - 100264

Published: April 20, 2022

Polydopamine nanoparticles (PDA NPs) are an appealing biomimetic photothermal agent for antibacterial treatment because of their long-term safety, excellent photostability, accessible manufacturing, and good biodegradability. However, the low conversion efficiency (PCE) PDA NPs requires high-power near-infrared light irradiation, which severely restricts practical application. In this work, PDA@Cu were fabricated by growing Cu in situ on surface then introduced into a polyelectrolyte hydrogel precursor (cationic polyethyleneimine/anionic pectin, named as CPAP). The formulated platform possessed high PCE (55.4%), almost twice much pure (30.8%). Moreover, designed CPAP/PDA@Cu captured killed some bacteria electrostatic adsorption, helped enhance performance. As expected, formed that combined advantageous features (high PCE) CPAP matrix (inherent activity preventing aggregation) can efficiently kill both vitro vivo under help laser irradiation. Taken together, study offers promising strategy constructing facile safe PDA-based therapy.
