Thermoresponsive Hydrogel‐Enabled Thermostatic Photothermal Therapy for Enhanced Healing of Bacteria‐Infected Wounds

Advanced Science, Год журнала: 2023, Номер 10(11)

Опубликована: Фев. 12, 2023

Abstract Photothermal therapy (PTT) has emerged as an attractive technique for the treatment of bacterial infections. However, uncontrolled heat generation in conventional PTT inevitably causes thermal damages to healthy tissues and/or organs. It is thus essential develop a smart and universal strategy regulate photothermal equilibrium temperature preset safe threshold. Herein, thermoresponsive hydrogel‐enabled thermostatic system enhanced healing bacteria‐infected wounds reported. In this system, near‐infrared (NIR)‐triggered by nanomaterials spontaneously transferred hydrogel with lower critical solution (LCST), leading its rapid phase transition forming considerable light‐scattering centers block NIR penetration. Such dynamic reversible process automatically regulates phase‐transition point LCST‐type hydrogel. contrast temperature‐uncontrolled severe damages, provides effective protection on organs, which remarkably accelerates wound efficient eradication. This study establishes smart, simple platform, holding great promise skin

Fundamentals and Advances in Stimuli-Responsive Hydrogels and Their Applications: A Review

Gels, Год журнала: 2025, Номер 11(1), С. 30 - 30

Опубликована: Янв. 2, 2025

This review summarizes the fundamental concepts, recent advancements, and emerging trends in field of stimuli-responsive hydrogels. While numerous reviews exist on this topic, continues to evolve dynamically, certain research directions are often overlooked. To address this, we classify hydrogels based their response mechanisms provide an in-depth discussion key properties mechanisms, including swelling kinetics, mechanical properties, biocompatibility/biodegradability. We then explore hydrogel design, synthesis, structural engineering, followed by overview applications that relatively well established from a scientific perspective, biomedical uses (biosensing, drug delivery, wound healing, tissue engineering), environmental (heavy metal phosphate removal environment polluted water), soft robotics actuation. Additionally, highlight unconventional such as local micro-thermometers cell mechanotransduction. concludes with current challenges future prospects field, aiming inspire further innovations advancements bring them closer societal needs.

Designing Hybrid Plasmonic Superlattices with Spatially Confined Responsive Heterostructural Units

Nano Letters, Год журнала: 2025, Номер unknown

Опубликована: Янв. 3, 2025

Plasmonic superlattices enable the precise manipulation of electromagnetic fields at nanoscale. However, optical properties static lattices are dictated by their geometry and cannot be reconfigured. Here, we present a surface-interface engineered plasmonic superlattice with confined polyelectrolyte-functionalized metal–organic framework (MOF) hybrid layers to tune plasmon resonance for ultrafast chemical sensing. The surface lattice frequency in visible spectrum was achieved using electron-beam lithography humidity-responsive polyelectrolyte brush grafted onto thiol-initiator-modified gold nanoparticle through atom transfer radical polymerization. An MOF thin film assembled on via layer-by-layer immersion. Surface observed without additional matched dielectric environment around NPs, tuned adjusting thickness refractive index layer. Furthermore, high sensitivity response were due coherence between MOFs polymer layers.
