Bistable Dual‐Responsive Azobenzene‐co‐PNIPAM Soft Microactuators via Two‐Photon Direct Laser Writing

Advanced Intelligent Systems, EarlyView.
This work shows the successful integration of intrinsic bistability into thermoresponsive soft microactuators, fabricated by two‐photon polymerization utilizing the (E)–(Z)‐isomerization of azobenzenes. The bistable behavior accounts for a reversible volume change of Azo_pNIPAM microactuators initiated by light irradiation, at constant ambient ...

Engineering Tertiary Lymphoid Structures: Nanomedicine, Bioengineering, and Biomaterials for Precision Immunotherapy

Advanced NanoBiomed Research, EarlyView.
This review explains how biomaterials and nanoparticles can be used to induce or modulate tertiary lymphoid structures (TLSs), which are ectopic immune hubs that form in nonlymphoid tissues during chronic disease and cancer. By comparing different methods, the article highlights design principles for modeling TLSs or recapitulating specific TLS ...

Decoding the Pathophysiology of Autoimmune Diseases—Mechanism, Triggers, and Nanotherapeutics: A Review

Advanced NanoBiomed Research, EarlyView.
This review highlights how autoimmune diseases arise from intertwined immunological, genetic, and environmental factors, emphasizing gut microbiota dysbiosis as a pivotal driver. It outlines emerging nanotechnology‐based strategies—such as liposomes, hydrogels, and polymeric nanoparticles—that enhance targeted drug delivery, minimize systemic toxicity,

Refining the Production Date of Historical Palestinian Garments Through Dye Identification

Heritage
The dyes used to produce two Palestinian garments from the British Museum’s collection attributed to the late 19th–early 20th century were investigated by high pressure liquid chromatography coupled with diode array detector and tandem mass spectrometry (

Aloe vera–Based Green Synthesis of Silver Nanoparticles With Characterization, Potent Antibacterial and Antioxidant Properties

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Green synthesis has emerged as a suitable alternative to the traditional method for manufacturing nanoparticles (NPs) as it provides a safer, sustainable, healthy, and environmental path for the NPs synthesis. Silver nanoparticles (AgNPs) were prepared using a green method with locally sourced Aloe vera leaf extract.

The Manufacture of Lake Pigments from Artificial Colours: Investigating Chemistry and Recipes in the First Book on Synthetic Dyes-Based Lakes

Heritage
In 1900, Francis Herbert Jennison’s book The Manufacture of Lake Pigments from Artificial Colours was published in London. In the early 20th century, the technical literature focussing on synthetic dyes mainly dealt with their use for dyeing. Conversely,

Synthesis and Characterization of Ag–Fe Bimetallic Nanoparticles and Nanocomposites (Alloys and Core–Shells) for Photocatalytic Degradation of Bromophenol Blue Dye Using Grewia optiva Leaf Extract

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Ag–Fe bimetallic nanoparticles (alloy and core–shell structures) were synthesized using Grewia optiva leaf extract through a green, phytochemical‐mediated approach. The effects of pH, temperature, extract concentration, and Ag:Fe molar ratio on nanoparticle formation were systematically optimized, enabling size‐controlled and morphologically ...

Polylimonene Improves the In Vivo Wound Healing Performance of Sodium Alginate‐Based Hydrogels

Journal of Applied Polymer Science, EarlyView.
An oligomer derived from orange peel essential oil incorporated into an alginate hydrogel was shown to be biocompatible and to exhibit a high capacity for in vivo incisional wound healing, as confirmed by experimental assays and mathematical models fitted to the data describing wound area reduction as a function of the dressing‐tissue contact time ...
