Chitosan‐Graft‐Gelatin Hydrogel Containing Bromothymol Blue as a Food Spoilage Indicator for Intelligent Food Packaging

Advanced Materials Interfaces, EarlyView.
A chitosan‐graft‐gelatin hydrogel, incorporating a pH‐responsive dye, bromothymol blue, as a colorimetric freshness indicator is introduced to monitor the spoilage of chicken breasts. The hydrogel indicates microbial activity, and the production of carbon dioxide due to deteriorating food freshness via a change in pH, and serves as a smart and visual ...

Nanoengineering of Chitosan Sponges Via Atomic Layer Deposition of ZnO for Water Remediation Technologies

Advanced Materials Interfaces, EarlyView.
Chitosan sponges are modified with ZnO through atomic layer deposition (ALD) to enhance water remediation. Characterization reveals the growth of defective ZnO, which improves the water stability of the sponges. The material's effectiveness is demonstrated through the removal of Direct Blue 78 dye and the photocatalytic degradation of Naproxen ...

Fast Prototyping and Ex Vivo Evaluation of Dissolvable Millineedle Patches Made by Solvent Casting from CO2 Laser Ablated Elastomer Molds

Advanced Materials Interfaces, EarlyView.
CO2 laser ablation, a fast, inexpensive, and reproducible method, is used to create flexible elastomer molds with millimeter‐long cavities for the fabrication of dissolvable polymer needles. Made from PVP, these milli‐needles achieve ≈560 µm penetration into porcine skin, demonstrating their potential for effective transdermal drug delivery.

A Systematic Study of Staphylococcus aureus Biofilm Formation on Thiol‐Ene Polymers: Toward the Development of Microfluidic Bacterial Biofilm Models

Advanced Materials Interfaces, EarlyView.
This work presents a systematic characterization of an emerging polymer platform, off‐stoichiometry thiol‐ene, in terms of its ability to support the formation, growth, and metabolic activity of Staphylococcus aureus biofilms. The findings indicate that thiol‐enes promote S.

Toward Personalized Stationary Chromatography Phases: Equipping Commercial Silica Phases with Selected Peptide‐Based Binding Domains to Tailor Affinity

Advanced Materials Interfaces, EarlyView.
The 7‐mer peptide motifs QFFLFFQ, QFFEFFQ, and QFQQSFF, known as good, medium, and poor binders for the photosensitizers m‐THPC and Chlorin E6 are covalently immobilized on commercial amino‐functionalized silica particles by inverse electron‐demand Diels‐Alder ligation.

Flexographic Printed Flexible Thermochromic Stickers for Smart Sensing Applications

Advanced Materials Interfaces, EarlyView.
Thermochromic complexes of 1‐butyl‐3‐methylimidazolium chloride and 4‐chloronickelate are synthesized and incorporated in hydroxypropyl cellulose‐based water inks. Films with 40 wt.% thermochromic complexes and three layers are flexographic printed on polypropylene tags in a process compatible with roll‐to‐roll manufacturing. After encapsulation with a

Self‐Supporting Graphene Foam for the Removal of Chlorine from Water

Advanced Materials Interfaces, EarlyView.
Graphene‐based porous materials are promising for sorption and catalysis but often require binders. This study presents a self‐supporting graphene foam made from graphene oxide and hydrazine vapor. Structural, mechanical, and functional analyses confirm its superior chlorine removal efficiency (97%) and reusability, outperforming activated carbon in ...
