Nano‐ and Micro‐Sized Solid Materials Used as Antiviral Agents

open access: yesAdvanced Functional Materials, EarlyView.
Due to the rise of viral infections in humans and possible viral outbreaks, the use of nano‐ or micro‐sized materials as antiviral agents is rapidly increasing. This review explores their antiviral properties against RNA and DNA viruses, either as a prevention or a treatment tool, by delving into their mechanisms of action and how to properly assess ...

Temperature‐Induced Nonvolatile Switching through Thermal Hysteresis in a Gd3Fe5O12/Ho3Fe5O12 Exchange‐Coupled Rare‐Earth Iron Garnet Bilayer

open access: yesAdvanced Functional Materials, EarlyView.
Reducing power consumption in spintronic memory remains a major challenge due to the need for high current densities. A bilayer of gadolinium and holmium iron garnets enables purely temperature‐induced, nonvolatile magnetic switching with bistable states within a ±25 K range. This approach achieves up to 66‐fold lower energy use than current spin–orbit

Overcoming Debye Length Limitations in Electrolyte‐Gated Transistor Biosensors Using Nanoscale‐Grooved Oxide Semiconductors Fabricated by Thermal Nanoimprint Lithography

open access: yesAdvanced Functional Materials, EarlyView.
Nanoscale‐grooved indium gallium oxide (IGO) semiconductors, patterned via thermal nanoimprint lithography (NIL) using CD/DVD templates, are integrated into electrolyte‐gated transistor biosensors to overcome Debye length limitations. Precisely engineered concave–convex nanostructures modulate local electrostatic potentials, extend the effective Debye ...

External Reflection From Two‐Photon Laser‐Printed Micromirrors Enables Photomechanical Actuation at a 90° Incident Angle

open access: yesAdvanced Functional Materials, EarlyView.
Light reflectance increases along incidence angle and transmittance significantly drops around 90‐degree incidence angle. Here, we report two‐photon laser printed micro mirrors that redirect the skimming light beam into normal light absorption. Using this technique, light‐driven micro walkers and grippers are demonstrated by using grazing incidence ...

Bio‐Inspired Magnetically Tunable Structural Colors from Elliptical Self‐Assembled Block Copolymer Microparticles

open access: yesAdvanced Functional Materials, EarlyView.
Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.

Carbon Contacts to Proteins Enable Robust, Biocompatible Electronic Junctions with Near‐Activation‐less Conduction Down to 10 K

open access: yesAdvanced Functional Materials, EarlyView.
A robust solid‐state protein junction with a semi‐transparent eC/Au electrode allows photoexcitation of the bacterio‐rhodopsin, bR layer, to isomerize the bR retinal. The resulting photo‐response shows the protein is functional in the solid‐state junction.

Actuating and Sensing Composites of Liquid Crystal Elastomers and Poly(ionic liquid)s

open access: yesAdvanced Functional Materials, EarlyView.
Ionic conductive, mechanically tough, flexible, and stretchable filaments of a composite material comprising a liquid crystal elastomer and a poly(ionic liquid) are produced through 3D printing, which exhibit large actuation strain under stimulation and electrical resistance variation in response to deformation or environmental condition changes. Their

Breathable Graphene Oxide‐Polymer Composite Membranes With Two‐Step Barrier Mechanism Against Nerve Agents

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Breathable membranes that reject chemical warfare agents (CWAs) are required for next‐generation protective apparel. A dual‐function graphene oxide (GO)‐polyamine architecture is introduced that addresses the long‐standing tradeoff between vapor transmission and CWA selectivity.
