Light‐Activated Micromotors in Air Propelled by Thermal Convection

Advanced Materials, EarlyView.
Near‐infrared‐driven micromotors in air can overcome gravity and generate convective motion by a light‐induced thermal mechanism driven by a temperature gradient in the air caused by the interaction of the gold nanoparticles present on the surface of ZnO and NIR irradiation.

Genetic Surfaceome E. coli Reprogramming Enables Selective Water Oxidation

Advanced Materials, EarlyView.
A novel enzymatic material based on bilirubin oxidase (BOD) surface‐expressed on E. coli for effective electrocatalysis is reported. With this material, highly efficient and selective water oxidation is achieved, a critical half reaction for synthetic photosynthesis. Abstract Programming catalytic behavior at the microbial genome level is a frontier in

Tuning the Surface State and Zeta Potential of Aged CuO Nanoparticles by Additive‐Free Surface Treatments as Guided by XPS

Advanced Materials, EarlyView.
Aging of CuO nanoparticles (NP) involves a surface reconstruction induced by hydroxylation and concurrent organic‐O adsorption, which introduces O defects in the NP subsurface region. The defective surface results in a diffuse surface space region, as reflected by a low ζ‐potential of the aged NPs in ethanol solvent.

Lithium‐Charged Gold Nanoparticles: A New Powerful Tool for Lithium Delivery and Modulation of Glycogen Synthase Kinase 3 Activity

Advanced Materials, EarlyView.
This study introduces glutathione‐stabilized gold nanoparticles for targeted lithium delivery (LiG‐AuNPs), enabling the controlled modulation of Glycogen Synthase Kinase‐3 (GSK‐3β). These non‐toxic, 2‐nm particles release lithium intracellularly, effectively inhibiting GSK‐3β in the brain without significant plasma lithium alterations.

Physical Adsorption‐Driven Assembly of Au‐Locked Nucleic Acid (LNA) Probes on MoS2 Nanosheets for SERS‐Based Detection of microRNAs (miRNAs)

Advanced Materials Interfaces, EarlyView.
The Au‐LNA Raman probe, composed of gold nanoparticles (AuNPs), thiol functional group, and Cy3 modified LNAs, synthesized after hybridization of LNA and miR‐210‐3p target, is integrated into the MoS2@Au composite. The integration of the nanocomposite is formed by physical adsorption of Au‐LNA nanohybrid with MoS2. Characterization confirms morphology,

Fabrication of Multimodal Anion Exchange Membrane for Chromatographic Purification of Full Adeno‐Associated Viral Capsids

Advanced Materials Interfaces, EarlyView.
A novel multi‐modal anion exchange membrane (MMAEX) is successfully fabricated for separating empty and full AAV2 capsids. The functionalized membrane has an average pore size of 0.5 µm and exhibits both charge and hydrophobic functionality. A full capsid recovery of 72.9% at 85.3% purity with gradient elution, or 70.3% recovery at 92.2% purity with ...

An Injection‐Molded Modified Silicone Rubber for Cancer‐on‐Chip Applications

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This study describes the characterization and application of an injection‐molded functionalized PDMS fluidic insert for the commercially available Micronit system. Modified PDMS can accommodate cell culture and is able to covalently bind proteins for long‐lasting coatings under flow‐conditions.

Thermal Annealing Enhances Piezoelectricity and Regenerative Potential of PVDF‐TrFE Nanofiber Scaffolds

Advanced Materials Technologies, EarlyView.
Thermal annealing improves the structure, stiffness, and piezoelectric properties of poly(vinylidene flouride‐trifluoroethylene) (PVDF‐TrFE) nanofiber scaffolds. These annealed scaffolds promote Schwann cell proliferation and matrix remodeling in vitro and demonstrate in vivo biocompatibility.

Smart Sampling Capsule for Capture and Detection of Enteric Pathogens in the Small Intestine

Advanced Materials Technologies, EarlyView.
An ingestible smart sampling capsule for capturing asymptomatic enteric pathogens at their primary sites of interaction within the small intestine. This capability enables non‐invasive detection of early pathogen colonization within the gut environment prior to fecal shedding, providing a robust approach for pathogen surveillance and microbiome studies.
