Novel Monoclonal Antibody Detects Small Aβ Oligomers More Sensitively Than Lecanemab in Alzheimer's Disease CSF, Serum and Culture Media

Annals of Neurology, EarlyView.
Objective Aqueously diffusible oligomers of the amyloid β‐protein (oAβ) are neurotoxic and play a role in neuronal dysfunction in Alzheimer's disease (AD). Accurate quantification of oAβ in brains and biofluids could be valuable for understanding and monitoring AD.

Miniaturized Conductometric Biosensor for Rapid Detection of TNF‐α in Saliva

Advanced NanoBiomed Research, EarlyView.
A miniaturized conductometric sensor detects TNF‐α at femtomolar levels with high selectivity. The device enables noninvasive testing using pooled human saliva and supports smartphone‐based, real‐time resistance readings. This portable biosensor offers a practical alternative for monitoring TNF‐α, providing new opportunities for diabetes and related ...

Construction of a CO2‐Fixing Compartment Using a Shape‐Transforming DNA Scaffold

Chemistry – A European Journal, EarlyView.
A shape‐transforming DNA scaffold encapsulates RuBisCO within a controllable, self‐contacting compartment that mimics the carboxysome. The scaffold switches between open and closed states, enabling direct comparison of identical enzyme populations in different microenvironments.

Photoelectrochemical Hydrogen Peroxide Production via Simultaneous Reduction and Oxidation Processes

Chemistry – A European Journal, EarlyView.
Hydrogen peroxide (H2O2) is an important chemical substance and also a promising carbon‐free clean fuel. The design of a sophisticated photoelectrochemical (PEC) reaction system enables the solar‐driven H2O2 production through simultaneous water oxidation and oxygen reduction processes (H2O2/H2O2‐PEC cells).

Magnetoresistive Evidence of Degeneracy in Nanomagnets Obtained by Electrodeposition Technique

Magnetism
Inspired in pyrochlore materials presenting residual entropy and featuring collective excitation behaving like emergent monopoles, geometrically frustrated arrays of nanomagnets, denominated artificial spin ices (ASIs), were proposed as an interesting ...

Identification of Natural and Artificial Modifications in DNA at the Nanometer Level

Journal of Raman Spectroscopy, EarlyView.
Short single‐ and double‐stranded DNA sequences with natural and artificial markers are examined at ambient conditions using TERS to identify and localize the labelled nucleobases. The differences between single‐ and double‐stranded DNA should provide clear experimental evidence of the extreme surface sensitivity of TERS.

3D Polymeric Nanonetworks: From Self‐Assembly to Advanced Fabrication

Macromolecular Materials and Engineering, EarlyView.
This review provides the first systematic cross‐method comparison of fabrication techniques for 3D polymeric nanonetworks. It evaluates five key strategies—block copolymer self‐assembly, hyper‐crosslinking, template‐assisted methods, 3D printing, and nanolithography—across critical metrics including resolution, throughput, scalability, and material ...

Seedling resistance and chemical defenses against Psylliodes chrysocephala: the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

Pest Management Science, EarlyView.
The cabbage stem flea beetle (Psylliodes chrysocephala) is a major pest of winter oilseed rape (Brassica napus). We tested B. napus and Sinapis alba seedlings for feeding resistance and underlying chemical defenses. S. alba was least damaged, while metabolite profiles revealed resistance‐linked compounds, highlighting breeding potential for insect ...

Electrical detection of emergent magnetization dynamics in artificial spin ice

APL Materials
Artificial spin ices (ASIs) consisting of 72 stadium-shaped magnetic tunnel junction (MTJ) cells arranged in a honeycomb lattice were fabricated. The magnetization state of each cell was electrically detected using magnetoresistance.
