Natural Aging of Biomaterials in Ambient and Physiological Environments

Advanced NanoBiomed Research, EarlyView.
Biomaterials used in biomedical applications can change their physical properties over time, even under ambient and physiological conditions. This review highlights key studies on the natural aging of materials ranging from soft hydrogels to metals and ceramics, emphasizing how time‐dependent changes influence function and performance.

Multi‐Responsive Bowl‐Shaped Janus Nanomotors Based on Polyitaconic acid/Polypyrrole on the Surface of Iron Oxide Nanoparticles with Chemical, Electrical, and Magnetic Field Actuation for Targeted Drug Delivery Applications

Advanced NanoBiomed Research, EarlyView.
Bowl‐shaped Janus nanomotors with platinum, iron oxide, and polypyrrole integrate catalytic, magnetic, and electric propulsion for targeted drug delivery. They demonstrate controlled, directional motion under varying pH and hydrogen peroxide conditions, with optimal performance in neutral media.

Thermally Controlled Chiral Supramolecular Polymorphism in Water

Angewandte Chemie International Edition, EarlyView.
Using an amphiphilic oligo(phenyleneethynylene) derivative, we establish LCST‐coupled chirality as a strategy to regulate thermoresponsive supramolecular polymorphism in water. At room temperature, AggI forms discrete assemblies that transform into elongated helical fibers (AggII) near the LCST and subsequently to sheet‐like structures (AggIII) at ...

MagNanoTrap Enrichment Empowers Ultra‐Sensitive Quantification of Mixed Nanoplastic Particles From Environmental Water Samples

Angewandte Chemie International Edition, EarlyView.
Fe3O4 nanoparticles coated with the bifunctional peptide LCI‐DZ‐MBP1, where LCI binds the iron oxide surface and MBP1 acts as a universal plastic‐binding peptide, combined with pyrolysis‐gas chromatography/mass spectrometry (Py‐GC/MS), enable efficient enrichment, precise detection, and quantification of mixed plastics (PS, PE, PP, PET, PMMA, PC, Nylon

Harnessing the Interfacial Activity of Soluble Faba Protein‐Tannic Acid Conjugates for Enhanced Lipid Oxidative Stability of Oil‐in‐Water Emulsions

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT In oil‐in‐water emulsions, lipid oxidation begins at the interface between the two phases. One strategy to slow down this process is to place antioxidants at the interface, where they can directly block oxidative reactions. This study explored that idea by conjugating soluble faba bean protein with tannic acid using the free‐radical grafting ...

Directed Charge Transfer‐Driven Efficient Photocatalytic Hydrogen Production in Dual S‐Scheme WS2/Co9S8/ZnCdS Heterojunction

Carbon Energy, EarlyView.
The photocatalytic hydrogen evolution reaction (HER) activity of the polyoxometalate (POM)‐derived dual S‐scheme heterojunction photocatalyst WS2/Co9S8/ZnCdS reaches a value as high as 15.66 mmol g−1 h−1 under visible light (λ ≥ 420 nm), providing a straightforward approach for the development of dual S‐scheme heterojunctions to enhance the efficiency ...

Light sheet fluorescence microscopy

Nature Reviews Methods Primers, 2021
Light sheet fluorescence microscopy (LSFM) uses a thin sheet of light to excite only fluorophores within the focal volume. Light sheet microscopes (LSMs) have a true optical sectioning capability and, hence, provide axial resolution, restrict photobleaching and phototoxicity to a fraction of the sample and use cameras to record tens to thousands of ...

Practical considerations for quantitative light sheet fluorescence microscopy

Nature Methods, 2022
Fluorescence microscopy has evolved from a purely observational tool to a platform for quantitative, hypothesis-driven research. As such, the demand for faster and less phototoxic imaging modalities has spurred a rapid growth in light sheet fluorescence microscopy (LSFM).
