Functional Polymer‐Engineered Magnetic Nanoparticles as Dual‐Modal Theragnostic Probes for Early Alzheimer's Disease Detection and Therapy

Advanced NanoBiomed Research, EarlyView.
The nanoparticle consists of a 3 nm iron oxide core functionalized with an amphiphilic polymer coating containing Aβ‐targeting DSA moieties and biocompatible PEG chains. This design supports measurable transport in a BBB‐related model and specific interaction with Aβ species, while providing MRI contrast enhancement for diagnosis and therapeutic ...

Record Dissymmetry in Vibrational Optical Activity: Combining Vibronic Coupling and Aggregation in Cobalt(II) Camphorate Complexes

Angewandte Chemie, EarlyView.
The cobalt(II) bis(trifluoroacetylcamphorate) scaffold exhibits versatile coordination chemistry with solvent‐driven ligand exchange and geometrical rearrangements, associated with unique chiroptical properties. Microcrystalline suspension of [Co(tfc)2(CH3CN)2] revealed the largest VCD dissymmetry factor ever reported (g ≈ 0.2 at 1600 cm−1), arising ...

Metal Oxides Catalyze Formation of Dehydroamino Acids by Phosphate β‐Elimination Under Physiological Conditions

Angewandte Chemie, EarlyView.
Dehydroamino acids (DHAA) are atypical electrophilic sites that lead to crosslinked proteins in Alzheimer's disease (AD) brains. No catalyst for their formation has been known in humans. We report that metal oxides catalyze β‐elimination of phosphoserine and phosphothreonine in model peptides at pH 7.5°C and 37°C, yielding DHAAs.
