Precise Synthesis of High-Strength Chiral Au Nanomaterials: From Chiral Au Nanoclusters to Chiral Au Nanoparticles

Inorganics, Journal Year: 2025, Volume and Issue: 13(3), P. 72 - 72

Published: Feb. 27, 2025

Chiral gold nanomaterials have promising applications in biomedicine, catalysis, optics and other fields. However, the complexity of their chiral sources has led to many challenges terms functional design controlled synthesis. In this paper, we systematically review development history Au nanomaterials; deeply analyze synthesis strategy, construction mechanism, performance optimization pathway; discuss formation mechanism light progress cutting-edge research look into future direction development. The aim is provide theoretical methodological support for controllable nanomaterials.

Synthesis of [Ni₂₃Se₁₂X₃(PEt₃)₁₀] (X = Br, I) via Post-synthetic Modification

Inorganic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 3, 2025

Treatment of [Ni23Se12Cl3(PEt3)10] (1-Cl) with excess Me3SiX (X = Br, I) results in formation [Ni23Se12X3(PEt3)10] 1-Br; X I, 1-I) good yields. 1-Br and 1-I are exceptionally rare examples atomically precise nickel nanoclusters (APNCs). Both were characterized by X-ray crystallography, NMR spectroscopy, ESI-mass spectrometry. clusters feature a compact [Ni13]7+ kernel capped [Ni10(μ-Se)9X3]- shell. Cluster could also be isolated cleanly using bottom-up synthetic approach, via reaction [Ni(1,5-cod)2] PEt3 SePEt3 [NiBr2(PEt3)2]. Under these conditions, it 43% yield. In contrast, [NiI2(PEt3)2] [Ni3(μ3-Se)2I2(PEt3)4] (2-I) as the only isolable product. These highlight challenges inherent synthesis Ni nanoclusters, demonstrate value postsynthetic modification 3d metal APNCs.

A Portable Electrochemical Biosensor Based on an Amino-Modified Ionic Metal–Organic Framework for the One-Site Detection of Multiple Organophosphorus Pesticides

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 3, 2024

Constructing stable, portable sensors and revealing their mechanisms is challenging. Ion metal-organic frameworks (IMOFs) are poised to serve as highly effective electrochemical for detecting organophosphorus pesticides (OPs), leveraging unique charge properties. In this work, an amino-modified IMOF was constructed combined with near-field communication (NFC) technology develop a portable, touchless, battery-free biosensor
