Anti-tumor therapy through high ROS performance induced by Ag nanoenzyme from boron cluster with halloysite clay nanotubes.

The conventional silver nanoparticles (Ag NPs) are characterized with high loading rate and stacking phenomenon, leading to shedding caused biotoxicity and low catalytic efficiency. This seriously hinders their application in biomedicine. Here, we modified the highly dispersible Ag NPs and Ag single-atoms (SAs) synthesis by combining the halloysite clay nanotubes (HNTs) and dodecahydro-dodecaborate (closo-[BH]) to increase the biocompatible properties and decrease the loading rate.

Platinum group nanoparticles doped BCN matrix: Efficient catalysts for the electrocatalytic reduction of nitrate to ammonia.

The effective treatment of nitrate (NO) in water as a nitrogen source and electrocatalytic NO reduction to ammonia (NH) (NRA) have become preferred methods for NO-to-NH conversion. Achieving efficient NO-to-NH conversion requires the design and development of electrode materials with high activity and efficiency for the electrocatalytic NRA reaction. Herein, based on the special properties of dodecahydro-closo-dodecaborate anions, a BCN matrix, loaded with platinum-group nanoparticles (namely, Pd/BCN, Pt/BCN, and Ru/BCN), was prepared using a simple method for the electrocatalytic NRA reaction.

Applications of Boron Cluster Supramolecular Frameworks as Metal-Free Chemodynamic Therapy Agents for Melanoma.

Chemodynamic therapy (CDT) is a highly targeted approach to treat cancer since it converts hydrogen peroxide into harmful hydroxyl radicals (OH·) through Fenton or Fenton-like reactions. However, the systemic toxicity of metal-based CDT agents has limited their clinical applications. Herein, a metal-free CDT agent: 2,4,6-tri(4-pyridyl)-1,3,5-triazine (TPT)/ [closo-B H ] (TPT@ B H ) is reported.

Synthesis, Structure, and Properties of Complexes Based on 2,4-Bis-(triazol-1-yl)benzoic Acid as a Ligand.

Using 2,4-bis-(triazol-1-yl)-benzoic acid as the main ligand and terephthalic acid (TPA) as the auxiliary ligand, combined with Cd(NO)·4HO and Zn(NO)·6HO, self-assembly under solvothermal conditions gave three novel complexes: [Cd(L)(HO)] (), [Cd(L)(TPA)(HO)]·HO (), and [Zn(L)(TPA)]·HO () (TPA = terephthalic acid). The crystal structure test showed that complex belongs to the triclinic crystal system and the 1̅ space group and complexes and belong to the monoclinic crystal system and the 2/ space group. Solid-state fluorescence experiments show that complexes , , and all have excellent optical properties: among them, complexes and can selectively detect MnO with low detection limits (0.
