Amphotericin B (AmB) has been the first-line treatment for visceral leishmaniasis (VL), a neglected protozoan disease, especially in regions like Bihar, India, where resistance to antimonials is widespread. However, adverse drug reactions are a major limiting factor. We evaluated a novel formulation of AmB conjugated to amine-modified graphene (f-Gr) for safety and efficacy over conventional Am...

The nanopore sensor as a high-throughput and low-cost technology can detect single nanoparticle in solution. In the present study, the silicon nitride nanopores were fabricated by focused Ga ion beam (FIB), and the surface was functionalized with 3-aminopropyltriethoxysilane to change its surface charge density. The positively charged nanopore surface attracted negatively charged nanoparticles ...

The effective chemical modification and self-assembly of diamond-based hierarchical composite materials are of key importance for a broad range of diamond applications. Herein, we report the preparation of novel core-shell diamond-based nanocomposites for dye adsorption toward wastewater treatment through a layer-by-layer (LbL) assembled strategy. The synthesis of the reported composites began ...

Herein, we report the simple preparation of water dispersible angular-shaped amine-functionalized superparamagnetic iron oxide nanoparticles (A-SPIONs). A-SPIONs were synthesized by heating iron(III) acetylacetonate in a mixture of solvents containing polyethyleneglycol (PEG) and branched polyethyleneimine (b-PEI) under vigorous stirring. Both PEG and b-PEI provided high water dispersibility by...

Abstract We present a mechanistic study on the formation and dynamic changes of ligand‐based heterogeneous Pd catalyst for chemoselective hydrogenation α,β‐unsaturated aldehyde acrolein. Deposition allyl cyanide as precursor ligand layer renders highly active close to 100 % selective toward propenol by promoting acrolein adsorption in desired configuration via C=O end. Employing combination rea...

Using a three-phase system, centimeter-scale monolayer gold nanoparticle (Au NP) films have been prepared that have long-range order and hydrophobic ligands. The system contains an interface between an aqueous phase containing Au NPs and an oil phase containing one of various types of amine ligands, and a water/air interface. As the Au NPs diffuse to the water/oil interface, ligand exchange tak...

in this study, kinetics and mechanism of the sulfur dioxide adsorption on the single-walled carbon nanotubes (cnt) are investigated. three single-walled carbon nanotubes, including the armchair (6,6), chiral (6,5) and zigzag (6,0) cnts were chosen as the models and the different orientations of so2 molecule relative to the cnt axis were considered. the b3lyp functional within the 6-31g(d) basis...

Selective nucleophilic substitution on a perfluorophenyl unit comprising a BODIPY fluorophore using an alkanethiol or a primary amine offers a quantitative fluorophore labelling strategy, while retaining high photostability and emission quantum yields approaching unity.

Introduction: Carbon nanotubes (CNTs) have shown enormous potential in neuroscience. Nerve growth factor (NGF)-CNTs complex promotes the neuronal growth, however, the underlying mechanism(s) have remained elusive. Based on the interplay between NGF and the endocannabinoid system, involvement of the neuroprotective endocannabinoid, 2-arachidonoyl glycerol (2-AG), was investigated in the mechanis...

While the use of visible light to drive chemical reactivity is of high importance to the development of environmentally benign chemical transformations, the concomitant use of a stoichiometric electron donor or acceptor is often required to steer the desired redox behavior of these systems. The low-cost and ubiquity of tertiary amine bases has led to their widespread use as reductive additives ...
