Colloidal gold nanoparticles (AuNPs) functionalised with hydrophilic thiols can be used as drug delivery probes, thanks to their small size and character. AuNPs possess unique properties for use in nanomedicine, especially cancer treatment, diagnostics therapeutic tools. Thiol were synthesised loaded methotrexate (MTX). Spectroscopic morphostructural characterisations evidenced the stability of colloids upon interaction MTX. Solid state (GISAXS, GIWAXS, FESEM, TEM, FTIR-ATR, XPS) dispersed...
Abstract Amino and sulfonate ending groups thiols are used as functionalizing agents to stabilize of gold nanoparticles (AuNPs), obtaining hydrophilic AuNPs with a 10–20 nm diameter range tunable surface charge. The nanomaterial is extensively characterized from physicochemical point view by UV–Vis Fourier‐transform infrared spectroscopy, nuclear magnetic resonance (NMR) synchrotron radiation X‐ray photoelectron spectroscopy (XPS), dynamic light scattering investigate the bonding between two...
Nanomaterials such as gold nanoparticles employed solid-state sensors have attracted attention in recent years due to their ability detect poisonous elements the indoor/outdoor environment. Herein, chemoresistive based on (AuNPs) functionalized with mixed thiol ligands were tested sensing materials. Specifically, electrical response of nanoparticles-based was against Hg0vap, H2S, SO2, NH3, and relative humidity (RH) at room temperature. Gold samples synthesized by wet reduction method then...
The detection of a photoacoustic signal allows listening to both absorption and scattering phenomena generated by three-dimensional self-assembled super-aggregates. Quantitative size filling factor morpho-parameters was extrapolated spectra.
Abstract The preparation of three different functionalized palladium nanoparticles (PdNPs) systems for room temperature BTX (benzene, toluene, p‐xylene) sensing detection and their morphostructural characterization is described. PdNPs are prepared through a two‐phase water/toluene wet chemical reduction method in the presence bifunctional organic thiols as stabilizing agents suitable formation covalently linked networks: p ‐terphenyl‐4,4″‐dithiol (PdNPs‐TR), biphenyl‐4,4′‐dithiol (PdNPs‐BP),...
Abstract Rod‐like organometallic dithiol containing square‐planar Pt(II) centers, i. e ., trans,trans ‐[(H 3 COCS)Pt(PBu ) 2 (C≡C−C 6 H 4 −C −C≡C)(PBu Pt(SCOCH )] was used as bifunctional stabilizing agent for the synthesis of Pd‐, Au‐, and AgNPs (MNPs). All MNPs showed diameters about nm, which can be controlled by carefully modulating parameters. Covalent stabilization occurred through a single S bridge between noble metal nanocluster surfaces, leading to network regularly spaced NPs with...
Acrylates-based co-polymeric nanoparticles (PNPs) are widely used in nanomedicine applications due to their tunable hydrophilic surface, physical and chemical versatility. Particularly attracting is use as nanocarriers for imaging agents. Herein, methyl methacrylate (MMA) N,N-dimethylacrylamide (DMAA) monomers were synthesize p(MMA-co-DMAA) the 200–600 nm size range via surfactant-free radical emulsion polymerization technique. Different MMA/DMAA molar ratios, temperatures, reaction times...
