Lanthanide complexes with organic ligands exhibit unique photophysical properties, including long-lived emission lifetimes, large Stokes shifts, and sharp bands, making them highly attractive for bioanalytical biomedical applications. Incorporating these into nanoparticles can further enhance signal intensity assay sensitivity in both vitro vivo settings. Here, we report the first successful use of desolvation method to synthesize bovine serum albumin (BSA) loaded europium complexes. This...
The present work demonstrates the optimization of ligand structure in series bis(phosphine oxide) and β-ketophosphine oxide representatives for efficient coordination Tb3+ Eu3+ ions with formation complexes exhibiting high Tb3+- Eu3+-centered luminescence. analysis stoichiometry lanthanide obtained using XRD method reveals great impact bridging group nature between two phosphine moieties on mode ligands ions. imido-group facilitates deprotonation imido- followed by tris-complexes. spectral...
In this study, Nickel oxide-based catalysts (NixOx) were synthesized and used for the in-situ upgrading process of heavy crude oil (viscosity 2157 mPa·s, API gravity 14.1° at 25 °C) in aquathermolysis conditions viscosity reduction recovery. All characterizations obtained nanoparticles performed through Scanning Electron Microscopy (SEM), Transmission (TEM), Atomic Force (AFM), X-Ray Diffraction (XRD), ASAP 2400 analyzer from Micromeritics (USA), methods. Experiments catalytic non-catalytic...
The report introduces hybrid polyelectrolyte-stabilized colloids combining blue and green-emitting building blocks, which are citrate carbon dots (CDs) [TbL]+ chelate complexes with 1,3-diketonate derivatives of calix[4]arene. joint incorporation green blue-emitting blocks into the polysodium polystyrenesulfonate (PSS) aggregates is carried out through solvent-exchange synthetic technique. coordinative binding between Tb3+ centers CD surface groups in initial DMF solutions both facilitates...
Hydrophilic colloids (PSS-[Ln2(TCAi)2] and PSS-[LnCAi], where i = 1, 2, or 3 Ln Gd Tb) were prepared by precipitation of Gd(III) Tb(III) complexes with tetrathiacalix[4]arenes (TCAi) calix[4]arenes bearing two 1,3-diketone groups (CAi) from dimethylformamide to an aqueous solution poly(sodium 4-styrenesulfonate) (PSS). Dynamic light scattering transmission electron microscopy demonstrated the formation nanoparticles coated polymer. Luminescence decay measurements on Tb(III)-based allowed...
Abstract The work introduces hydrophilic PSS-[Tb 2 (TCAn) ] nanoparticles to be applied as highly sensitive intracellular temperature nanosensors. are synthesized by solvent-induced nanoprecipitation of [Tb complexes (TCAn - thiacalix[4]arenes bearing different upper-rim substituents: unsubstituted TCA1, tert-buthyl-substituted TCA2, di- and tetra-brominated TCA3 TCA4) with the use polystyrenesulfonate (PSS) stabilizer. responsive luminescence behavior within 293–333 K range in water is...
Chronic diseases, notably cancer, pose a significant global threat to human life. Oncologists and medical professionals addressing malignancies confront challenges such as toxicity multidrug resistance. To tackle these issues, the focus has shifted toward employment of multifunctional colloidal gold nanoparticles. This study aims design pH-sensitive doxorubicin-loaded nanoparticles using polyvinylpyrrolidone. The cytotoxic efficacy designed nanoarchitecture its doxorubicin counterpart was...
Abstract Linear N ‐substituted polyacrylamides bearing tricarboxylic moieties pendant to the backbone are synthesized, and coordinative binding approach is developed convert them into Gd 3+ /Eu ‐metallopolymers. Inner‐sphere coordination of lanthanide ions with chelating moieties, together their outer‐sphere stabilization by randomly coiled backbone, reasons for peculiar water proton relaxation luminescence properties metallopolymers obtained. Indeed, ‐metallopolymer, values longitudinal...
