Upconverting nanoparticles (UCNPs) are of particular interest in nanomedicine for vivo deep-tissue optical cancer bioimaging due to their efficient cellular uptake dependent on polymer coating. In this study, particles, ca. 25 nm diameter, were prepared by a high-temperature coprecipitation lanthanide chlorides. To ensure optimal dispersion UCNPs aqueous milieu, they coated with three different polymers containing reactive groups, i.e., poly(ethylene glycol)-alendronate (PEG-Ale),...
High-quality upconverting NaYF4:Yb3+,Er3+ nanoparticles (UCNPs; 26 nm in diameter) based on lanthanides were synthesized by a high-temperature coprecipitation method. The particles modified bisphosphonate-terminated poly(ethylene glycol) (PEG) and Rose Bengal (RB) photosensitizer. thoroughly characterized using transmission electron microscopy, dynamic light scattering, thermogravimetric analysis, FTIR, X-ray photoelectron upconversion luminescence spectroscopy terms of morphology,...
Large (120 nm) hexagonal NaYF 4 :Yb, Er nanoparticles (UCNPs) were synthesized by high-temperature coprecipitation method and coated with poly(ethylene glycol)-alendronate (PEG-Ale), poly ( N , -dimethylacrylamide- co -2-aminoethylacrylamide)-alendronate (PDMA-Ale) or poly(methyl vinyl ether- -maleic acid) (PMVEMA). The colloidal stability of polymer-coated UCNPs in water, PBS DMEM medium was investigated dynamic light scattering; UCNP@PMVEMA particles showed the best PBS. Dissolution PBS,...
Different iron oxides (i.e., magnetite, maghemite, goethite, wüstite), particularly nanosized particles, show distinct effects on living organisms. Thus, it is of primary importance for their biomedical applications that the morphology and phase-structural state these materials are investigated. The aim this work was to obtain magnetic nanoparticles in a single reactor using Fe(III) acetylacetonate as initial precursor synthesis oleate or undecylate followed by thermolysis situ. We proposed...
In this report, we synthesized hexagonal NaYF4:Yb,Er upconverting nanoparticles (UCNPs) of 171 nm in size with a narrow particle distribution. To address their colloidal stabi-lity aqueous media and to incorporate photosensitizer that can produce reactive singlet oxygen (1O2) kill tumor cells, UCNPs were conjugated 6-bromohexanoic acid-functionalized Rose Bengal (RB) coated PEG-alendronate (PEG-Ale). The particles thoroughly characterized by transmission electron microscopy, dynamic light...
Different iron oxides (i.e., magnetite, maghemite, goethite, wüstite) show distinct effects on biological objects, and thus the investigations of morphology phase-structural state have prime priority for their biomedical applications. The aim this work was to develop one-pot synthesis magnetic nanoparticles by thermolysis Fe(III)-oleate or Fe(III)-undecylate in a high-boiling point solvent situ , using Fe(III)-acetylacetonate. Magnetic were characterized transmission electron microscopy,...
The content of total protein and its spectrum in the blood were studied when rats fed metal complexes (ME; Fe+2/+3-, Zn+2-, Cu+2 - Mn+2-) as part a polymer transporter (MEmLPEG400) diet deficient nutrients.
 It was found that complete diet, plasma is 107.5±3.0 g/l 15.6 17.8% higher experimental groups. At same time, animals groups, γ-globulins 2.3 2.9 times (р < 0.05 0.001) than while albumin, on contrary, reduced. β-globulins maximum (18.6±1.42%) control 6.8 11.6% (p lower wheat...
Розглянуто проблеми введення наночастинок магнетиту в гідрогелеві дисперсії, які створені на основі поліакриламіду.Утворення полімерного каркаса гідрогелю відбувалось за рахунок збалансованої кількості поперечних зшивок між поліакриламідом та полі-Nгідроксиметилакриламідом.Вивчено структурування поліакриламіду полі-N-(гідроксиметил)акриламіду присутності солей феруму -прекурсорів показано вплив добавок параметри тривимірної сітки гідрогелю.Проведено оптимізацію складу вивчення стабільності...
