Abstract Increased extracellular Ca 2+ concentrations ([Ca ] ex ) trigger activation of the NLRP3 inflammasome in monocytes through calcium-sensing receptor (CaSR). To prevent extraosseous calcification vivo, serum protein fetuin-A stabilizes calcium and phosphate into 70-100 nm-sized colloidal calciprotein particles (CPPs). Here we show that engulf CPPs via macropinocytosis, this process is strictly dependent on CaSR signaling triggered by increases [Ca . Enhanced macropinocytosis results...
Poly(N-isopropylacrylamide) (PNiPAm) and poly(2-ethyl-2-oxazoline) (PEtOx) represent two polymer types that are well-known for their lower critical solution temperature (LCST) behavior in aqueous media. To synthesize triblock copolymers containing both polymers, a crossover of different polymerization methods was applied using bifunctional initiator the living cationic ring-opening (CROP) EtOx. Quantitative end-functionalization with trithiocarbonate resulted PEtOx macro chain transfer agent...
Amphiphilic gradient copolymers with thermoresponsive properties were synthesized in one pot <italic>via</italic> RAFT copolymerization.
In order to obtain a novel, pH responsive polymersome system, series of block copolymers were synthesized via the reversible addition-fragmentation chain transfer (RAFT) polymerization 3,4-dihydro-2H-pyran (DHP) protected 2-hydroxyethyl methacrylate (HEMA) (2-((tetrahydro-2H-pyran-2-yl)oxy)ethyl (THP-HEMA)) and 2-(dimethylamino) ethyl (DMAEMA) using p(THP-HEMA) as macro agent (mCTA). The degree (DP) was fixed 35, whereas DP p(DMAEMA) systematically varied from 21 50. aqueous solution,...
A block copolymer library of polylactide and poly(2-hydroxyethyl acrylate) was prepared <italic>via</italic> sequential ring opening polymerization RAFT in a one-pot approach.
Boron nitride nanotubes (BNNTs), the structural analogues to carbon (CNTs), attracted considerable attention due their excellent properties. However, synthesis of BNNTs suffers from high-temperature requirement, which increases cost and adds complexity instruments (arc-discharge, plasma-assisted CVD, etc.), preventing further exploration use harmful chemicals (catalytic chemical vapor deposition) resulting in unwanted byproducts. Here, we demonstrate sulfur-containing compound-assisted at a...
Nanoparticles with light-to-heat conversion properties play vital roles in the design of photothermal materials that can be remotely heated via light activation. Halloysite nanotubes (HNTs), versatile natural clay nanoparticles, were converted into efficient agents by functionalizing them polydopamine, a polymer properties. By varying polydopamine functionalization reaction conditions such as dopamine concentration, time, and nature HNTs, HNT-polydopamine (HNT-PDA) nanohybrids comprising...
Polymer based nanoparticles offer great opportunities for diverse applications, i.e. their drug delivery potential is promising. However, major drawback identified in preparation via the nanoemulsion technique, which needed encapsulation of hydrophilic drugs and whereby utilization surfactants, e.g. poly(vinyl alcohol) (PVA), mandatory. Furthermore, critical due to need lyophilization storage. For this reason it common use cryoprotectants, are usually sugar based. In current study, we...
Abstract This paper presents the synthesis and characterization of d ‐fructose modified poly(ethylene glycol) (Fru‐PEG) fructose glycol)‐ block ‐poly(ethyl hexyl glycidyl ether) (Fru‐PEG‐ b ‐PEHG) that are both prepared by initiation with isopropyliden protected fructose, followed deprotection sugar. The copolymers self‐assembled into micelles, subsequently characterized cryo‐TEM dynamic light scattering. fluorescent dye Nile red is encapsulated as a model hydrophobic compound marker to...
Recently, a simple strategy was developed for preparing interconnected interpenetrating polymer networks (IPNs) based on butyl rubber (IIR) and poly(n-octadecyl acrylate) (PC18A). Solvent-free UV polymerization of n-octadecyl acrylate (C18A) monomer in the melt IIR at ambient temperature resulted IPNs with self-healing shape-memory functions. Here, we demonstrate that use grafted acrylic acid, methacrylic 10-undecenoic acid instead unmodified provides significant improvement mechanical...
Abstract Calcium and phosphate are well known as the main minerals in bone ossification. But they also have an immunomodulatory potential components of calciprotein particles. Such particles precipitate spontaneously body fluids if calcium homeostasis is disturbed. An abnormally increased mineral load could lead to soft tissue calcification. In our study we investigated cellular response freshly isolated peripheral blood monocytes serum-containing medium under precipitating (high high...
