Insects, renowned for their abundant and renewable biomass, stand at the forefront of biomimicry-inspired research offer promising alternatives chitin chitosan production considering mounting environmental concerns inherent limitations conventional sources. This comprehensive review provides a meticulous exploration current state insect-derived chitosan, focusing on sources, methods, characterization, physical chemical properties, emerging biomedical applications. Abundant insect sources...
This series of two papers is devoted to the effect organic dye (methylene blue, MB; or methyl orange, MO) adsorption on surface either bare citrate-coated magnetic iron oxide nanoparticles (IONPs) their primary agglomeration (in absence an applied field) and secondary field-induced agglomeration. The present paper (Part I) focused physicochemical mechanisms adsorption-induced IONPs. Dye oppositely charged IONPs found be mostly promoted by electrostatic interactions very sensitive pH ionic...
Conjugation of a lipid moiety via "click chemistry" potentiates the cellular uptake oligonucleotides and allows their intracellular delivery. These nontoxic conjugates efficiently inhibit hepatitis C virus internal ribosome entry site (IRES)-mediated translation in human hepatic Huh7 cells. The biological activity lipid-conjugated is not affected by presence serum.
In this work, novel 3,4-phenylenedioxythiophene (PhEDOT) monomers with alkyl, branched, and aromatic substituents were synthesized tested for their efficacy at forming surfaces unique wetting properties surface morphology without the aid of surfactants.
A family of new glycosyl-nucleoside lipids (GNLs) that were prepared using a convenient "double click" chemistry route is described. Physicochemical studies (surface tension measurements, gelation properties, and transmission electron microscopy) indicate these amphiphiles spontaneously assemble into supramolecular structures including fibers, vesicles, hydrogels, organogels. GNLs possess unique properties both in water chloroform. very low minimum concentration 0.1% (w/w) was observed the...
A glycosyl–nucleoside–lipid self-assembles to give highly organized structures such as fibers and nanotubes, which can stabilize hydrogels; carbohydrate moieties provide a suitable environment deliver nucleic acids into human cells.
A polystyrenylphosphonium polymer was synthesized and complexed with various carboxylic acid derivatives to form new solid-state polyelectrolyte-surfactant assemblies. The properties of these ionic materials were highly dependent on the nature anion included a brittle material, rubbery ball that bounces, or sticky fiber. values for equilibrium modulus, storage loss modulus composition number electrostatic interactions. Small-angle X-ray scattering studies supramolecular assemblies confirmed...
Here we describe an automated synthetic pathway for the synthesis of fluorocarbon oligonucleotide conjugates (FONs) featuring hydrophobic and lipophobic moieties. The presence highly fluorinated chains allows delivery nucleic acids into human cells.
We report for the first time use of click chemistry both to modify surface morphology and obtain superhydrophobic properties. Using as a postfunctionalization poly(3,4-ethylenedioxythiophene) nanofibers bearing azido groups, we show that nanostructures already present on well hydrophobicity are highly affected by used alkyne. These results allow one envisage widely varied strategies nanostructured surfaces while introducing various functions, example produce biosensors or antibacterial surfaces.
The control in surface hydrophobicity and water adhesion is extremely important for various applications harvesting, oil/water separation membrane, energy systems or biosensing, example. Here, the first time we show that use of fluorescent monomers such as pyrene with substituents differing by their hydrophobicity, size, rigidity/flexibility can lead to surfaces tunable fluorescence properties a direct electropolymerization process. Seven original fluoroalkyl, alkyl, phenyl, adamantyl,...
Nucleic acid-based fluorinated derivatives, e.g., nucleosides or oligonucleotides connected to highly chains labeled with one more fluorine atoms, have been investigated recently due their high potential for biomedical applications. This review deals recent works on nucleoside and oligonucleotide fluorocarbon amphiphiles as well properties applications of fluorine-labeled analogues.
