CONTEXT Thiomers could prove to be suitable mucoadhesives for fabrication of ocular inserts. OBJECTIVE The study intends to explore the application of thiolated sodium alginate (TSA) to the preparation of bilayered ocular inserts of gatifloxacin. METHODS Cysteine moieties were grafted onto sodium alginate (SA) and the resultant thiomer was characterized for relevant physicochemical properti...
The main aim of this work was to develop novel targeted sterically stabilised pH-sensitive liposomes tailored to promote efficient intracellular delivery of therapeutic molecules into human T-leukaemia cells. Our results indicate that the targeting moiety (thiolated transferrin) was successfully coupled to the distal reactive maleimide terminus of poly(ethylene glycol)-phospholipid conjugates i...
The aim of this study was to prepare and evaluate mucoadhesive core-shell nanoparticles based on copolymerization of thiolated chitosan coated on poly methyl methacrylate cores as a carrier for oral delivery of docetaxel. Docetaxel-loaded nanoparticles with various concentrations were prepared via a radical emulsion polymerization method using cerium ammonium nitrate as an initiator. The physic...
The interactions between nonpolar surfaces coated with the nonionic surfactant hexaoxyethylene dodecyl ether C12E6 were investigated using two techniques and three different types of surfaces. As nonpolar surfaces, the air/water interface, silanated negatively charged glass, and thiolated uncharged gold surfaces were chosen. The interactions between the air/water interfaces were measured with a...
A novel design of gold-coated iron oxide nanoparticles was fabricated as a potential delivery system to improve the efficiency and stability of d, l-sulforaphane as an anticancer drug. To this purpose, the surface of gold-coated iron oxide nanoparticles was modified for sulforaphane delivery via furnishing its surface with thiolated polyethylene glycol-folic acid and thiolated polyethylene glyc...
N-[2-(acryloyloxy)ethyl]-N,N-dimethyl-N-butylammonium iodide was successfully photo-polymerized from native and thiolated PDMS surface, in the presence of benzophenone. The directly indirectly grafted surfaces exhibited quaternary ammonium densities about 1015 1017 N+.cm?2, respectively, very high hydrophilicity compared to non-grafted surfaces. live dead tests performed by fluorescence microsc...
Recycling precious metals from the increasing amount of e-waste is significant for sustainability strategic metal resources. However, few technologies have been reported efficient and highly selective recovery strong acidic leachate. Herein, we demonstrated a simply synthesized thiolated ?-cyclodextrin (T-CD) that can recover gold multi-metal coexistence solutions at pH 2 with an exceptional ad...
An experimental approach for improving the sensitivity of the surface plasmon resonance (SPR) DNA hybridization sensor using gold nanoparticles (GNPs), modified by specific oligonucleotides, was elaborated. An influence of the ionic strength on the aggregation stability of unmodified GNPs and GNPs modified by the thiolated oligonucleotides was investigated by monitoring a value of light extinct...
We show that cantilever array sensors can sense the formation of supported phospholipid bilayers on their surface and that they can monitor changes in mechanical properties of lipid bilayers. Supported lipid bilayers were formed on top of microfabricated cantilevers by vesicle fusion. The formation of bilayers led to a bending of the cantilevers of 70-590 nm comparable to a surface stress of 27...
Posttranslational modifications (PTMs) of cytoskeleton proteins due to oxidative stress associated with several pathological conditions often lead to alterations in cell function. The current study evaluates the effect of nitric oxide (DETA-NO)-induced oxidative stress-related S-glutathionylation of cytoskeleton proteins in human PMNs. By using in vitro and genetic approaches, we showed that S-...
