Here, we propose a recyclable approach using acrylonitrile-butadiene-styrene (ABS) residues from additive manufacturing in combination with low-cost and accessible graphite flakes as novel potential mixture for creating conductive paste. The particles were successfully incorporated the recycled thermoplastic composite when solubilized acetone demonstrated greater adherence to different substrates, among which cellulose-based material made possible construction of paper-based electrochemical...
The integration of multiple functionalities into single theranostic platforms offers new opportunities for personalized and minimally invasive clinical interventions, positioning these materials as highly promising tools in modern medicine. Thereby, magneto-luminescent Janus-like nanoparticles (JNPs) were developed herein, encapsulated near-infrared (NIR) light- pH- responsive micelle-like aggregates (Mic) simultaneous magnetic targeting, biomedical imaging, photothermal therapy, NIR-light...
We report on the development of a simple and easy to use microchip dedicated allergy diagnosis. This combines both advantages homogeneous immunoassays i.e. species diffusion heterogeneous separation preconcentration steps. In vitro diagnosis is based specific Immunoglobulin E (IgE) quantitation, in that way we have developed integrated magnetic core-shell nanoparticles (MCSNPs) as an IgE capture nanoplatform microdevice taking benefit from their colloidal properties. Integrating such...
In the last decades, fluorescent quantum dots (QDs) have appeared as high-performance biological nanoprobes and been explored for a variety of biomedical optical imaging applications. However, many central challenges still exist concerning control surface chemistry to ensure high biocompatibility, low toxicity, antifouling, specific active targeting properties. Regarding in vivo applications, circulation time clearance nanoprobe are also key parameters design characterization new agents....
The hyphenation of CE with MS is nowadays accepted as a powerful analytical approach. Employing ESI, the most common interface, one challenge to provide quantitative information, which quite difficult task, it linked, among other factors, suction and dilution effects. In coaxial ESI configuration, effect has been presented in literature stemming from nebulizing gas (NG) flow rate drying temperature. But this interface consists three concentric capillaries, allowing for BGE, sheath liquid...
Abstract In view of employing functionalized nanoparticles (NPs) in the context an immunodiagnostic, aminated maghemite/silica core/shell particles were synthesized so as to be further coated with antibody or antigen via amino groups at their surface. Different functionalization rates obtained by coating these 3‐(aminopropyl)triethoxysilane and 2‐[methoxy(polyethyleneoxy)propyl]‐trimethoxysilane different molar ratios. Adequate analytical performances CE coupled UV‐visible detection through...
The study of the structural bases biological properties algal fucoidan (Ascophyllum nodosum) led us to look for enzymes able modify this sulfated polysaccharide. In context, we found a sulfoesterase activity in digestive glands common marine mollusk Pecten maximus, which is active on fucoidan. This was shown by capillary electrophoresis and 13C-1H NMR (500 MHz) analysis enzymatic hydrolysis fucoidan, oligosaccharides fucose isomers. We report exhaustive list all proton carbon chemical shifts...
The interaction of proteins with polysaccharides represents a major and challenging topic in glycobiology, since such complexes mediate fundamental biological mechanisms. A new strategy based on the hyphenation frontal analysis capillary electrophoresis (FACE) electrospray ionization mass spectrometry (ESIMS) is reported for characterization protein/carbohydrate complexes. While most previously CE−MS experiments were performed using zone format, we report first time which CE was (FACE−MS)....
The hyphenation of CE with MS is nowadays accepted as a powerful analytical approach. As far ESI, the most common interface, concerned, one challenge to provide sensitive well quantitative information, which quite difficult task, it linked, among other factors, suction and dilution effects. In coaxial ESI configuration, has been previously demonstrated that effect depends on many parameters inherent interface geometry, prevailing ones being capillary protrusion from needle, sheath liquid...
Abstract Size‐sorted maghemite (γ‐Fe 2 O 3 ) particle populations of number mean solid diameters ranging from 6 to 10 nm were suspended and directly characterized in their stabilizing acidic, citrated or basic aqueous media using CZE coupled with UV detection. Analytical conditions optimized order ensure reliable mobility measurements these ferrofluids anionic cationic forms. Particular interest has been paid the investigation positively charged since colloids have received little attention...
