Herein, dendrimer-modified montmorillonite (Mt)-decorated poly-Ɛ-caprolactone (PCL) and chitosan (CHIT)-based nanofibers were prepared. Mt was modified with a poly(amidoamine) generation 1 (PAMAMG1) dendrimer, the obtained PAMAMG1–Mt incorporated into PCL–CHIT nanofiber’s structure. The PCL–CHIT/PAMAMG1–Mt conjugated glutamate oxidase (GluOx) to design bio-based detection system for monosodium (MSG). added backbone provide multipoint binding side immobilize GluOx via covalent bonds. After...
Clay based biosensors were developed using montmorillonite (Mont) modified with methyl (M) and dimethylamine (DM). X-ray diffraction, Fourier transform infrared spectroscopy, zeta potential thermal gravimetric measurements used to characterize the clays. After immobilization of glucose oxidase (GOx) via clay on glassy carbon electrode, its application as a biosensor was investigated in detail. The best response characteristics obtained by DM-Mont optimization enzyme amount, reproducibility...
Diagnostic techniques based on biomolecules have application potential that can be realized in many fields, such as disease diagnosis, bioprocess imaging, food/beverage industries, and environmental pollutant imaging. Successful surface immobilization of is critical to increasing the stabilization, sensitivity, selectivity used bioassay systems. Nanofibers are good candidates for owing advantages morphology pore size. In this study, montmorillonite (MMT) clay modified with poly(amidoamine)...
Here we report the preparation, characterization and application of folic acid modified Montmorillonite clay (FA-Mont) as a cell culture material. Clays exhibit unique properties such good mechanical chemical stabilities, high surface area, low toxicity easy combination with functional organic groups. FA was used modifier to facilitate adhesion folate positive cells on surface. FA-Mont characterized using FT-IR, XRD, zeta potential measurements well thermogravimetric analyses. Finally, usage...
Trimethylamine (TM) intercalated montmorillonite (Mont) clay was prepared and characterized using X-ray diffraction, Fourier transform infrared spectroscopy, zeta potential thermal gravimetric measurements. Gluconobacter oxydans cells were immobilized on the micro-structured matrix used in microbial sensor applications. Sensor responses based respiratory activity of consumption oxygen monitored at −0.7 V (vs. Ag/AgCl platinum electrodes) by glucose as a substrate. Stabilization bacteria...
Here we report the synthesis, characterization and application of calixarene (Calix) modified montmorillonite (Mt) as a platform for bio-applications such biomolecule immobilization biosensing technologies.
The present work is the first that includes use of glycine (Gly), lysine (Lys) and glutamic acid (Glu) modified clay mineral matrices in biosensors.
In catalytic biosensors, the immobilization of biomolecules in a suitable matrix is one vital parameters for obtaining improved systems.
Abstract In this study, the influence of pH, electrolyte concentration, and type ionic species on electrokinetic properties (zeta potential charge density) acid-activated montmorillonite mineral have been investigated using microelectrophoresis method. The dispersions determined in aqueous solutions mono-, di-, trivalent salts divalent heavy metal salts. Zeta experiments performed to determine point zero (pzc) determining ions (pdi). zeta values particles were negative did not vary...
In the present study, vine stem and modified were used as low cost adsorbents for removal of acidic basic dyes from aqueous solutions. A comparative study was also carried out with activated carbon obtained then adsorption capacities all evaluated by batch process. The effects various parameters (initial pH, particle size, contact time) investigated. modification nitric acid increased its capacity dye. Both, exhibited higher than carbon. found to be 322.58, 250, 200 mg g−1 modified, natural...
Abstract Hydrophobic‐ and/or hydrophilic‐polymer‐grafted PDVB microspheres are synthesized by the combination of hydrobromination and click‐chemistry processes. The modified‐PDVB intermediates at various stages synthesis characterized using GPC, 1 H NMR FTIR spectroscopy TGA analysis. Use as a support matrix for reversible protein immobilization via adsorption is investigated. system parameters such conditions (i.e., enzyme concentration, medium pH) desorption studied evaluated with regards...
A series of poly(N-vinylimidazole)/montmorillonite nanocomposites were prepared by in situ polymerization. This method is the first example polymerization VI monomers within montmorillonite layers for preparation at different clay loading degrees. N-vinyl imidazole was intercalated into interlayer regions minerals ion exchange reaction. Then, this organomodified dispersed fluid degrees to conduct Polymerization through led exfoliated nanocomposite formation. X-ray diffraction (XRD) and...
