The present paper shows the results of nanocomposite polymer electrolytes (SPEs) montmorillonite (MMT; Na+SYN-1) and gellan gum obtained by solution casting method. membrane samples were characterized ATR-FTIR, time-domain nuclear magnetic resonance (TD-NMR), scanning electron microscopy (SEM). Then, two chosen applied in small electrochromic devices (ECDs). ATR-FTIR revealed shifts bands aceta...

Fiber bundles are present in many tissues throughout the body. In most cases, collagen subunits spontaneously self-assemble into a fibrilar structure that provides ductility to bone and constitutes the basis of muscle contraction. Translating these natural architectural features into a biomimetic scaffold still remains a great challenge. Here, a simple strategy is proposed to engineer biomimeti...

A simplified enrichment method in which centrifugation is used for selective isolation of Sporichthya strains from soil is described. Gellan gum plus 2 mM CaCl2 stimulated growth of Sporichthya polymorpha KCC A0089 so that this organism was readily recognized on an isolation plate. High yields of motile spores were obtained by using a flooding solution containing 0.1% skim milk in 10 mM MOPS (m...

Gellan gum (GG) has been used to prepare polymeric carriers with prolonged retention on the eye surface for topical ocular drug delivery. In this work, GG was chemically modified short poly(2-ethyl-2-oxazoline) (PEtOx) chains that were expected have minimal adhesion mucosal tissues (mucoadhesion). The choice of synthetic procedure, solvents, and reagents dictated by biocompatibility materials p...

Fluconazole was studied with two different hydrophilic cyclodextrins (hydroxypropyl-β-cyclodextrin (HPBCD) and sulfobutyl ether-β-cyclodextrin (SBECD)) for the formation of inclusion complexes. HPBCD and SBECD showed low cell cytotoxicity in human keratocytes as assessed by the label-free xCELLigence system for real-time monitoring. The fluconazole-HPBCD complex was incorporated into an ion-sen...

Innovative hydrogels obtained by physical and chemical crosslinking of deacylated Gellan gum have been characterized in terms of water uptake, rheological properties and compressibility, and the behaviour of the tested materials, according to the type of the obtained network, is thoroughly discussed. The release from the various gels of loaded model molecules of different steric hindrance was a...

Complex formation between a natural polysaccharide – gellan and an antimicrobial drug ofloxacin was studied in aqueous solution. Conductimetric potentiometric titration curves revealed that forms water-soluble complex of composition 2:1 mol/mol stabilized by ionic hydrogen bonds. The the gellan-ofloxacin confirmed FTIR spectroscopy, dynamic light scattering, zeta-potential thermogravimetric ana...
