background: the excellent biocompatibility, biodegradability and biological properties of the hydrogels, fabricated using natural polymers, especially polysaccharides, are very advantageous for biomedical applications. gum tragacanth (gt) is a heterogeneous highly branched anionic polysaccharide, which has been used extensively in food and pharmaceutical industries. despite,  its desirable prop...

Herein we present silver nanoparticles (AgNPs)-doped inorganic–organic hybrid silica films on glass and polypropylene substrates. A sol in alcoholic medium was prepared at room temperature using TEOS, GLYMO, APTES. Silver were generated situ within the sol. AgNPs-SiO2 film obtained by dip coating method following drying 80 °C. FTIR spectra shows several vibrational bands of network amine functi...

In order to achieve prolong corneal contact time of norfloxacin(NFX) for treatment of extra ocular diseases, a pH triggered nanoparticulate in situ gelling system was designed to explore dual advantage of nanoparticles and in situ gelling system, for its ocular delivery. NFX loaded nanocarriers were developed by ionotropic gelation technique using chitosan as a matrix forming polymer, cross-lin...

Spatial properties of field soils vary in a complex manner. Especially in arid and semiarid areas, this variability affects plant quality and crop production. An experimental field plot was extensively sampled regarding soil water (378 gravimetrical samples), soil chemical content (314 samples), and crop yield and chemical content (26 samples) at the Cherfech agricultural field research station...

Implication for health policy/practice/research/medical education: Development of polymeric in situ gels for controlled release of various drugs provides a number of advantages over conventional dosage forms. Some important advantages of these smart systems are ease of application and reduced frequency of administration, as well as protection of the drug from environmental conditions. Published...

A comparing study on formation and microstructure features of aluminum titanate is investigated through both solid-state and sol-gel processes. Aluminum titanate formed by firing at 1350ºC and 1450ºC for 4h in solid-state process. In the sol-gel process formation of submicron sized particles is followed by addition of sucrose into the transparent sol. XRD analysis was confirmed the formation of...

We successfully synthesized two different structures, silica nanospheres and porous polymer membranes, via nanophase separation, based on a sol-gel process. Silica sol, which was in situ polymerized from tetraorthosilicate, was used as a precursor. Subsequently, it was mixed with a polymer that was used as a matrix component. It was observed that nanophase separation occurred after the mixing o...

In-situ forming polymeric gelling systems has become prominent among novel drug delivery system (NDDS) in recent years due to advantages such as sustained and prolonged drug action, improved patient compliance and reduced frequency of administration of the drug in comparison to conventional drug delivery system (DDS). This is a type of mucoadhesive DDS where the polymeric formulation is in sol ...
