Xanthan gum-capped Chromia Nanoparticles (XG-CrNPs): A promising nanoprobe for the detection of heavy metal ions.

The present study reports on the selective and sensitive detection of metals using xanthan gum-capped chromia nanoparticles (XG-CrNPs). The nanoparticles were synthesized by the chemical reduction method using sodium borohydride and xanthan gum as the reducing and capping agents, respectively. The synthesis of XG-CrNPs was confirmed by the appearance of the two absorption peaks at 272 nm and 371 nm in the UV-visible region.

Efficient sensing of saccharin through interference synthesis of gum ghatti capped silver nanoparticles.

The presence of saccharin (SH) could be efficiently sensed (in the concentration range of 5 × 10 M to 5 × 10 M) through the interference synthesis of gum ghatti (GG) capped silver nanoparticles (GGAgNps). The synthesis used sodium borohydride and gum ghatti (GG) as the reducing and capping agents respectively. The strong hydrogen-bonding recognition between GG and SH was responsible for the interference.

Carboxymethyl cellulose-rosin gum hybrid nanoparticles: An efficient drug carrier.

Adequate release of 5-ASA in colon is challenging as it easily permeates at the acidic pH of the upper gastrointestinal tract. Targeting delayed release of 5-ASA at acidic pH, Carboxymethyl cellulose-rosin gum hybrid nanoparticles (CR) with an average size of 267nm have been crafted through nanoprecipitation method. CR was extensively characterized using Fourier Transform Spectroscopy (FTIR), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and particle size analysis based on dynamic light scattering.

Synthesis of Aloevera/Acrylonitrile based Nanoparticles for targeted drug delivery of 5-Aminosalicylic acid.

Aloevera (AV) polysaccharide/acrylonitrile (AN) nanoparticles (AVA of ∼50nm size) have been crafted via free radical polymerization method using persulfate/ascorbic acid (KPS/AA) and methylenebisacrylamide (MBA) as the redox initiator and crosslinker respectively. AVA was extensively characterized using FTIR, SEM, TEM, XRD, and Thermal analysis (TGA & DTG). Inclusion of AN in AV polysaccharide has been evidenced by nitrile stretching peak at 2244cm in FTIR spectrum of AVA Colon specific targeted in-vitro release of 5-Aminosalicylic acid from AVA has been studied in pH 1.

Grafting of vinyl acetate-ethylacrylate binary monomer mixture onto guar gum.

Present article reports on guar gum (GG) functionalization through graftcopolymerization of vinylacetate (VAC) and ethylacrylate (EA) from their binary mixtures. The potassium persulfate/ascorbic acid (KPS/AA) redox initiator system has been used for the binary grafting under the previously optimized conditions for VAC grafting at guar gum. The concentration of ascorbic acid (AA), persulfate (KPS), and grafting temperature were varied to optimize the binary grafting.
