Abstract The amylose‐ibuprofen (IBU) inclusion complexes were prepared through the enzymatic polymerization of amylose in presence IBU and by acidification an alkali solution (KOH/HCl). XRD analysis indicated that formed V‐type crystalline. Raman further confirmed formation amylose‐IBU complexes. clusters Am‐IBU complex observed as spherical particles sizes ranging from 30 to 80 nm AFM images. stable simulated gastric fluid, but was sustainedly released medium small intestine. This is...
Dextran hydrogel was prepared by the crosslinking reaction of dextran and N,N-methylenebisacrylamide in aqueous sodium hydroxide solution. Highly stable uniformly distributed silver nanoparticles have been using these networks as a carrier via situ reduction nitrate without addition any reducing agent. The spherical with diameters 20–30 nm were found to adopt face centered cubic structure. hybrid can be effectively employed antibacterial catalytic materials.
To elucidate the α-glucosidase (α-GC) inhibitory mechanism of theaflavin-3-gallate (TF-3-G), their interaction was investigated using spectroscopy and molecular docking analysis. The inhibition ratio TF-3-G against α-GC determined to be 92.3%. Steady fluorescence showed that effectively quenched intrinsic through static quenching, forming a stable complex hydrophobic interactions. Formation TF-3-G/α-GC also confirmed by resonance light scattering spectroscopy. Synchronous circular dichroism...
Rapid and selective removal of micropollutants from water is important for the reuse resources. Despite hollow frameworks with specific functionalized porous walls adsorption based on a series interactions, tailoring stable shape nanometer- micrometer-sized architectures pollutants remains challenge. Here, exactly controlled sheets, tubes, spherical were presented crosslinking supramolecular colloids in polar solvents. The strongly depended architecture original colloids. As entropy...
Abstract Differential scanning calorimetry (DSC), FTIR, X‐ray diffraction (XRD), and viscosity methods were used to examine the miscibility, interaction, degradability of cationic guar gum (GG) sodium carboxymethylcellulose (NaCMC) in their blend films. The experiment results prove that there exist electrostatic interactions hydrogen bonding between GG NaCMC. Blend films degrade quicker than pure or NaCMC film. Furthermore, degradation rate is related Based on research as drug carriers for...
Surface-enhanced Raman spectroscopy (SERS) can significantly enhance scattering signals of samples located at or very close to the Ag nanoparticles. The flexible SERS substrates may broaden application technology because high efficiency, conveniently collecting in situ detecting liquid samples. glutaraldehyde cross-linked branched polyethylenimine loading silver nanoparticles (bPEI/AgNPs) composite with dual three-dimensional (3D) network structures was synthesized under vortex room...
Tea polysaccharides exhibit multiple important bioactivities, but very few of them can be absorbed through the small intestine. To enhance absorption efficacy tea polysaccharides, a cationic vitamin B12-conjugated glycogen derivative bearing diethylenetriamine residues (VB12-DETA-Gly) was synthesized and characterized using FTIR, 1H NMR, UV-vis spectroscopy. An acidic polysaccharide (TPSA) isolated from green tea. The TPSA/VB12-DETA-Gly complexed nanoparticles were prepared, which showed...
A series of water‐soluble cellulose derivatives with thermo‐ and pH‐sensitive properties were prepared in aqueous solutions by the graft copolymerization N‐isopropylacrylamide (NIPAAm) on carboxymethylcellulose (CMC). Ceric ammonium nitrate (CAN) was used combination nitric acid as initiator system. The effects various factors such CAN concentration, NIPAAm CMC amounts well reaction temperature grafting percentage efficiency studied. resultant characterized respect to their structure...

Poly(methylthiomethyl methacrylate) (PMTMA) is miscible with poly(p-vinylphenol) (PVPh) as shown by the existence of a single glass transition temperature in each blend. Fourier transform infrared spectroscopy, solid-state 13C nuclear magnetic resonance and X-ray photoelectron spectroscopy show that miscibility arises mainly from interactions between hydroxyl groups PVPh thioether sulfur atoms PMTMA. Measurements proton spin−lattice relaxation time rotating frame, T1ρ(H), reveal blends has...
