C-Phycocyanin (PC) and B-phycoerythrin (PE) are light-harvesting water-soluble phycobiliproteins from microalgae that belong mainly to the cyanobaceria rhodhophytes families. Different methods have been developed for PC PE extraction purification microalgae, offer a high potential their use as additives in sectors such food cosmetics. However, main limitations of using these dyes sensitivity en...

Heavy metal toxicity in water is a serious problem that may have harmful effects on human health and the ecosystem. Lead [Pb(II)] cadmium [Cd(II)] are two such heavy ions, present water, whose severity well-known well-studied. In current research, magnetic biochar composite (MBC) studied as an adsorbent material for effective removal of lead ions from solutions. Magnetite (Fe3O4) nanoparticles ...

Abstract Objective Incorporating silane-coupling agent into universal adhesives (UAs) to simplify adhesive luting of glass-ceramic restorations appeared ineffective due silane’s instability in an acidic aqueous solution. This study aimed evaluate new silane technology added experimental UA be bonded glass ceramics without separate prior silanization. Methods Combined technology, consisting 3-(a...

Starvation of the polyamine-dependent Chinese-hamster ovary cells for ornithine or ornithine-derived polyamines in serum-free culture resulted in the formation of cadaverine and its aminopropyl derivatives, N-(3-aminopropyl)cadaverine and NN'-bis(3-aminopropyl)cadaverine. The synthesis of these unusual amines was inhibited by treatment of the cells with DL-2-difluoromethylornithine, a specific ...

Introduction: Further development of magnetic-based detection techniques could be significant use in increasing the sensitivity and quantification hepatitis B virus (HBV) infection. The present work addresses fabrication characterization a new bio-nano composite based on immobilization goat anti-HBsAg antibody modified core-shell magnetic nanoparticles (NPs) by (3-aminopropyl) triethoxysilane (...

A new chelating matrix has been prepared by immobilizing 1,8-dihydroxyanthraquinone (DHAQ) on silica gel modified with (3-aminopropyl)triethoxysilane. After characterizing the matrix with thermogravimetric analysis (TGA), cross polarization magic angle spinning (CPMAS) NMR and diffuse reflectance infrared fourier transformation (DRIFT) spectroscopy, it has been used to preconcentrate Pb(II), Cd...

Mesoporous TiO2-SiO2 nanocomposite (TS) was synthesized via sol-gel method and Amino-functionalized using 3-(aminopropyl) triethoxysilane. prepared amino-functionalized TiO2-SiO2 (NH2TS) was evaluated for eliminating radioactive Th(IV) ion in comparison with (TS). The prepared nanocomposites were characterized using FT-IR,  XRD, DSC-TGA...

Objective(s): Study and development of antifouling nanosystem for conjugation of drugs were attracting great attention in recent years. The present study aimed to develop novel curcumin-loaded silica nanoparticles containing zwitterionic coating as an antifouling system to provide protein corona free nanoformulations for curcumin. Materials and Methods: Silica nanoparticles were prepared ...
