    Antioxidant and Antiradical SiO2 Nanoparticles Covalently

    Gallic acid (GA) and its derivatives are natural polyphenolic substances widely used as antioxidants in nutrients, medicine and polymers. Here, nanoantioxidant materials are engineered by covalently grafting GA on SiO2 nanoparticles (NPs). A proof-of-concept is provided herein, using four types of well-characterized SiO2 NPs of specific surface area (SSA) 96–352 m2/g. All such hybrid SiO2-GA

    Nanotechnology: Review of concepts and potential application

    By introducing nanoparticles into the sensing matrix, the surface area on which color precursor molecules are located can be increased significantly. The detection of invA gene of Salmonella by combining DNAzyme probe self-assembled gold nanoparticles and polymerase chain reaction (PCR) was demonstrated by Luo et al. (2014). A capture probe

    Influence of Silica Nanoparticles on Antioxidant Potential

    It was found that if introduced into a nutrient medium of 0.05–1 g/L nano-SiO2, the oxidant activity (OA) of the culture medium (CM) of bacilli increased by 43.2–60.1 % and the antioxidant activity (AA) decreased by 4.5–11.8 %. SiO2 nanoparticles had different effects on antiradical activity (ARA) of the CM of Bacillus subtilis IMV B-7023. In particular, nano-SiO2 had no

    Therefore, the goals of this work were (1) to develop and characterize an antioxidant nanomaterial based on the caffeic acid covalently linked onto a core–shell silica nanosphere, (2) to evaluate its in vitro antioxidant capacity as an antiradical (2,2-diphenyl-1-picryl-hydrazyl (DPPH )), metal-chelating (Fe 2+) agent, and a singlet oxygen
