A facile synthesis of highly water-soluble, core–shell organo-silica nanoparticles with controllable size via sol–gel process

Preparation, purification, and characterization of aminopropyl-functionalized silica sol

“…The reactivity of the silane towards the substrate is influenced by the hydrolysis rate of the alkoxy groups [4][5], and the catalytic activity of the functional side chain [6][7][8]. The presence of other catalysts like water, acid or base usually fastens the rate of the hydrolysis and/or the condensation [9][10][11][12][13]. Depending on the number of reactive alkoxy groups and the presence of catalysts the condensation between silane molecules (bulk phase polycondensation) occurs in parallel with surface modification [14][15].…”

Biocompatibility assessment of rice husk-derived biogenic silica nanoparticles for biomedical applications

“…4). The hLFCs were exposed to various concentrations (25,50,100,200 and 400 μg/mL) of bSNPs for 24 and 48 h. Ultimately, there was no difference between the control and the low concentration groups, whereas slight changes were observed at the high concentration group. Because the cell viability was greater than 85% at the high concentration groups, the results indicate that the bSNPs are biocompatible with hLFCs.…”

“…In particular, the high silica content in RH has attracted the attention of researchers for its potential use as a raw material for the production of silicon-based materials, including silicon carbide, silica, silicon nitride, silicon tetrachloride, pure silicon, and zeolite [19]. A variety of approaches are used for preparing silica nanoparticles from RH, such as microwave hydrothermal processes [23], flame synthesis [24], sol-gel processes [25], microemulsion methods [26], and combustion synthesis [27]. In the large-scale production of silica, quartz sand is treated with sodium carbonate at 1300°C [28].…”

Mesoporous Silica Nanoparticles: A Review

“…The versatile surface chemistry and small particle size of MSNs work as a sensor system for the detection of target within individual cell both in vivo and in vitro [122]. Nanoparticles have the ability to avoid fluorescence, self-quenching and other diffusion related issues.…”
