Incorporation of Luminescent Nanocrystals into Monodisperse Core–Shell Silica Microspheres

Learning from Biosilica: Nanostructured Silicas and Their Coatings on Substrates by Programmable Approaches

“…The dye entrapped into silica nanospheres did not show bleach even dispersed in methanol for over one year. Thus these novel TSPP-functionalized silica nanoparticles would be superior to some of conventional dye-encapsulated silica nanoparticles based on Stöber routes by either using silica source with chemically-bonded-dyes or physically doping dyes into silica network, in which dye incorporation is not easily controllable (Chan et al, 2004).…”

Incorporation of Iron Oxide Nanoparticles and Quantum Dots into Silica Microspheres

“…15 This fabrication method is advantageous because it maintains the monodisperse MS size and QD optical properties, and the nanoparticles are incorporated uniformly into the MS shell. We have modified the shell of the microspheres to include not only QDs, but MPs as well.…”

“…15 In a typical procedure, as-synthesized QDs were precipitated twice with a 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 …”

“…The procedure for incorporating MPs and QDs together into silica microspheres was adapted from Chan et al 15 In a typical procedure, 30 mg bare silica microspheres and 16 mg of hydroxypropyl cellulose (HPC) were added to 10 mL of ethanol, and this mixture was sonicated for ten minutes. 50-500 µL of MP solution and 10 µL of QD solution were added into the reaction mixture while vigorously stirring, followed by the addition of 50 µL of H 2 O, 50 µL of NH 4 OH, and 0.15 mL TEOS.…”

Preparation and properties of antibacterial TiO2@C/Ag core–shell composite

“…Nanomaterials with core-shell structure have been extensively studied because of their multifunctional properties and various applications, such as drug delivery [8] and increasing their solubility and stability [9,10] and altering the emission properties of quantum dots [11,12]. In addition to the above-mentioned characteristics, core-shell nano-oxides such as TiO 2 @X and ZnO@X also have unique antibacterial properties that have attracted attention to this area in recent years [13][14][15][16].…”
