Biodegradable hollow silica nanospheres containing gold nanoparticle arrays.
We introduce biodegradable hollow silica nanocapsules embedding arrays of 3 nm gold nanoparticles. The silica shell degrades in full serum in a few hours, potentially allowing the clearance of the capsules and their contents by the efficient renal pathway, and thereby overcoming accumulation issues typical of metal nanoparticles.
متن کاملSERS-based immunoassay of tumor marker VEGF using DNA aptamers and silica-encapsulated hollow gold nanospheres.
A novel SERS-based sandwich immunoassay using DNA aptamers, silica-encapsulated hollow gold nanospheres (SEHGNs) and a gold-patterned microarray was developed for sensitive detection of VEGF (vascular endothelial growth factor) angiogenesis protein markers. Here, a DNA aptamer conjugated to SEHGN was used as a highly reproducible SERS-encoding nanoprobe, and a hybrid microarray including hydrop...
متن کاملNanoparticle-Assisted STED Nanoscopy with Gold Nanospheres
We demonstrate stimulated emission depletion (STED) microscopy with 20 nm gold nanospheres coated by fluorescently doped silica. We demonstrate significantly improved spatial resolution down to 75 nm, which is the first time that hybrid NPs are used in STED imaging beyond the diffraction limit of confocal microscopy. Unlike previous demonstrations of super-resolution with metal nanoparticles wi...
متن کاملFormation of hollow silica nanospheres by reverse microemulsion.
Uniform hollow silica nanospheres (HSNs) synthesized with reverse microemulsion have great application potential as nanoreactors because enzymes or nanocatalysts can be easily encapsulated de novo in synthesis. Water-in-oil (w/o) reverse microemulsions comprising the polymeric surfactant polyoxyethylene (5) isooctylphenyl ether (Igepal CA-520), ammonia and water in a continuous oil phase (alkan...
متن کاملSynthesis of Hollow Silica Nanospheres with Microemulsion as Template
Materials: Cyclohexane, n-hexanol (98%), ammonia hydroxide (28~30 wt%), tetraethylorthosilicate (TEOS, 98%), (3-aminopropyl)trimethoxysilane (APTS, 95%), polyoxyethylene(10)isooctylphenylether (TritonX-100), fluorescein isothiocyanate isomer I (FITC, 90%), Iron(III) acetyl acetonate (Fe(acac)3, 99+%), and benzyl ether (99%) were purchased from Acrös. 1,2 dodecanediol (90%), oleylamine, and olei...
