Hydrazone-Containing Triblock Copolymeric Micelles for pH-Controlled Drug Delivery
In this study, the structure-activity relationship of amphiphilic block copolymer micelles as nanosized drug delivery system was revealed. Firstly, a biodegradable triblock polymers PEG-DiHyd-PLA containing hydrazone bond was synthesized through the ring-opening polymerization. In this method, PEG-DiHyd-Phenol was used as the initiator and L-lactide as the monomer. Then, the polymeric micelles ...

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...
متن کاملSynthesis of monodisperse organosilica nanoparticles with hollow interiors and porous shells using silica nanospheres as templates.
A versatile method for the formation of monodisperse, bridged silsesquioxane nanoparticles with hollow interiors and porous shells has been developed using silica nanospheres as templates. Tunable size and shell thickness, as well as high surface areas and large pore volumes of the hollow particles, allow for practical application of these nanoparticles in many fields.
متن کاملHydrogen peroxide-responsive micelles self-assembled from a peroxalate ester-containing triblock copolymer.
A novel ABA triblock copolymer by using peroxalate esters as linkages was synthesized. In water, this amphiphilic copolymer self-assembled into micelles which were used as drug delivery carriers. When stimulated with hydrogen peroxide, the micelles disassembled to release drugs since the responsive peroxalate ester linkages would be cleaved after the reaction with hydrogen peroxide.
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...
