Nanoreactors for particle synthesis

3D Optical Heterostructure Patterning by Spatially Allocating Nanoblocks on a Printed Matrix

“…In nature, living organisms can synthesize various hierarchical structures through bottom-up self-assembly, which inspires people to construct functional materials via solution-based colloidal assembly. ,− The past decades have witnessed great advancements in assembly from colloidal nanoblocks and assembly mechanisms to properties and applications, , which also promotes the development of optical heterostructures via the assembly methods − including DNA direction, − grafted molecule integration, , and sequential dewetting. − In particular, the combination of nanoscale physical templates with evaporation-induced self-assembly boosts the accurate location and spatial arrangement of highly ordered heterogeneous superlattices. , But the high-resolution templates prepared by lithography are limited by complicated processing and high cost, unavoidably hindering the rapid and facile assembly of heterostructures. Recently, a coassembly strategy by soft liquid confinement has also been developed for the programmable patterning of binary heterostructures, , which provides the feasibility to precisely regulate the heterostructure morphology by manipulating the liquid property.…”

Polymer-Mediated Particle Coarsening within Hollow Silica Shell Nanoreactors

“…10−13 Nanoreactor-based strategies have emerged as a promising means to tune particle size, 14−17 composition, 18,19 and structure, 20,21 in ways that exceed what is possible with traditional syntheses that depend on tailoring reduction kinetics and ligand chemistry. 22,23 Nanoreactors operate by confining reactants within nanoscale volumes in order to deterministically drive complete conversion of reactants to particle products. 24 For example, scanning probe block copolymer lithography (SPBCL)generated polymeric domes on surfaces have been extensively used as reactors for the synthesis of a wide variety of particle types 20,21,25−27 and then screened for properties of interest.…”

Amphiphilic Diblock Copolymers Bearing Poly(Ethylene Glycol) Block: Hydrodynamic Properties in Organic Solvents and Water Micellar Dispersions, Effect of Hydrophobic Block Chemistry on Dispersion Stability and Cytotoxicity

“…Due to the beneficial combination of practically important properties (small size, high dispersion stability, and ability to solubilize hydrophobic compounds), aqueous dispersions of block copolymer micelles find numerous practical applications as nanocontainers for drugs [ 3 , 4 ], imaging and theranostic agents [ 5 , 6 , 7 , 8 , 9 , 10 ], nanoreactors for micellar catalysis [ 11 ] or nanoparticle synthesis [ 12 , 13 , 14 ], etc. Almost all of the aforementioned applications require an as narrow as possible size distribution of the nanoparticles.…”
