“…Up to now, various synthetic techniques such as spray drying [14,20], interfacial polymerization [21,22], self-assembly [5,11], layer-by-layer (LBL) fabrication [23,24], and templating have been established for making hollow silica particles. Among these methods, the templating method is popular, which uses polymeric spheres [8][9][10][25][26][27], micelles [6,28], droplets [7,[29][30][31], and inorganic particles [3,16,19] as templates.…”

“…Besides, reaction condition control for particle nucleation and growth from RTD, reactant concentration, or temperature in the microreactors is also important 37b,104. By carefully designing the component, concentration and temperature, complex particle structures, including hollow, rod, donut, and raspberry, can also be made. In different kinds of oxide materials, magnetic nanoparticles keep attracting researchers in recent years.…”

Modern nanotechnologies bring humanity to a new age, and advanced methods for preparing functional nanocrystals are cornerstones. A considerable variety of nanomaterials has been created over the past decades, but few were prepared on the macro scale, even fewer making it to the stage of industrial production. The gap between academic research and engineering production is expected to be filled by flow chemistry technology, which relies on microreactors. Microreaction devices and technologies for synthesizing different kinds of nanocrystals are discussed from an engineering point of view. The advantages of microreactors, the important features of flow chemistry systems, and methods to apply them in the syntheses of salt, oxide, metal, alloy, and quantum dot nanomaterials are summarized. To further exhibit the scaling‐up of nanocrystal synthesis, recent reports on using microreactors with gram per hour and larger production rates are highlighted. Finally, an industrial example for preparing 10 tons of CaCO3 nanoparticles per day is introduced, which shows the great potential for flow chemistry processes to transfer lab research to industry.

“…[34] Chang et al [27] have shown a high perspective of w/o microemulsion method in synthesis of enzyme-encapsulated hollow silica particles. [35] The dispersed aqueous phase containing ammonia and CTAB was slowly injected into the inlet of the cross-flow microfluidic device in order to fabricate uniform water-oil droplets which further interact with TEOS forming silica microspheres. After the TEOS and aqueous solution were introduced, the w/o mixture was stirred for 8 h at 20 °C to form enzyme-incorporated silica nanoparticles.…”

Polyelectrolyte (PE) and nanocomposite (NC) microcapsules fabricated by layer‐by‐layer technique have been of great interest in the past decade as novel entities for cargo encapsulation and delivery as well as for diagnostic purposes. The unique physicochemical properties of polymers and inorganic nanoparticles used in layer‐by‐layer synthesis of PE and NC microcapsules make them promising in various fields, such as storage, catalysis, cells imaging, controlled drug release, and targeted drug delivery. However, the requirement of the cargo encapsulation is that the cargo should have a relatively large molecular weight in order to avoid the leakage from the capsules. In this review, recent progress in the design and functionalization of PE and NC microcapsules using sol–gel method for storage of small cargos have been presented. Moreover, various remote exposures on the permeability of organic/inorganic composite microcapsule shells such as ultrasound, magnetic field gradient, laser, and microwave radiation have been observed. Finally, the description and discussion of the new trends and perspectives for improved functionality of PE microcapsules are the major topic of this progress report.
