“…The structures of these clusters are shown in Figure 3, similar to previous studies. 43,44 The configurations and adsorption energies are also summarized in Figure 3 Previous studies reported 45,46 that a Cd−thiol complex surface layer was created as a shell around the CdTe QDs core to occupy the surface sites and to passivate the QDs. In addition, the binding force of Cd−Se bond was much greater than that of Cd-thiol.…”

With the development of nanoscience and nanotechnology, manufacturing is undergoing revolutionary changes. Nanoparticles, due to their novel and often enhanced properties, are now more and more used in manufacturing. In this chapter, the state-of-the-art application of nanoparticles in manufacturing is reviewed. The contents include five parts: (a) role of nanoparticles in manufacturing, (b) manufacturing methods, (c) applications, (d) challenges, and (e) conclusions. The roles of nanoparticles are divided into three categories: (i) building blocks, being the major component of a manufactured product by solid-state or colloidal nanoparticle consolidation; (ii) functional filler, as an addition for functionality, such as property improver, catalyst, stimuli-responsive, sensing, imaging, and carrier; and (iii) nanocomposites for multifunctionality. Various manufacturing methods and novel trends are summarized in this chapter, including top-down and bottom-up, from 2D to 3D, from cleanroom to desktop, 3D printing, and bio-assisted methods, such as DNA origami. Direct applications in areas of flexible electronics, molecular electronics, solar cells, construction industry, water treatment, and biomedical devices are presented. The associated challenges including nanoparticle safety issue, sustainable manufacturing, economic issue, and scale-up are discussed. Role of Nanoparticles in ManufacturingWith the development of nanoscience and nanotechnology, manufacturing is undergoing revolutionary changes. Nanoparticles, due to their novel and often enhanced properties, have more and more been used in various manufacturing applications. Their role can generally be divided into three categories: (a) building blocks, (b) functional filler, and (c) nanocomposites for multifunctionality, which is summarized in Table 1. Building BlockNanoparticles sometimes act like the bricks in a house-building process to be the main component of a manufactured product. They can be consolidated via solid-and liquid-based methods. Solid-State Nanoparticle ConsolidationSolid-state metallic, ceramic, amorphous, and compound particles can be thermomechanically processed to form bulk 2D/3D structures with desired strength and level of densification (even full densification is possible). Reported methods include powder compact forging/extrusion, equal channel angular extrusion/ pressing, and hot pressing/sinter forging combined with conventional heating, laser sintering, microwave sintering, electric discharge sintering, or spark plasma sintering [33,255,278,306,425,426,476,492]. Particles with a narrow size distribution and spherical shape are desired to achieve low pore-to-

“…QDs are a new class of fluorescent probes for molecular imaging with unique photophysical properties, such as size‐tunable light emission, high signal brightness, simultaneous excitation of multiple fluorescence colors, and resistance against photobleaching 89. QDs are another versatile type of nanocarriers that contain dual‐imaging and therapeutic functions to overcome drug resistance of cancers.…”

Cancer multidrug resistance (MDR) could lead to therapeutic failure of chemotherapy and radiotherapy, and has become one of the main obstacles to successful cancer treatment. Some advanced drug delivery platforms, such as inorganic nanocarriers, demonstrate a high potential for cancer theranostic to overcome the cancer‐specific limitation of conventional low‐molecular‐weight anticancer agents and imaging probes. Specifically, it could achieve synergetic therapeutic effects, demonstrating stronger killing effects to MDR cancer cells by combining the inorganic nanocarriers with other treatment manners, such as RNA interference and thermal therapy. Moreover, the inorganic nanocarriers could provide imaging functions to help monitor treatment responses, e.g., drug resistance and therapeutic effects, as well as analyze the mechanism of MDR by molecular imaging modalities. In this review, the mechanisms involved in cancer MDR and recent advances of applying inorganic nanocarriers for MDR cancer imaging and therapy are summarized. The inorganic nanocarriers may circumvent cancer MDR for effective therapy and provide a way to track the therapeutic processes for real‐time molecular imaging, demonstrating high performance in studying the interaction of nanocarriers and MDR cancer cells/tissues in laboratory study and further shedding light on elaborate design of nanocarriers that could overcome MDR for clinical translation.
