“…However, because of their high surface energy, the challenge of chemically preparing metal nanocrystals with high-index facets remains. In 2008, Sun and co-workers [43] reported a structure-functionality relationship of Au NCs. They obtained star-shaped Au NPs in deep eutectic solvents bounded with (331) and vicinal high-index facets.…”

Catalysis Based on Nanocrystals with Well‐Defined Facets

Using bottom-up chemistry techniques, the composition, size, and shape in particular can now be controlled uniformly for each and every nanocrystal (NC). Research into shape-controlled NCs have shown that the catalytic properties of a material are sensitive not only to the size but also to the shape of the NCs as a consequence of well-defined facets. These findings are of great importance for modern heterogeneous catalysis research. First, a rational synthesis of catalysts might be achieved, since desired activity and selectivity would be acquired by simply tuning the shape, that is, the exposed crystal facets, of a NC catalyst. Second, shape-controlled NCs are relatively simple systems, in contrast to traditional complex solids, suggesting that they may serve as novel model catalysts to bridge the gap between model surfaces and real catalysts.

“…These nanoparticles are manufactured from a wide range of materials and also vary in flexibility. Using different methods, particles are generated with two-dimensional polygonal shapes [60–67], three-dimensional polyhedral shapes [68–72], rod shapes [73–79], branched structures [80–83], and other complex shapes such as snowflakes [81], flowers [81], thorns [81], hemispheres [84, 85], cones [85, 86], urchins [87, 88], filamentous particles [52], biconcave discoids [89], worms [8], trees [90], dendrites [91], necklaces [92], and chains [9, 55, 93, 94]. Importantly, the ability to produce drug product with a high level of consistency and reproducibility is critical in the pharmaceutical industry.…”

“…Along those lines, adjusting existing methods can fabricate both spherical and non-spherical nanoparticles with similar ease. For example, the gold nanoparticle synthesis method employing deep eutectic solvents (DES) produces a wide variety of different particle shapes through small adjustments in stoichiometry [81]. Another top-down fabrication method, Particle Replication in Non-wetting Templates (known as PRINT), uses lithography to produce nanoparticles of all shapes with the same ease [95].…”

Summary Recent advances in nanoparticle technology have enabled the fabrication of nanoparticle classes with unique size, shape, and materials, which in turn has facilitated major advancements in the field of nanomedicine. More specifically, in the last decade, nanoscientists have recognized that nanomedicine exhibits a highly engineerable nature that makes it a mainstream scientific discipline, which is governed by its own distinctive principles in terms of interactions with cells and intravascular, transvascular and interstitial transport. This review focuses on recent developments and understanding of the relation between the shape of a nanoparticle and its navigation through different biological processes. Importantly, we seek to illustrate that the shape of a nanoparticle can govern its in vivo journey and destination dictating its biodistribution, intravascular and transvascular transport, and ultimately targeting of difficult-to-reach cancer sites.

“…They are easily obtained from widely available components that exhibit low toxicity, do not need further purification, and in the best cases are biodegradable. DESs have been used in nanoparticle fabrication [9][10][11] and recently in nanocellulose fabrication. [12][13][14][15] In this study, a DES based on imidazole and triethylmethylammonium chloride (TEMACl) was used as a reaction medium for the chemical modification of nonbleached mechanical pulp (groundwood pulp, GWP).…”
