“…With the focus on the assembly of simple, spherical particles, this review does not cover the synthesis and self-assembly of more complex colloidal building blocks, such as Janus particles, 34,35 patchy particles, [36][37][38][39] core-shell particles, [40][41][42] particles with more complex internal structures, [43][44][45] anisotropic particles, 46 or non-spherical nanocrystals. [47][48][49][50] Complex properties and highly functional materials can emerge solely by controlling the structure of the material or by providing a template to generate patterns in another material. The classical structures created by spherical assemblies are direct opals, consisting of threedimensional assemblies of colloidal particles in the ordered arrangement of a face centered cubic crystal ( Figure 3A), and their inverse analogues created by backfilling the interstitial sites with a second material and subsequent removal of the colloids which serve as templates to generate an interconnected, porous matrix ( Figure 3C).…”

Nature evolved a variety of hierarchical structures that produce sophisticated functions. Inspired by these natural materials, colloidal self-assembly provides a convenient way to produce structures from simple building blocks with a variety of complex functions beyond those found in nature. In particular, colloid-based porous materials (CBPM) can be made from a wide variety of materials. The internal structure of CBPM also has several key attributes, namely porosity on a sub-micrometer length scale, interconnectivity of these pores, and a controllable degree of order. The combination of structure and composition allow CBPM to attain properties important for modern applications such as photonic inks, colorimetric sensors, self-cleaning surfaces, water purification systems, or batteries. This review summarizes recent developments in the field of CBPM, including principles for their design, fabrication, and applications, with a particular focus on structural features and materials' properties that enable these applications. We begin with a short introduction to the wide variety of patterns that can be generated by colloidal self-assembly and templating processes. We then discuss different applications of such structures, focusing on optics, wetting, sensing, catalysis, and electrodes. Different fields of applications require different properties, yet the modularity of the assembly process of CBPM provides a high degree of tunability and tailorability in composition and structure. We examine the significance of properties such as structure, composition, and degree of order on the materials' functions and use, as well as trends in and future directions for the development of CBPM.

“…The nanoparticles have maintained their shape and size during the assemblage and calcination processes. With the development of reliable synthetic procedures 27,28 over the last decade allowing access to a range of transition and noble metal particles useful for catalysis using preformed nanoparticles in supported materials is readily achievable. Using these nanoparticles provides an avenue to more predictable samples than those obtained using traditional methods such as co-precipitation and sol-gel.…”

Preformed iron oxide nanoparticles have been successfully assembled onto alumina and MCM-41 support materials. The particles are found to disperse evenly over the surface of the silicate; however, in the case of the alumina we find that in addition to areas of even distribution there is also some clustering of the particles. The materials are stable under heat treatment, with no signs of further aggregation during calcination. We investigate the reducibility of the materials through H 2 -TPR studies and we find that the particles are reducible around 500-550 o C. The reduction process is complete at temperatures where MCM-41 can undergo degradation, supporting that the alumina based materials are more suited to the multiple base oxidation reduction steps in the catalytic cycle.

“…[40] Hence, fabrication of nanoparticles with small size and narrow size distribution need a homogenous reaction environment followed by ultrafast mixing. [43] A number of these challenges, particularly in the size control have been overcome by the batch synthesis routes [158] presented in the previous section. Although wet-chemical methods have been widely used, they are still suffering from some of their intrinsic properties.…”

In order to translate nanotechnology into medical practice, magnetic nanoparticles (MNPs) have been presented as a class of non‐invasive nanomaterials for numerous biomedical applications. In particular, MNPs have opened a door for simultaneous diagnosis and brisk treatment of diseases in the form of theranostic agents. This review highlights the recent advances in preparation and utilization of MNPs from the synthesis and functionalization steps to the final design consideration in evading the body immune system for therapeutic and diagnostic applications with addressing the most recent examples of the literature in each section. This study provides a conceptual framework of a wide range of synthetic routes classified mainly as wet chemistry, state‐of‐the‐art microfluidic reactors, and biogenic routes, along with the most popular coating materials to stabilize resultant MNPs. Additionally, key aspects of prolonging the half‐life of MNPs via overcoming the sequential biological barriers are covered through unraveling the biophysical interactions at the bio–nano interface and giving a set of criteria to efficiently modulate MNPs' physicochemical properties. Furthermore, concepts of passive and active targeting for successful cell internalization, by respectively exploiting the unique properties of cancers and novel targeting ligands are described in detail. Finally, this study extensively covers the recent developments in magnetic drug targeting and hyperthermia as therapeutic applications of MNPs. In addition, multi‐modal imaging via fusion of magnetic resonance imaging, and also innovative magnetic particle imaging with other imaging techniques for early diagnosis of diseases are extensively provided.
