“…Porous oxides are significant supports for nanoparticles of catalytic interest, and an adequate porous distribution favors the adsorption and diffusion of the reagents. Figure 4A shows aminefunctionalized corrugated silica spheres with a hierarchical meso/ macroporous system, which have been used to support enzymes of biotechnological interest (Fuentes et al, 2020). Functionalization occurred in the mesopores distributed through the wrinkled walls, and the conservation of macropores facilitated the diffusion of enzymes inside the particles.…”

The current challenges in developing novel nanotechnological processes have led us to explore new methods for synthesizing nanomaterials whose functionalities rely on their structural complexity. In this respect, nature has always been a source of inspiration for proposing innovative technologies to improve the quality of life. Hierarchical superstructures (HSS) are of great interest because the self-assembly of low-dimensional nanostructures (up to the macroscale) allows the control and optimization of performance by coupling the properties of the individual blocks. Self-assembled surfactant structures are convenient for HSS synthesis because they provide a confined reaction medium which confers excellent control over the size of the building blocks. Furthermore, bicontinuous microemulsions offer a soft three-dimensional template due to their interconnected nature. Similarly, electrodeposition routes offer fast, robust, clean, and reproducible ways to synthesize metallic and multimetallic HSS. The combination of soft-templating and electrodeposition is a powerful tool for controlling the morphology and composition of the material. This work reviews polymeric, ceramic, and metallic hierarchical superstructures synthesized using bicontinuous microemulsions and electrodeposition techniques and compares them with matching natural patterns. The aim is to show how these synthetic routes can be exploited to obtain efficient biomimetic nanomaterials that improve their properties.

“…Mesoporous silica nanoparticles are attractive as drug delivery vehicles for cancer therapy due to the potential high loading capacity of anticancer drugs . WMS has effectively been loaded with doxorubicin, ,, cisplatin, glucosidases, , laccase, lipase, and cytochrome monooxygenases . Silica can also be used to encapsulate inorganic materials such as metal oxide nanoparticles. , Previously, the encapsulation of nanoparticles in silica has been attempted using the Stöber process.…”
