“…Despite these successes, PMS materials have an important shortcomingtheir synthesis process requires rather harsh conditions (high temperature and pressure, very high or very low pH, toxic chemicals), resulting in unsustainable methods that cannot be adopted economically at industrial scales. This opened up a new area of research aiming to produce controlled nanoporous silica materials using environmentally friendly synthesis conditions [7,8]. Shortly after the discovery of PMS, Tanev and Pinnavaia [9] made the first attempt towards this goal by synthesising Hexagonal Mesoporous Silica (HMS) materials using alkylamines as templates instead of ammonium surfactants, based on a hypothesised "neutral templating mechanism".…”

“…Interestingly, amine-rich peptides and long-chain polyamines have later been shown to play a crucial role in directing the porous structure formation in biosilicification by marine organisms like diatoms and sponges [10][11][12], a process that leads to the formation of hierarchical structures of amazing beauty and complexity at very mild conditions of pressure, temperature and pH. Currently, amine-based "additives" are at the core of the rapidly expanding field of bio-inspired silica synthesis, which aims to adapt the principles of biosilicification to produce synthetic silica materials of controlled porosity under mild conditions with a low environmental footprint [8,13].…”

“…The main bottleneck hindering further progress in this field is the lack of in-depth understanding of the underlying mechanism of amine-templated silica synthesis [4,8]. In this paper, we shed new light on this issue through a combination of experimental studies and multi-scale modelling, focussing on HMS [9] as the first example of synthetic aminetemplated silica material.…”

“…Further, by combining the findings reported herein with the recent developments on room temperature synthesis of porous silica [8] and eco-friendly removal of templates [43] has the potential to deliver commercially viable manufacturing routes to porous materials. Research along these lines is currently being explored in our laboratories.…”

“…In recent years, the development of the new nanomaterials and the nanoscience study has cobranded a preponderant place due to the wide number of researchers carried out in those fields. This is due to the notables physic, chemical, magnetic, optical, electronic and catalytic properties exhibits by the materials at the nanometric scale [1][2][3]. The quantic confinement of the atoms on the nanoparticles favors the reactivity of the nanoparticles, given as results better properties associated with de nanoparticles in relationship to the bulk materials.…”

Currently, the use of sustainable chemistry as an ecological alternative for the generation of products or processes, free of polluting substance has assumed a preponderant role. The aim of this work is propose a bioinspired, facile, at low cost, non-toxic and environmentally friendly alternative to obtaining magnetic nanoparticles whit a majority phase of magnetite (Fe3O4). Is important to empathize that the synthesis was based on the chemical reduction through the Cnicus Benedictus extract, whose use as reducing agent has not been reported in the synthesis of iron oxides nanoparticles. In addition, the Cnicus Benedictus is abundant endemic plant in Mexico, with several medicinal properties and a large number of natural antioxidants. The obtained nanoparticles exhibited significant magnetic and antibacterial properties and an enhanced photocatalytic activity. The crystallite size of the Fe3O4 nanoparticles (Fe3O4 NP’s) was calculated by Williamson-Hall method. The photocatalytic properties of the Fe3O4 NP´s were studied by kinetics absorptions models in the Congo red (CR) degradation. Finally the antibacterial effect of the Fe3O4 NP´s were evaluated mediated the Kirby-Bauer method against E. coli and S. aureus bacteria. This route offers a green alternative to obtain Fe3O4 NP´s with remarkable magnetic, photocatalytic and antibacterial properties.

improving the flexibility and adaptability based on the concepts of bioinspired structures, bioinspired synthesis, bioinspired functionalization, and bioinspired integration. For the studies on the natural species from the point of view of materials and chemistry, the research primarily focuses on three aspects: the real-time observation on the unique phenomena (e.g., drop condensation and water repelling), the in-depth examination on the constitutional structures (e.g., multiscale micro-/nano-structures and inorganic/ organic hybrids), and the comprehensive understanding on the functional mechanisms (e.g., nerve conduction and preys capture). For example, as one of most studied natural structures, nacre, a brickand-mortar structure composed of brittle inorganic calcium carbonate (95 vol%) and soft organic chitin and proteins (5 vol%), exhibits extraordinary tolerance and fracture toughness, which offers us inspirations on designing strong but tolerant materials from conventional weak and brittle raw materials. [8] The studies on the unique properties and structures with an understanding on the structure-property-functionality relationship of the natural species are a basic prerequisite for the design of bioinspired artificial materials and systems. Different to biomaterials that are made from either natural or synthetic materials for interacting with biological systems and primarily targeted for direct medical application or therapeutic or diagnostic purposes, bioinspired materials are artificial functional or engineering materials that are rationally designed by learning from the inspiring structural or functional features of the natural creatives or species for the applications as advanced materials in mechanical enhancement, chemical reactions, sensing, healthmonitoring, etc.On the other hands, to well design the bioinspired materials, omni-directional knowledge on the on-demand synthesis, hierarchical ordering organization, and intrinsic chemical/ physical properties of the building blocks is highly required. Specifically, a bioinspired structure is expected to bring about new bioinspired functionalities from the bioinspired structures. Therefore, to bridge the link between the structures and the functionalities, the capacity to synthesize the bioinspired materials with desired morphology and multiscale ordering is essential and crucial. For example, as one typical wide-gap inorganic material, ZnO has been employed in various applications ranging from optical material to building material. The conventional forms of ZnO in either powders or coatings only display the colors of white or colorless. However, if self-assembly the Nature offers a variety of interesting structures and intriguing functions for researchers to be learnt for advanced materials innovations. Recently, bioinspired materials have received intensive attention in energy storage applications. Inspired by various natural species, many new configurations and components of energy storage devices, such as rechargeable batteries and supercapacitors...
