Special Issue Information

Dear Colleagues,

The development of new methods for the nanostructuration of molecular units to build inorganic materials constitutes one of the basic pillars of the current advances in nanotechnology. It is well known that most material properties, such as mechanical, electric, magnetic, optical, and chemical strongly depend on the particle shape, size, and surface. For these reasons, the controlled nanostructuration of materials has paved the way for the development of new applications, as well as improvements to existing ones.

Inorganic nanostructures attract research interest in a broad range of fields for several reasons. In particular, biomedical applications benefit from the fact that nanostructures possess the size in which most of the biomolecular interactions take place. Moreover, the incorporation of specific moieties to the nanostructure surface opens new possibilities for targeting, sensing, and imaging, among others, and also offers enhanced stabilities and reduced toxicity. In catalysis, inorganic nanostructures are relevant due to their electronic properties, which are at the frontier between the molecular and metallic states, as well as the high proportion of surface atoms giving rise to numerous active sites. Other examples are natural inorganic nanostructures such as clay-based nanocomposites, which show excellent adsorption and biocompatible properties, and are great sustainable alternatives for the removal of pollutants from diverse sources, when compared to other toxic or expensive artificial materials currently employed.

This Special Issue will be focused on the nanostructuration of molecular units to build inorganic materials. It will also cover the development of functionalization approaches to impart such nanostructures with additional functionalities, as well as the comprehensive investigation of material properties and their potential applications. This Special Issue will promote the exchange of ideas and knowledge among researchers in the fields of chemistry, materials science, biology, and biomedicine.

Chemical routes for the synthesis of nanostructures are fundamental in nanoscience. Among the different strategies for the production of nanostructures, this article reviews the fundamentals of the bottom-up approaches, focusing on wet chemistry synthesis. It offers a general view on the synthesis of different inorganic and hybrid organic–inorganic nanostructures such as ceramics, metal, and semiconductor nanoparticles, mesoporous structures, and metal–organic frameworks. This review article is especially written for a wide audience demanding a text focused on the basic concepts and ideas of the synthesis of inorganic and hybrid nanostructures. It is styled for both early researchers who are starting to work on this topic and also non-specialist readers with a basic background on chemistry. Updated references and texts that provide a deeper discussion and describing the different synthesis strategies in detail are given, as well as a section on the current perspectives and possible future evolution.

Nanoclays are widespread materials characterized by a layered structure in the nano-scale range. They have multiple applications in diverse scientific and industrial areas, mainly due to their swelling capacity, cation exchange capacity, and plasticity. Due to the cation exchange capacity, nanoclays can serve as host matrices for the stabilization of several molecules and, thus, they can be used as sensors by incorporating electroactive ions, biomolecules as enzymes, or fluorescence probes. In this review, the most recent applications as bioanalyte sensors are addressed, focusing on two main detection systems: electrochemical and optical methods. Particularly, the application of electrochemical sensors with clay-modified electrodes (CLME) for pesticide detection is described. Moreover, recent advances of both electrochemical and optical sensors based on nanoclays for diverse bioanalytes’ detection such as glucose, H2O2, organic acids, proteins, or bacteria are also discussed. As it can be seen from this review, nanoclays can become a key factor in sensors’ development, creating an emerging technology for the detection of bioanalytes, with application in both environmental and biomedical fields.
