Special Issue Information

Dear Colleagues,

Colloidal nanoparticles are transforming many research fields, from energy conversion to biomedicine. The size/shape- and composition-dependent physicochemical properties of inorganic materials and their large surface area, which regulates interaction at the interface, highlight the strong relationship between structure and property (hence function) at the nanoscale and push towards a selective design of the materials. In this regard, colloidal nanoparticles that are synthesized in solution can take advantage of the principles of colloidal chemistry for the development of synthetic strategies able to offer a high control of their morphology, composition, and surface chemistry. Since these artificial colloidal nanoparticles are dispersible in solution, they can be manipulated like molecules, and molecular reaction or interaction can be specifically exploited for the material’s surface functionalization. In this regard, this Special Issue aims at highlighting diverse aspects of materials at the nanoscale, spanning from the synthesis of different classes of colloidal nanoparticles to their surface engineering, towards properly designed nanostructures with tailored functional properties and, consequently, as active components that can be useful for applications in the field of energy conversion, catalysis, sensing, and biomedicine. We want to encourage scientists of diverse backgrounds (material science, inorganic chemistry, biochemistry, biology) to contribute cutting-edge research papers, communications, and review articles to this Special Issue of Nanomaterials.

Title: Silica nanoparticles as inner-sphere ligands of Co2+ ions. Impact of synthetic technique on geometry of inner-sphere polyhedron and electrochemical activity of the nanoparticles

Abstract: The present work introduces both synthesis of silica nanoparticles doped with CoII ions by means of differently modified microemulsion water-in-oil and Stöber techniques and characterization of the hybrid nanoparticles ([email protected]) by TEM, DLS, XRD, ICP-EOS, SAXS, UV-Vis and UV-Vis/DR spectroscopy and electrochemical methods. The results reveal the lack of any nanocrystalline dopants inside the hybrid nanoparticles, as well as no ligands, when CoII ions are added to the synthetic mixtures as CoII(bpy)3 complexes, thus, pointing to coordination of CoII ions with silica matrix as the main driving force of the doping. The use of microemulsion or Stöber technique is of great impact on cobalt content and surface porosity of the hybrid nanoparticles. Comparison of UV-Vis/DR spectra also revealed the difference in the spectral patterns of [email protected] synthesized by the different techniques. The aforesaid differences are correlated with electrochemical activity of CoII ions, which is greatly enhanced by organophosphorus compounds. Its application for the determination of organophosphorus compounds is also demonstrated.

Title: Multifunctional non-epitaxial Nanostructures for diagnosis and therapy

Abstract: Well-designed combination of two or more inorganic nanoparticles (NPs) in a single hierarchically organized nanostructure allows the simultaneous exploitation of multiple properties, such as luminescence, photo-activity or magnetism, deriving from each component. Two main preparative approaches can been explored for the preparation of the multidomain nanomaterials: the epitaxial growth of a second domain onto seeds of pre-existing one and the non-epitaxial growth. While the epitaxial growth requires advances in solution-based synthesis and heterostructure properties are strongly affected by lattice mismatch at the two domains interface, the non-epitaxial growth generates the complex hybrid nanostructures by simply joining and assembling discrete groups of distinct pre-synthesized NPs, regardless of structural parameters of each single NP. Bridging molecules, interacting surface moieties/ligands, or glues via polymer sections can be used for this purpose. This review intends to give an overview of the main preparative strategies and properties of non-epitaxial nanostructures proposed for applications in biomedicine. Indeed, multicomponent nanostructures can be functionalized with specific biomolecules to achieve original bioconjugates with great potential in diagnosis and/or therapy of several diseases. The NPs properties will be extensively described, to better understand the effective advantage offered by each individual function when integrated in a single nanostructure. Representative examples of bifunctional (magnetic/plasmonic, or magnetic/fluorescent or plasmonic/fluorescent) non epitaxial nanostructures, investigated for diagnosis and therapy of specific diseases, will be presented and listed according to the strategy used to assemble the discrete groups of distinct NPs.
