Special Issue Information

Dear Colleagues,

During the last two decades, gold complexes have developed into an important class of new compounds which are engaged in biomedical and catalytic applications and in many other areas, thus attracting ever-growing attention from the scientific community.

This Special Issue is aimed at highlighting the most recent advances on gold coordination chemistry, as well as on the application of gold complexes. Therefore, for this Special Issue, we welcome contributions related to all aspects of this topic, covering novel synthesis, reactivity, advanced applications (for example, in catalysis, bioinorganic chemistry, material science), as well as mechanistic or thoretical studies, showcasing the variety and versatility of gold compounds achieved to date.

A fascinating aspect of gold coordination chemistry is that it is rapidly and continuously developing. In this regard, special attention will be given to the most recent and innovative aspects of gold coordination chemistry. In fact, in addition to papers dealing with traditional molecular complexes, particularly encouraged is the submission of contributions dealing with nonconventional interaction modes of gold centres (aurophilic interaction, hydrogen bonds, etc.), with ligand stabilized multinuclear gold compounds/gold nanoclusters, with supramolecular architechtures based on gold, and of course with the properties and potential applications of the resulting adducts. Thus, this Special Issue will also serve as a way of opening up new opportunities for sharing knowledge and promoting collaborations between researchers dealing with the different facets of this complex field today.

Short review articles, full papers, and communications are all welcome.

Macroalgae are sources of bioactive compounds that are interesting from both a chemical and a medical point of view. Although their use in biomedicine has increased significantly in recent years, tests conducted to date have been mostly related to species from temperate latitudes, with the potential application of Antarctic biodiversity being minor. The wide variety of algae species present on Antarctic coastal areas can be a source of new antioxidants. Bearing this in mind, the brown macroalgae Desmarestia antarctica (DA) and the red Iridaea cordata (IC) were selected for the preparation of aqueous extracts with the aim of analyzing their antioxidant activity. This analysis was performed by determining reducing power, total phenolic content, and 2,2-diphenyl-1-picrylhydrazyl free radical scavenging activity. Furthermore, both extracts were employed to synthesize gold and silver nanoparticles. The nanomaterials were fully characterized by means of UV-Visible spectroscopy, transmission electron microscopy, Z potential measurements, and Fourier transform infrared spectroscopy, which confirmed the formation of stable, spherical nanoparticles with mean diameters of 13.7 ± 3.1 and 17.5 ± 3.7 nm for [email protected] and [email protected] and 12.6 ± 1.9 and 12.3 ± 1.6 nm for [email protected] and [email protected] Antioxidant assays were performed after the synthesis of the nanomaterials to evaluate their possible synergistic effect with the extracts. The results suggest that polysaccharides and proteins may play a key role in the process of reduction and stabilization. Finally, for the sake of comparison, the results obtained for the Antarctic macroalgae Desmarestia menziesii and Palmaria decipiens have also been considered in the present work. Full article
