“…Moreover, MOF particles can be synthesized in nanosized range while giving them antifungal activity (Figure 1). Thus, NPs of UiO-66 (zirconium-based MOFs, 68.4 ± 8.5 nm) when injected into a medium with white rot fungus Phanerochaete chrysosporium showed a weak effect on cells and did not penetrate them but slightly damaged the cell wall and inhibited the activity of the laccase secreted by them [46].…”

Active research of metal-containing compounds and enzymes as effective antifungal agents is currently being conducted due to the growing antifungal resistance problem. Metals are attracting special attention due to the wide variety of ligands that can be used for them, including chemically synthesized and naturally obtained variants as a result of the so-called “green synthesis”. The main mechanism of the antifungal action of metals is the triggering of the generation and accumulation of reactive oxygen species (ROS). Further action of ROS on various biomolecules is nonspecific. Various hydrolytic enzymes (glucanases and proteases), in turn, exhibit antifungal properties by affecting the structural elements of fungal cells (cell walls, membranes), fungal quorum sensing molecules, fungal own protective agents (mycotoxins and antibiotics), and proteins responsible for the adhesion and formation of stable, highly concentrated populations in the form of biofilms. A wide substrate range of enzymes allows the use of various mechanisms of their antifungal actions. In this review, we discuss the prospects of combining two different types of antifungal agents (metals and enzymes) against mycelial fungi and yeast cells. Special attention is paid to the possible influence of metals on the activity of the enzymes and the possible effects of proteins on the antifungal activity of metal-containing compounds.

“…Owing to their topological structural tunability, high specific area, facile preparation, and designable functionality, MOFs have gained extensive attraction in the field of adsorption. Compared with the other emerging adsorbents, such as covalent organic frameworks, hypercrosslinked polymers, and nanosilica composites, MOFs exhibit excellent advantages in terms of environmental friendliness, toxicity, and production costs. − To date, various well-defined MOFs have been synthesized and utilized in adsorption of REEs. For example, an investigation reported that a Cu-based MOF (HKUST-1) exhibited a remarkable adsorption capacity of 353 mg/g for Ce(III) because of its innate porosity and large specific surface area .…”

The recovery of rare earth elements (REEs) from discharged electronic devices or mineral waste water is highly essential but still facing challenges. In this work, two amino-functionalized carboxyl-UiO-66 (UiO-66-COOH-TETA and UiO-66-(COOH) 2 -ED) prepared via the postmodification method were employed as the adsorbents for Yb(III) capture. The experimental results revealed their superior adsorption capacities of 161.5 and 202.6 mg/g, respectively. Meanwhile, their adsorption processes can be described by the pseudosecond-order kinetic model and Langmuir model. Effects of initial pH and temperature on adsorptions were systematically evaluated, affording an optimal operating condition (i.e., pH of 5.5−6, T of 65 °C, t of 10 h). Moreover, the fabricated materials exhibited great reusability after five adsorption−regeneration cycles. UiO-66-COOH-TETA demonstrated good separation selectivity for Yb(III) over light REEs (i.e., 3.98 of Yb/ Ce, 3.51 of Yb/Nd). Based on the density functional theory calculations and characterization analysis (XPS, Zeta, mapping, and IR), the adsorption mechanisms were mainly attributed to significant electrostatic attraction and strong surface complexation between N and O sites and Yb(III).
