Summary: Dyed wastewater has a serious impact on living organisms and must be treated before being released into the environment. Metal organic frameworks (MOFs) have been proposed as the most effective method for dye wastewater removal due to their high adsorption capacity and adjustable pore diameter and surface morphology. This study aims to evaluate the effectiveness of different types of MOFs in dye separation from wastewater and includes the examination of adsorption isotherms, kinetics, and characterization studies. The desorption and reuse of MOFs are also considered.

Summary: A 2-dimensional Pb(ii) metal-organic framework (MOF) named SM-3 was synthesized using a mixed ligand approach under solvothermal conditions. SM-3 showed a 2D layered structure with unique interactions and exhibited excellent adsorption performance for iodine and dyes. It can reversibly adsorb radioactive iodine and selectively adsorb hazardous cationic dyes from aqueous solution. This work is remarkable for coordination chemists to engineer layered MOFs for adsorption purposes and enhance the adsorption of hazardous pollutants for environment protection.

Summary: Green synthesis of zinc(II) metal-organic framework (Zn-MOF) was achieved using spent domestic batteries as a source of Zn metal and benzene dicarboxylic acid as a linker. The synthesized Zn-MOF exhibited similar properties to those reported in literature and remained stable in water. The adsorption of three dyes onto the Zn-MOF followed a pseudo-second-order kinetic model and Freundlich isotherm model. Thermodynamic analysis revealed that the adsorption of one dye was endothermic and spontaneous, while the uptake of the other two dyes was non-spontaneous and exothermic. This study contributes to the development of value-added MOFs from solid waste.

Summary: Antibiotic resistance is a major concern and scientists have been searching for novel strategies to combat bacterial infections. The usage of Nisin Z, an antimicrobial peptide, is restricted due to its poor stability. In this study, cyclodextrin-based nanosponges were used as carriers for Nisin Z loading, which resulted in enhanced antimicrobial activity. The findings suggest that cross-linked beta-CD-based nanosponges have the potential to serve as carriers for delivering and enhancing the antibacterial action of Nisin Z.

Summary: Beta cyclodextrin-based polymers are attracting attention for their tunable synthesis, chemical stability, and biocompatibility. Researchers are exploring ecofriendly alternatives to toxic compounds and organic solvents for large-scale production. In this study, natural deep eutectic solvents (NADES) derived from low-cost compounds were used to produce water-soluble BCD-based polymers. The obtained solutions were electrospun into sub-micrometric fibers, which could be crosslinked without altering their morphology. The resulting fibrous mats were then used as bio-derived precursors to produce porous carbon fibers. The adsorption performances of both the cross-linked mats and carbon fibers were tested for the treatment of emerging pollutants in contaminated water.

Summary: This study investigated the use of cross-linked cyclodextrin nanosponges (CDNS) as a carrier for Nisin loading and its effect on melanoma cancer. Results showed that Nisin loaded in CDNS exhibited significant antitumor activity by increasing cytotoxicity and apoptosis in melanoma cancer cell lines. Moreover, Nisin loaded on PMDA-NSs demonstrated superior inhibitory effects on melanoma cancer growth in mouse models compared to free Nisin. The incorporation of Nisin into nanosponges improved its antitumor effect and increased apoptosis and antioxidant activity.

Summary: By studying the gene delivery process using Ppoly-pDNA nanocomplexes in 2D and 3D cell models, it was found that the transfection efficiency and cytotoxicity of Ppoly were lower in 3D spheroids compared to 2D monolayer cells. Additionally, histopathology visualization demonstrated that Ppoly could penetrate into the inner layers of 3D spheroids, indicating its potential as a non-viral gene delivery system with high encapsulation efficiency and good transfection efficiency.

Summary: Melatonin, a neurohormone, has many health benefits when used as a drug, but its fast release poses limitations. Cyclodextrin-based nanosponges (CD-based NSs) can overcome this issue by providing sustained release. Green cyclodextrin (CD)-based molecularly imprinted nanosponges (MIP-NSs) and non-molecularly imprinted nanosponges (NIP-NSs) were synthesized and characterized. MIP-NSs showed better-controlled drug release and higher encapsulation efficiency compared to NIP-NSs.
