“…11 An impressive strategy to improve the adsorption properties and reduce such aggregation while maintaining excellent magnetic responsiveness involves the relatively easy fabrication of core−shell nanostructured CuFe 2 O 4 magnetic nanocrystals as the hybrid functionalized materials by applying the biocompatible metal−organic framework (MOF) nanocrystals. 12,13 High porosity and specific surface area, numerous metal-binding sites, wider bore diameter, high surface functional groups, dual-function surfaces, facile large-scale synthesis, and functionalization features of MOFs have attracted much attention. 14,15 In the case of capturing cancer cells, there are a few reports using MIL and/or ferrite materials; among them, the following can be mentioned: Xie et al reported the Fe 3 O 4 @MIL-100(Fe) core−shell composite, which was modified by anti-EpCAM for the in vitro capture and release of CTCs.…”

Low number of circulating tumor cells (CTCs) in the blood samples and time-consuming properties of the current CTC isolation methods for processing a small volume of blood are the biggest obstacles to CTC usage in practice. Therefore, we aimed to design a CTC dialysis system with the ability to process cancer patients' whole blood within a reasonable time. Two strategies were employed for developing this dialysis setup, including (i) synthesizing novel in situ core−shell Cu ferrites consisting of the Cu-CuFe 2 O 4 core and the MIL-88A shell, which are targeted by the anti-HER2 antibody for the efficient targeting and trapping of CTCs; and (ii) fabricating a microfluidic system containing a three-dimensional (3D)-printed microchannel filter composed of a polycaprolactone/Fe 3 O 4 nanoparticle composite with pore diameter less than 200 μm on which a high-voltage magnetic field is focused to enrich and isolate the magnetic nanoparticle-targeted CTCs from a large volume of blood. The system was assessed in different aspects including capturing the efficacy of the magnetic nanoparticles, CTC enrichment and isolation from large volumes of human blood, side effects on blood cells, and the viability of CTCs after isolation for further analysis. Under the optimized conditions, the CTC dialysis system exhibited more than 80% efficacy in the isolation of CTCs from blood samples. The isolated CTCs were viable and were able to proliferate. Moreover, the CTC dialysis system was safe and did not cause side effects on normal blood cells. Taken together, the designed CTC dialysis system can process a high volume of blood for efficient dual diagnostic and therapeutic purposes.

“…The cost-effective value of the adsorbing approach, along with its ability to efficiently remove dyes, including Congo red, renders it a highly endorsed elimination technique. This approach offers advantages such as excellent eliminating capacity, wide applicability, simplistic recovery and recycling capacity, and affordable manufacturing practices. , Therefore, various types of mono and hybrid structures have been explored to develop effective adsorption agents against dyes. ,, Nevertheless, the key considerations in selecting the most appropriate adsorbents are their manufacturing expenses, natural abundance, rapid kinetic rates, retention effectiveness, adsorption specificity, and reuse and recovery values …”

Zeolite-A was synthesized successfully from kaolinite and hybridized with two species of biopolymers (chitosan (CH/ Z) and β-cyclodextrin (CD/Z)). The obtained hybridized forms were assessed as potential adsorbents of Congo red synthetic dye (CR) with enhanced affinities and elimination capacities. The synthesized CD/Z and CH/Z hybrids demonstrated uptake capacities of 223.6 and 208.7 mg/g, which are significantly higher than single-phase zeolite-A (140.3 mg/g). The integrated polymers change the surface area, surface reactivity, and number of free active receptors that are already present. The classic isotherm investigations validate Langmuir equilibrium behavior for ZA and Freundlich properties for CD/Z and CH/Z. The steric parameters validate a strong increase in the existing active receptors after the incorporation of CD (CD/Z) to be 98.1 mg/g as compared to 83 mg/g for CH/Z and 60.6 mg/g for ZA, which illustrate the detected uptake behaviors. Moreover, the CR dye was adsorbed as several molecules per single site, reflecting the vertical uptake of these molecules by multimolecular mechanisms. The energetic assessment, considering both Gaussian energies and adsorption energies (<40 kJ/mol), validates the dominant impact of the physical mechanism during the sequestration of CR (dipole binding interactions (2−29 kJ/mol) and hydrogen bonds (<30 kJ/mol)), in addition to the considerable effect of ion exchange processes. Based on the thermodynamic parameters, the CR molecules were adsorbed by exothermic and spontaneous reactions.

Facile approach has been employed for the synthesis of new copper ferrite impregnated sulfonated graphene oxide (SGO) nanocomposite via co‐precipitation technique. The newly created nanocomposite has exceptional qualities like a strong stability, large surface area, simple as well as effective recoverability. Structure, composition, and morphology of CuFe2O4@SGO nanocomposite were analyzed by fourier‐transform infrared spectroscopy (FT‐IR), scanning electron microscope (SEM), energy dispersive X‐Ray (EDX), X‐ray diffraction (XRD), and thermogravimetric analysis (TGA) techniques. The results presented the decoration of CuFe2O4 nanoparticles decorated uniformly upon the SGO sheets. Presently, photocatalytic efficiency of synthesized nanocomposite has been assessed for the deterioration of methyl violet 2B (MV) dye. On the effectiveness of dye degradation, the impacts of variables including initial dye concentration, catalyst loading, and visible light exposure have been studied. The photocatalytic data show that 97% of dye was degraded in merely 90 min. CuFe2O4@SGO nanocomposite was easily recyclable and hence it shows future scope as an inexpensive and alternate approach for removal of dye. The results of antimicrobial data evaluated that outstanding antibacterial data counter to Escherichia coli, Bacillus subtilis, and excellent antifungal data counter to Candida albicans was perceived.
