The dispersal of production waste significantly impacts this problem. By in-situ polymerizing pyrrole on CoFe₂O₄ nanoparticles, a polypyrrole-coated cobalt ferrite (PPy@CoFe₂O₄) magnetic nanosorbent is synthesized to achieve effective removal of As(III). XRD data corroborated the findings of the SEM examination, which showed spherical nanoparticles with diameters of about 50 nm. Spinel ferrite production was suggested by the FTIR spectra, which showed clear peaks in the 400–600 cm^− 1 region, confirming the evidence of M–O bonds. The optimal removal of As(III) (99%) occurred at a pH of 6.0 to 7.0, with an adsorbent dosage of 40 mg. PPy/CoFe₂O₄ demonstrates a maximal monolayer adsorption capacity of 201.4 mg g^⁻1 under optimum conditions (330 K temperature, 40.0 mg adsorbent dose, and pH 6.0). Adsorption followed a pseudo-second-order kinetic model with an equilibrium time of 210 min. The adsorption isotherms were accurately represented by the Langmuir model. The removal efficiency was still higher than 94% following the five adsorption-desorption cycles. The adsorption of As(III) by PPy@CoFe₂O₄ is strongly influenced by pH of the medium. Electrostatic interaction is likely the main mechanism of As(III) adsorption onto PPy/CoFe₂O₄. The adsorption of As(III) onto PPy/CoFe₂O₄ takes place spontaneously, as indicated by a negative ΔG°. The results indicate that the PPy/CoFe₂O₄ composite functions as a highly efficient adsorbent, showcasing extensive applicability in the treatment of wastewater contaminated with heavy metal ions.</p>\u0000 </div>","PeriodicalId":638,"journal":{"name":"Journal of Inclusion Phenomena and Macrocyclic Chemistry","volume":"105 11-12","pages":"593 - 606"},"PeriodicalIF":1.6,"publicationDate":"2025-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145646341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have previously developed a fluorophenyl boronic acid-modified polyrotaxane (FPBA-PRX), as a novel supramolecular boron compund for BNCT. FPBA in FPBA-PRX binds to sialic acid, which is highly expressed on the surface of tumor cells, and functions not only as a tumor-targeting ligand but also as a boron compound because it has boron in the molecule. In this study, to enhance cancer-accumulating properties of FPBA-PRX, we prepared two targeting materials; namely, (1) polyethylene glycol-modified dopamine (PEG-Dopamine), which prevents FPBA-PRX from binding to sialic acid onto normal cells under normal tissue pH conditions, and (2) a folate-modified β-cyclodextrin (FA7-β-CyD), which is selectively taken up by cells with high expression of folate receptors (FR-α). As a result, FPBA in FPBA-PRX bound to PEG-Dopamine at pH 7.4, resulting in decreased uptake by sialic acid highly expressing cells, but dissociated PEG-Dopamine at pH 6.5 in tumor microenvironment, resulting in restored cellular uptake. FA7-β-CyD interacted with adamantane present at both ends of FPBA-PRX. In addition, FPBA-PRX/FA7-β-CyD was taken up into cells more efficiently than FPBA-PRX alone in FR-α-over expressing tumor cells. These results suggest that FPBA-PRX/PEG-Dopamine and FPBA-PRX/FA7-β-CyD have potential as boron compounds by improving the tumor selectivity of FPBA-PRX.</p></div>","PeriodicalId":638,"journal":{"name":"Journal of Inclusion Phenomena and Macrocyclic Chemistry","volume":"105 9-10","pages":"569 - 577"},"PeriodicalIF":1.6,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145271555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The formation of camphor-CD inclusion complexes was confirmed through a combination of infrared spectroscopy (FTIR), X-ray diffraction (XRD), and thermogravimetric analysis (TGA).

It has been used in the production of acellular pertussis vaccine as an auxiliary material improving toxin secretion since the 1980s. 2,6-DIMEB has since gained significance in other biotechnological processes, too. Characterization of the isomeric purity and differentiation of 2,6-DIMEB from other methylated cyclodextrin types having different degree and pattern of substitution has therefore a critical relevance.

PABA drugs are used in medical and pharmaceutical fields, but their potential carcinogenicity restricts their application. SC4 was chosen as the host molecule role because of its water-soluble property, contributing to its remarkable quality as a nanosensor and drug carrier. In this work, PABA was aimed to be detected. Based on an ultraviolet–visible spectroscopy (UV–Vis) study, the SC4 and SC4-PABA liquid samples were characterised. Tauc plot was applied to determine the band gap value. Besides, density functional theory (DFT), a first principle study of the sensing of PABA by SC4 was conducted using the Quantum ESPRESSO (QE) program. The band gap, density of state (DOS), and binding energy of the optimised novel SC4-PABA host–guest complexes were calculated. By comparing the absorbance and band gap of the host molecule to those of the host–guest complex, the reactivity of the host and guest molecules was indicated by the rise in absorbance and the decrease in band gap. Absorbance obtained based on Beer–Lambert law showed the formation of SC4-PABA complexes with the direct allowed transition. Furthermore, the complexes' negative binding energy showed their stability and favourable reactions. The optimum formation of complexes by SC4 and PABA was proven at the host–guest ratio of 1:1. Applying ultrasoft pseudopotential in the band gap calculation was more precise than applying norm-conserving pseudopotential. Both the computational and experimental studies proved the detection of PABA by SC4.
