In the colorimetric studies, PPSD in methanol medium responded as probe to detect cations iron (Fe²⁺) and zinc (Zn²⁺). During attempts to venture PPSD as probe with series of cations (Fe²⁺, Co²⁺, Ni²⁺, Ca²⁺, Li⁺, Zn²⁺, Cu²⁺, Na⁺, Al³⁺, and Ce²⁺), detection of cations was observed specifically with Zn²⁺ and Fe²⁺ cations. Herein, the colorless probe medium was identified to turn into dark blue with Fe²⁺ cations, whereas Zn²⁺ cations showed fluorescent green under UV light. To validate these colorimetric detections, Fe²⁺ cations were studied by UV-vis and Zn²⁺ cations by photoluminescence. To validate the colorimetric detection of Fe²⁺ and Zn²⁺ cations, UV-vis absorbance analysis was performed for Fe²⁺ cations while Zn²⁺ cations found to be supported by photoluminescence data. Based on absorbance and fluorescence titration studies, the detection limits (limit of detection [LOD]) for Fe²⁺ (9.7789 × 10⁻⁵ M) and Zn²⁺ (9.6340 × 10⁻⁵ M) cations were established, respectively. The binding constants for Fe²⁺ and Zn²⁺ cations were determined to be 7.92 × 10⁴ M⁻¹ and 2.76 × 10⁸ M⁻¹, from the Benesi–Hildebrand (B-H) equation. Consequently, PPSD showed a photoluminescence quantum yield (ɸ = 0.038), which increased approximately 11-fold (ɸ = 0.417) due to its interaction with Zn²⁺ cations. FTIR, multinuclear NMR (¹H, ¹³C, and ³¹P), photoluminescence, UV-vis, NMR titration, HRSEM, EDS, cyclic voltammetry, and DFT studies were used to characterize structures, sensing abilities and binding studies of PPSD with Fe²⁺/Zn²⁺ cations.</p>\u0000 </div>","PeriodicalId":8344,"journal":{"name":"Applied Organometallic Chemistry","volume":"39 4","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143533331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study assessed the anticancer activity of chitosan (CS)-coated gold nanoparticles (AuNPs) and a combination of AuNPs–papain (Pap)–folic acid (FA) nanomaterial platforms against Michigan Cancer Foundation-7 (MCF-7) cancer cell lines. A range of methods, including ultraviolet–visible (UV–Vis), Fourier transform infrared (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDS), and zeta potential, were used to characterize the prepared nanomaterials. AuNPs and AuNPs–Pap–FA exhibited UV–Vis absorption at 525 and 558 nm, respectively. In the XRD test, the AuNPs peaks were found at 32°, 39°, 45°, 65°, and 78.5°, and the AuNPs–CS–Pap–FA peaks were identified at 29, 37°, 45°, 65°, and 78.5°. SEM revealed irregularly dispensed oval shapes of AuNPs. TEM images confirmed the shape of the AuNPs before and after the coating with Pap and FA. The mean diameter of the AuNPs was 15 nm, and for the AuNPs–CS–Pap–FA, it was 22.5 nm.

The widespread use of this medication has led to its accumulation in aquatic and sewage environments. Even in small quantities, this drug poses risks to both humans and other animals, particularly in aquatic environments. In this study, alkyl and sulfonic groups were linked to a metal–organic framework (MOF) for Zr-MOF-NH-(CH₂)₃-SO₃H synthesis using a post-synthetic method. Subsequently, the performance of Zr-MOF-NH-(CH₂)₃-SO₃H as a nano-adsorbent for the removal of metformin pharmaceutical pollutants was investigated. Under optimal conditions (pH = 9, contact time 90 min, adsorbent dose = 0.1 g/L, and metformin concentration 25 ppm), the maximum adsorption capacity for removal was approximately 160 mg/g. The interactions between the framework and metformin, the effect of pH on these interactions, and the possible mechanisms were investigated. The final results showed that the Zr-MOF-NH-(CH₂)₃-SO₃H framework has a high adsorption capacity to remove the metformin drug, and this high adsorption probably occurs mostly via electrostatic attraction, which results in more interactions, such as H-bonding, π-π, and acid and base interactions. Additionally, the freely rotating alkyl chains (−(CH₂)₃SO₃H) in the MOF can further enhance the material's ability to capture metformin by improving the penetration of metformin into the framework, thus significantly enhancing the adsorption performance.
