    A Novel Phenalenone-Based Probe for Dual-Mode Hydrazine Detection
    (Elsevier Inc., 2025) Saygili, Ecem; Kibris, Erman; Gelen, Sultan Sacide; Eldem, Asli; Odaci, Dilek; Ucuncu, Muhammed
    Despite its toxic and carcinogenic nature, hydrazine (N2H4) remains a crucial compound in environmental and industrial applications. Its associated risks demand effective monitoring; however, conventional detection methods often fall short in sensitivity and accuracy, highlighting the need for innovative approaches. This study presents a novel turn-on probe based on phenalenone-phthalimide scaffold, 2-(1-oxo-1H-phenalen-6-yl)isoindoline-1,3-dione (6-AP-PI), specifically designed for N2H4 detection, offering a novel approach by combining fluorescence and electrochemical signals, thereby significantly enhancing detection performance. 6-AP-PI exhibits an exceptional selectivity and sensitivity toward N2H4 both in solution and cellular media, providing rapid signal enhancement (<1 min) and a low limit of detection (490 nM). Overall, this dual-mode design effectively addresses the limitations of traditional methods, enhancing both sensitivity and selectivity, positioning the 6-AP-PI probe as a promising tool for future health, safety, and environmental protection applications.

    Nitrate Sensing With Molecular Cage Ionophores: a Potentiometric Approach
    (Royal Soc Chemistry, 2025) Onder, Ahmet; Begar, Ferit; Kibris, Erman; Buyukcakir, Onur; Yildiz, Umit Hakan
    Nitrate ions are widespread environmental pollutants in water and soil, posing critical risks to both human health and ecosystems. This study introduces a molecular cage as a novel ionophore for potentiometric nitrate-selective ion-selective electrodes (ISEs) designed for enhanced specificity and sensitivity. Among six synthetic candidates, the electrode incorporating a 1,3,5-tri(p-hydroxyphenyl)benzene-based chlorotriazine pillared cage molecule (CAGE-1) exhibited superior performance, characterized by a linear response in the nitrate concentration range of 1.0 x 10-5 to 1.0 x 10-1 M, with a high coefficient of determination (R2 = 0.9971) and a slope of -53.1 +/- 1.4 mV dec-1. The electrode also achieved a limit of detection of 7.5 x 10-6 M. These findings highlight the potential of molecular cages as ionophores for nitrate sensing in environmental applications.

    A Selective Bodipy-Based Fluorescent Sensor for the Detection of Cu2+ Ions in Biological and Environmental Samples
    (Pergamon-elsevier Science Ltd, 2025) Eldem, Asli; Kibris, Erman; Ucuncu, Muhammed
    In this study, we present the design, synthesis, and characterization of a 'turn-on' fluorescent probe, BOD-HDZ, for the selective detection of Cu2+ ions in semi-aqueous solutions, environmental samples (water and soil), and MCF-7 cancer cells. BOD-HDZ was synthesized by functionalizing meso-formyl-BODIPY (BOD-ALD) with a 2-hydrazinopyridine, resulting in fluorescence quenching via a photoinduced electron transfer (PET) mechanism. The 1:1 coordination between Cu2+ and the probe was confirmed through Job's plot analysis and 1H NMR spectroscopy, leading to a 210-fold fluorescence enhancement at 515 nm. BOD-HDZ demonstrated exceptional sensing properties, including a rapid response time (<1 min), a broad operational pH range (2-12), and high sensitivity with a detection limit of 141 nM.
