    Confinement Effects on Chemical Equilibria: Pentacyano(Pyrazine)Ferrate(II) Stability Changes within Nanosized Droplets of Water by Teofilo Borunda, Alexander J. Myers, J. Mary Fisher, Debbie C. Crans, Michael D. Johnson

    Published 2018-04-01
    “…Nanoscale confinement is known to impact properties of molecules and we observed changes in the reactivity of an iron coordination complex, pentacyano(pyrazine)ferrate(II). The confinement of two coordination complexes in a sodium AOT/isooctane reverse micellar (RM) water droplet was found to dramatically increase the hydrolysis rate of [Fe(CN)5pyz]3− and change the monomer-dimer equilibria between [Fe(CN)5pyz]3− and [Fe2(CN)10pyz]6−. …”

    Heme Degradation in Pathophysiology of and Countermeasures to Inflammation-Associated Disease by Donald David Haines, Arpad Tosaki

    Published 2020-12-01
    “…The class of tetrapyrrol “coordination complexes” called hemes are prosthetic group components of metalloproteins including hemoglobin, which provide functionality to these physiologically essential macromolecules by reversibly binding diatomic gasses, notably O<sub>2</sub>, which complexes to ferrous (reduced/Fe(II)) iron within the heme porphyrin ring of hemoglobin in a pH- and PCO<sub>2</sub>-dependent manner—thus allowing their transport and delivery to anatomic sites of their function. …”

    “Turn-On” Fluorescent Assay of Biothiols Based on Nitrogen-Rich Polymer Carbon Nanostrips and Its Application in Cell Imaging by Xiangying Meng, Jinjuan Qiao, Ronglan Zhao, Hairong Chu, Ying Wang, Xiangyu Chen, Zhengjun Yi

    Published 2019-01-01
    “…Ag+ ion can induce the fluorescence quenching of NRPCNSs due to the formation of nonfluorescent coordination complexes via robust Ag-N interaction. Once addition of biothiols, such as cysteine (Cys) and glutathione (GSH), Ag+ ions prefer to interact with biothiols rather than NRPCNSs, which could be attribute to the formation of Ag-S bond, thus leading to effective fluorescent recovery of NRPCNSs. …”
