“…From a biological point of view, the nitrogen oxide donors, particularly the S-nitrosothiols, are more interesting for the regulation of nitric oxide-dependent physiological processes. The present work shows that the mechanism of NO donation by SNAP to iron-porphyrins is different from the binding of NO molecules dissolved in buffer [26][27][28], leading to a much faster and probably direct reductive nitrosylation. It is also shown that simple membrane models, such as micelles, can influence the equilibrium between porphyrin monomers and dimers and modify nitrosylation rates.…”

“…This interaction is expected to influence axial ligation. Several studies of nitric oxide reactions with water soluble ironporphyrins have recently appeared using solutions equilibrated with NO gas under various partial pressures [15,17,26,28]. From a biological point of view, the nitrogen oxide donors, particularly the S-nitrosothiols, are more interesting for the regulation of nitric oxide-dependent physiological processes.…”

“…This is also observed in the presence of SDS micelles, but no spectral modifications occur in the presence of CTAB or C 12 E 9 . These spectral changes are due to the nitrosylation of the iron-porphyrin and is characteristic of NO-Fe(II)porphyrin [26,27].…”

“…Nitric oxide is known to react with Fe(III)-and Fe(II)-porphyrins to produce the corresponding adducts. NO-Fe(III)P can further react with NO to generate the reduced species NO-Fe(II)P after an autoreduction process characterized by a solvent attack (H 2 O, OH À , -OH) on the ferrous nitrosonium complex (Fe 2þ -NO þ ) formed after NO binding to the ferric iron [6,26]. The reductive formation of NO-Fe(II)porphyrin is then thought to occur as:…”

Catalytic nanoparticles (CNPs) as heterogeneous catalyst reveals superior activity due to their physio‐chemical features, such as high surface‐to‐volume ratio and unique optical, electric, and magnetic properties. The CNPs, based on their physio‐chemical nature, can either increase the reactive oxygen species (ROS) level for tumor and antibacterial therapy or eliminate the ROS for cytoprotection, anti‐inflammation, and anti‐aging. In addition, the catalytic activity of nanozymes could specifically trigger a specific reaction accompanied by the optical feature change, presenting the feasibility of biosensor and bioimaging applications. Undoubtedly, CNPs play a pivotal role in pushing the evolution of technologies in medical and clinical fields, and advanced strategies and nanomaterials rely on the input of chemical experts to develop. Herein, we present a systematic and comprehensive review of the challenges and recent development of catalytic NPs for biomedical applications from the viewpoint of advanced nanomaterial with unique catalytic activity and additional functions. Furthermore, we critically discuss the biosafety issue of applying biodegradable and non‐biodegradable nanozymes and future perspectives to guide a promising direction in developing span‐new nanozymes and more intelligent strategies for overcoming the current clinical limitations.This article is protected by copyright.

Photometric Detection of Nitric Oxide Using a Dissolved Iron(III) Corrole as a Sensitizer

The potential of an iron(III) corrole complex for use in the detection of nitric oxide (NO) was investigated. The reversible conversion of an dissolved iron(III) corrole to its corresponding nitrosyl complex using gaseous nitric oxide was monitored by UV/Vis spectroscopy. The spectral differences between both coordination compounds were used to determine photometrically small amounts of nitric oxide in the sub‐parts‐per‐million range. The spectral changes due to NO binding were assigned to charge‐transfer transitions arising upon NO coordination and were analyzed in detail with support from quantum chemical calculations. Finally, films of the iron(III) corrole were deposited on quartz glass. Thus, the great potential of iron(III) corroles for the development of advanced, highly sensitive and low‐energy‐consuming photonic sensing devices was demonstrated.
