The scavenging activity of myoglobin toward peroxynitrite (PON) was studied in meat extracts, using a new developed electrochemical method (based on cobalt phthalocyanine-modified screen-printed carbon electrode, SPCE/CoPc) and calculating kinetic parameters of PON decay (such as half-time and apparent rate constants). As reactive oxygen/nitrogen species (ROS/RNS) affect the food quality, the consumers can be negatively influenced. The discoloration, rancidity, and flavor of meat are altered in the presence of these species, such as PON. Our new highly thermically stable, cost-effective, rapid, and simple electrocatalytical method was combined with a flow injection analysis system to achieve high sensitivity (10.843 nA µM−1) at a nanomolar level LoD (400 nM), within a linear range of 3–180 µM. The proposed biosensor was fully characterized using SEM, FTIR, Raman spectroscopy, Cyclic Voltammetry (CV), Differential Pulse Voltammetry (DPV), and Linear Sweep Voltammetry (LSV). These achievements were obtained due to the CoPc-mediated reduction of PON at very low potentials (around 0.1 V vs. Ag/AgCl pseudoreference). We also proposed a redox mechanism involving two electrons in the reduction of peroxynitrite to nitrite and studied some important interfering species (nitrite, nitrate, hydrogen peroxide, dopamine, ascorbic acid), which showed that our method is highly selective. These features make our work relevant, as it could be further applied to study the kinetics of important oxidative processes in vivo or in vitro, as PON is usually present in the nanomolar or micromolar range in physiological conditions, and our method is sensitive enough to be applied.

In this paper, chitin (Ch) was extracted by an optimized method from cuttlebone of the Persian Gulf cuttlefish (Sepiidae, Cephalopoda). The extracted chitin was characterized by Fourier-transform infrared spectroscopy (FT-IR), X-ray powder diffraction (XRD) and thermal gravimetric analysis (TGA) which showed that the extracted chitin was in alpha form. The degree of N-acetylation (DA) and degree of substitution (DS) of α-chitin were calculated using titration method and FTIR spectroscopy and found to be 80–82% and 19.57 respectively. The α-Chitin was used as biomolecules for the preparation of nanostructured Ch/ZnO via a hydrothermal method. The obtained nanocomposite was characterized using FT-IR, XRD, scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX) analysis. The antimicrobial aspect of Ch/ZnO nanocomposite was previously proposed. In this paper, attempt was made to add the catalytic feature to these traits. For this purpose, the nanostructured Ch/ZnO was used as reusable nanocatalyst in the green and efficient synthesis of Benzo[a]pyrano(2,3-c)phenazine derivatives thru a four components microwave aided domino reaction. Eco-friendly, easy work up and separation of the nanostructured catalyst are some of the highlighted features this protocol.

Reactive oxygen/nitrogen species (ROS/RNS) have a great impact on cellular response to stress, cell proliferation, cell death, cancer, aging, or male infertility. Additionally, in the food industry and for consumers as well, it is very important to monitor quality and freshness of raw meat. Different factors are a sign of meat alteration (e.g., discoloration, rancidity, alteration of flavor). One pathway of alteration is the scavenging activity of myoglobin towards RNS (such as peroxynitrite, PON). This paper presents the development of an electrochemical PON sensor using cobalt phthalocyanine (CoPc) as a simple, cost effective, highly thermally stable, biomimetic catalyst, and the application of this electrochemical screen-printed carbon electrode (SPCE)-based sensor to meat extract samples, using flow injection analysis (FIA). The reduction of peroxynitrite, mediated by CoPc, occurs at a very low potential (around 0.1 V vs. Ag/AgCl pseudoreference); as for higher potentials, the mechanism of mediation changes, and the electro-oxidation of PON is observed. The surface of the modified electrode was characterized using SEM, FTIR and Cyclic Voltametry. The interaction of PON with myoglobin was studied using both UV-Vis and chronoamperometry (at 0.1 V, using the FIA system). The calibration of the electrode was performed: Ired (nA) = 6.313·CPON (µM) + 17.469; (R² = 0.9938). The calculated LOD was equal to 2.37 µM and the linear range was 3–180 µM. The performance of the electrode can be further improved using a pre-treatment (electro-reduction of the CoPc deposited film, at −0.3 V, during 60s). This could help us monitor and quantify how much PON was decomposed and when meat extracts are spiked with different PON concentrations, in a highly selective, sensitive, and reproducible way.
