Dorna Abdolkhani Depatment of Food Sciences and Industries, Biotechnology Orientation, Islamic Azad University Yasouj Branch, Yasouj,Iran. Journal Article 2024 09 23 The investigation into the function of the smallest fullerene (C20) as a sensor and adsorbent for the detection and removal of aflatoxinM1 is a significant contribution to the field of chemical sensing and environmental remediation. The use of DFT simulations to scrutinize the interaction process between C20 and aflatoxinM1 provides valuable insights into the potential applications of fullerene in addressing aflatoxin contamination. The negative adsorption energies observed in the study indicate that the interaction between C20 and aflatoxinM1 is thermodynamically favorable, suggesting that the adsorption process is experimentally feasible. Furthermore, the calculated ∆Had and ∆Gad values demonstrate that the adsorption procedure is exothermic and spontaneous, indicating that C20 has the capability to effectively adsorb aflatoxinM1 from its surroundings. The high values of thermodynamic equilibrium constants further support the notion that the adsorption process is one-sided and non-equilibrium, emphasizing the potential for C20 to selectively capture aflatoxinM1 molecules. This selectivity is crucial in practical applications, particularly in the development of efficient adsorbents for the removal of aflatoxinM1 from contaminated environments. The analysis of frontier molecular orbital (FMO) parameters also provides valuable information regarding the electronic properties of C20 and its interaction with aflatoxinM1. The significant decline in the bandgap of C20 upon adsorption of aflatoxinM1 indicates a substantial modification in its electronic structure, which can be exploited for electrochemical detection purposes. This finding suggests that C20 has the potential to be utilized as a sensing platform for the detection of aflatoxinM1, offering a promising avenue for the development of sensitive and selective detection methods.

Box 19395-3697, Tehran, Iran Journal Article 2024 09 23 The research conducted on the applicability of fullerene (C24) as a nano-carrier, adsorbent, and sensing material for the drug delivery, removal, and detection of fosfomycin has provided valuable insights. The findings suggest that fullerene (C24) shows promise in various applications related to fosfomycin. The negative values of adsorption energies, Gibbs free energy changes, and enthalpy variations indicate that the interaction between fosfomycin and fullerene is not only possible but also spontaneous and exothermic. This suggests that C24 has the potential to be an effective adsorbent for the removal of fosfomycin from environmental samples. Furthermore, the NBO computations revealed that the existing interactions between fosfomycin and C24 have a physisorption nature. This information is crucial in understanding the mechanism of interaction between the two substances. The computed frontier molecular orbital parameters showed a significant decline in the bandgap of fullerene from 7.687 eV to 4.389 eV when fosfomycin adsorbs on its surface. This finding indicates that C24 can be utilized as an electrocatalytic modifier for the development of a novel sensor for the electrochemical detection of fosfomycin. This has significant implications for the development of new and improved methods for detecting this antibiotic. This suggests that C24 can serve as an appropriate carrier for the targeted delivery of fosfomycin. This finding opens up possibilities for the development of targeted drug delivery systems using C24 as a carrier.

Tehran, Iran Journal Article 2024 10 07 The electrochemical sensing properties of the synthesized chromenes under ZIF-8 catalyst conditions for K⁺ detection were investigated using infrared (IR) spectroscopy and frontier molecular orbital (FMO) theory. The results revealed that the synthesized derivative with o-NO2 substitution exhibited the strongest interaction with K⁺, with a Kf value of 5.199×10+24. In addition, the reducing of chemical hardness in the formation of complexes from K+ and the all of chromene synthesized derivatives, which characterizes their softness and reactivity, shows that electron transfer takes place in the formation of these complexes than the pure cation without chromene-based ligands. Also as evident from the presented results, K+ demonstrates a high propensity for electron absorption due to its elevated electrophilicity and maximum charge capacity values compared to the investigated chromene derivatives exhibit low values for both indices, indicating a preference for electron donation. These findings suggest that it could serve as a selective and sensitive recognition element for the development of a new electrochemical sensor for detecting K⁺.

Journal Article 2024 11 24 In recent years, increasing the shelf life and preventing the spoilage of highly perishable food products such as fish has become a significant challenge for scientists and professionals in the health industry. These products not only pose health risks to the general public due to the transmission of pathogens to consumers and the creation of health hazards, but they also have economic importance. Materials and Methods: This research aimed to prepare probiotic films from sodium caseinate-gelatin containing Lactobacillus paracasei, Bifidobacterium bifidum, and Lactobacillus plantarum, and to evaluate their application in the microbial and mechanical properties of salmon fillets during 12 days of refrigerated storage. The physical and mechanical properties of the designed films were assessed. Additionally, the salmon fillets were examined for microbial parameters. Results: Based on the findings, a negative correlation was observed between the survival of probiotic bacteria and the storage time of the films. The number of Lactobacillus paracasei, Bifidobacterium bifidum, and Lactobacillus plantarum bacteria started from day 0 with values of (2.9, 3.9, and 1.9 log cells) respectively, and reached (6.79, 5.84, and 6.14 log cells) by the end of the study (day 12). In other results, it was observed that sodium caseinate-gelatin probiotic films delayed microbial growth in salmon fillets compared to the control group. Conclusion: Overall, sodium caseinate-gelatin probiotic films significantly increased the shelf life of salmon fillets and can be considered as innovative packaging materials with potential applications in various industries, especially the food industry.
