[PMID: 38668165 PMCID: PMC11053935 DOI: 10.3390/nano14080670] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/27/2024] [Revised: 04/07/2024] [Accepted: 04/10/2024] [Indexed: 04/29/2024]
Abstract
Tellurium (Te) is the heaviest stable chalcogen and is a rare element in Earth's crust (one to five ppb). It was discovered in gold ore from mines in Kleinschlatten near the present-day city of Zlatna, Romania. Industrial and other applications of Te focus on its inorganic forms. Tellurium can be toxic to animals and humans at low doses. Chronic tellurium poisoning endangers the kidney, liver, and nervous system. However, Te can be effective against bacteria and is able to destroy cancer cells. Tellurium can also be used to develop redox modulators and enzyme inhibitors. Soluble salts that contain Te had a role as therapeutic and antimicrobial agents before the advent of antibiotics. The pharmaceutical use of Te is not widespread due to the narrow margin between beneficial and toxic doses, but there are differences between the measure of toxicity based on the Te form. Nano-tellurium (Te-NPs) has several applications: it can act as an adsorptive agent to remove pollutants, and it can be used in antibacterial coating, photo-catalysis for the degradation of dyes, and conductive electronic materials. Nano-sized Te particles are the most promising and can be produced in both chemical and biological ways. Safety assessments are essential to determine the potential risks and benefits of using Te compounds in various applications. Future challenges and directions in developing nano-materials, nano-alloys, and nano-structures based on Te are still open to debate.

NANOMATERIALS (BASEL, SWITZERLAND) 2024; 14:292. [PMID: 38334563 PMCID: PMC10856574 DOI: 10.3390/nano14030292] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 01/25/2024] [Accepted: 01/27/2024] [Indexed: 02/10/2024]
Abstract
Banana (Musa acuminate) has been popular among consumers worldwide due to its rich nutrients and minerals. However, bananas are highly susceptible to the physical and biological factors that lead to postharvest loss during transportation and storage. In this work, novel sodium alginate (SA) films incorporated with silver nitroprusside nanoparticles (AgNNPs) were prepared to extend the shelf life of bananas through antibacterial and antioxidant coating. The results exhibited that AgNNPs were cubical and that their size was <500 nm, with metal composition being Ag and Fe. Additionally, the incorporation of AgNNPs in the SA film was seen in FE-SEM and zeta analysis, with an average size of about 365.6 nm. Furthermore, the functional and crystalline properties of AgNNPs were assessed through FTIR and XRD. Transmittance testing of the SA-AgNNPs films confirmed they have good UV barrier properties. SA-AgNNPs films exhibited excellent high antibacterial activity against foodborne pathogens including L. monocytogenes, S. enterica, and E. coli at the concentration of 500 µg/mL. Moreover, during the storage of bananas, SA-AgNNPs nanocomposite coatings act as a barrier to microbial contamination and slow down the ripening of bananas. As a result, compared with SA-coated and uncoated bananas, SA-AgNNPs-coated bananas exhibited the lowest weight loss and lowest total bacterial colonies, thus greatly extending their shelf life. Particularly when coated with SA-AgNNPs films, total bacterial colonies (TBC) in the banana peel and pulp were as low as 1.13 × 103 and 51 CUF/g on the ninth day of storage, respectively. Our work offers an efficient strategy to improve the quality of bananas during the postharvest period, with extensive applications in fruit preservation and food packing.

Abstract
Bacterial infections can lead to the formation of chronic wounds and delay the wound-healing process. Therefore, it is important to explore safe and efficient antimicrobial agents that have wound-healing and biocompatible properties. In this study, novel starch-fabricated silver nitroprusside nanoparticles (S-AgNP NPs) were prepared for biocompatible wound-healing applications. The study showed that S-AgNP NPs are spherical, with an average size of 356 ± 22.28 d. nm and zeta potential of -27.8 ± 2.80 mV, respectively. Furthermore, the FTIR and XRD results showed that S-AgNP NPs have functional groups and crystal structures from the silver nitroprusside nanoparticles (AgNP NPs) and starch. Additionally, S-AgNP NPs showed excellent bacterial and biofilm inhibition on B. cereus (15.6 μg/mL), L. monocytogenes (15.6 μg/mL), S. aureus (31.3 μg/mL), E. coli (31.3 μg/mL) and S. enterica (62.5 μg/mL). Moreover, S-AgNP NPs promoted cell migration and proliferation at a concentration of 62.5 μg/mL compared to AgNP NPs. Meanwhile, S-AgNP NPs had good biocompatibility and low cytotoxicity compared to AgNP NPs. Therefore, this study provided new ideas for the development of wound-healing agents with bacteriostatic properties in chronic wounds.
