“…This property is due to the extremely small size and surface-tovolume ratio of these particles. 26 Therefore, due to the high antibacterial activity of the NPs, they can be used to enhance the safety of food packaging 27,28 as well as in the development of a new generation of antibacterial drugs. 29,30 In this area, cobalt oxide (Co 3 O 4 ) NPs have shown outstanding features because of their promising physicochemical properties like the anisotropy constant, coercivity and Curie temperature, saturation magnetization and ease of fabrication.…”

The interaction of NPs with biological systems may reveal useful details about their pharmacodynamic, anticancer and antibacterial effects. Methods: Herein, the interaction of as-synthesized Co 3 O 4 NPs with HSA was explored by different kinds of fluorescence and CD spectroscopic methods, as well as molecular docking studies. Also, the anticancer effect of Co 3 O 4 NPs against leukemia K562 cells was investigated by MTT, LDH, caspase, real-time PCR, ROS, cell cycle, and apoptosis assays. Afterwards, the antibacterial effects of Co 3 O 4 NPs against three pathogenic bacteria were disclosed by antibacterial assays. Results: Different characterization methods such as TEM, DLS, zeta potential and XRD studies proved that fabricated Co 3 O 4 NPs by sol-gel method have a diameter of around 50 nm, hydrodynamic radius of 177 nm with a charge distribution of −33.04 mV and a welldefined crystalline phase. Intrinsic, extrinsic, and synchronous fluorescence as well as CD studies, respectively, showed that the HSA undergoes some fluorescence quenching, minor conformational changes, microenvironmental changes as well as no structural changes in the secondary structure, after interaction with Co 3 O 4 NPs. Molecular docking results also verified that the spherical clusters with a dimension of 1.5 nm exhibit the most binding energy with HSA molecules. Anticancer assays demonstrated that Co 3 O 4 NPs can selectively lead to the reduction of K562 cell viability through the cell membrane damage, activation of caspase-9,-8 and-3, elevation of Bax/Bcl-2 mRNA ratio, ROS production, cell cycle arrest, and apoptosis. Finally, antibacterial assays disclosed that Co 3 O 4 NPs can stimulate a promising antibacterial effect against pathogenic bacteria. Conclusion: In general, these observations can provide useful information for the early stages of nanomaterial applications in therapeutic platforms.

The development of antimicrobial food packaging is needed for food preservation and quality maintenance. Silver nanoparticles (AgNPs) have been widely used as an antimicrobial agent in food packaging technologies. However, the risks associated with their potential migration into foods are a major concern. This paper comprehensively reviews the use of AgNPs in food packaging technologies. The application of AgNPs in food packaging technologies has been regulated by the United States Food and Drug Administration and the European Food Safety Authority. The addition of AgNPs into food packaging can improve their barrier, mechanical, and antibacterial properties, as well as maintain the quality of foods. Migration of AgNPs from food packaging into foods is still a concern as it has implications for human health associated with their toxicity properties. A study on the toxicological properties of AgNPs released from food packaging needs to be carried out intensively to ensure their safety before being widely implemented. Moreover, comprehensive economic evaluation to implement AgNPs in food packaging is needed as such a study is missing in the literature.

Biological fouling has caused a lot of concern in marine industries due to the attachment of microorganisms including bacteria, algae, and diatoms on a marine surface to create a biofilm. Biofouling causes negative impacts on the marine industry such as an increase in weights of hulls, low speed, and high fuel consumption. In the recent past, nanoparticles have attracted a lot of attention in the fields of material science, chemistry, and biology owing to their rare biological properties. Silver nanoparticles (AgNPs) have been long known for its strong toxicity against a wide range of microorganisms. Herein, we synthesized the AgNPs via a green synthesis approach known for its benefits such as one-pot, inexpensive, and eco-friendly; by using Illicium verum (IV) extract as a demoting and sustaining agent. Further, characterization tests of obtained AgNPs-IV were investigated including Ultraviolet-visible spectroscopy (UV-Vis), Fourier-transform infrared spectroscopy (FTIR), X-Ray Diffraction (XRD), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM) and Atomic force microscopy (AFM). The UV-Vis result confirmed the AgNPs-IV formation with its surface Plasmon resonance peak. FTIR was tested to investigate the bio-functional groups liable for the AgNPs-IV synthesis. XRD peaks also meet with the standard of AgNPs (JCPDS: 41-1402). SEM, TEM, and AFM analysis of AgNPs-IV showed the hexagonal structure with 14.56 nm mean size. The cell growth of diatom on 5 th day with blank sample suspension was 2.308 (Cell 10 5 number/mL), while for AgNPs-IV sample suspension was 0.19 (Cell 10 5 number/mL). The green synthesized AgNPs-IV showed excellent antidiatom activity against Paeodactylum Tricornutum (P. Tricornutum) marine diatom.
