“…This is due to the well-documented diverse biological activity of this most expensive bee product. In particular, evidence has been obtained of its antimicrobial action against both bacteria (including antibiotic-resistant strains) and pathogenic fungi [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ]. The therapeutic effect of the external use of apitoxin in the treatment of wounds [ 24 , 25 ] as well as skin diseases [ 26 ] is largely associated with antimicrobial activity.…”

Due to its great medical and pharmaceutical importance, honey bee venom is considered to be well characterized both chemically and in terms of biomedical activity. However, this study shows that our knowledge of the composition and antimicrobial properties of Apis mellifera venom is incomplete. In this work, the composition of volatile and extractive components of dry and fresh bee venom (BV) was determined by GC-MS, as well as antimicrobial activity against seven types of pathogenic microorganisms. One-hundred and forty-nine organic C1–C19 compounds of different classes were found in the volatile secretions of the studied BV samples. One-hundred and fifty-two organic C2–C36 compounds were registered in ether extracts, and 201 compounds were identified in methanol extracts. More than half of these compounds are new to BV. In microbiological tests involving four species of pathogenic Gram-positive and two species of Gram-negative bacteria, as well as one species of pathogenic fungi, the values of the minimum inhibitory concentration (MIC) and minimum bactericidal/fungicidal concentration (MBC/MFC) were determined for samples of dry BV, as well as ether and methanol extracts from it. Gram-positive bacteria show the greatest sensitivity to the action of all tested drugs. The minimum MIC values for Gram-positive bacteria in the range of 0.12–7.63 ng mL−1 were recorded for whole BV, while for the methanol extract they were 0.49–125 ng mL−1. The ether extracts had a weaker effect on the tested bacteria (MIC values 31.25–500 ng mL−1). Interestingly, Escherichia coli was more sensitive (MIC 7.63–500 ng mL−1) to the action of bee venom compared to Pseudomonas aeruginosa (MIC ≥ 500 ng mL−1). The results of the tests carried out indicate that the antimicrobial effect of BV is associated with the presence of not only peptides, such as melittin, but also low molecular weight metabolites.

“…Both BV as a whole and its individual components demonstrate anti-cancer activity [ 10 , 13 , 23 , 27 , 28 , 29 , 30 , 31 , 32 , 33 ]. Cancer diseases are the main cause of death in the population, and many of their forms are characterized by high malignancy, metastasis, and resistance to chemotherapy [ 34 ].…”

“…As drug resistance spreads worldwide, antibiotics are becoming less effective, leading to increased challenges in treating infections and higher mortality rates. Urgent development of new antimicrobial agents is necessary to combat resistant Gram-negative bacterial infections [1][2][3][4]. Over the past decade, nanotechnology has made significant advancements and is undergoing rapid development as a multidisciplinary scientific field.…”

Antibiotic resistance has substantially risen worldwide. Considering this worrying condition, many studies on biogenic nanoparticles and their antimicrobial and anticancer properties have been conducted. There are numerous ways to improve stability and dispersion through conjugate peroration with bioactive natural ingredients such as chitosan. Here, a fungal isolate was isolated and identified as Talaromyces sp. 7S1 by 18SrRNA with accession no. OP295112. This strain prepared biogenic silver nanoparticles (AgNPs) and chitosan-AgNPs conjugate (Ch-AgNPs). Various imaging and analytical methods including UV-vis, XRD, FTIR-spectroscopy, TEM, and SEM were utilized to characterize biogenic nanoparticles and conjugates. The biosynthesized AgNPs along with the prepared conjugate were evaluated for their antimicrobial effects on Gram-positive (Staphylococcus aureus (RCMB 010028) and Bacillus subtilis (RCMB 010067)) and Gram-negative (Escherichia coli )RCMB 010052) and Salmonella typhi)RCMB 010052)) pathogens. Ch-AgNPs showed good antimicrobial activity compared to control. Results revealed that the crude extract showed antibacterial activity against E. coli and S. aureus while a substantial effect was observed with AgNPs. AgNPs displayed potent antibacterial activity against E. coli, S. aureus, and B. subtilis, while they showed moderate activity against S. typhi. Furthermore, Ch-AgNPs exhibited a pronounced antibacterial activity against E. coli, and S. aureus and low antibacterial activity against S. typhi. On the other hand, the obtained AgNPs and Ch-AgNPs exhibited a pronounced antibiofilm activity against all tested strains. Additionally, the antioxidant and anticancer activities of AgNPs and Ch-AgNPs were also evaluated. Collectively, AgNPs and Ch-AgNPs exhibit good antimicrobial activity, nevertheless, Ch-AgNPs conjugate reduced the toxicity of AgNPs which may represent a safer tool to inhibit bacterial pathogens.

In the current report, we have successfully synthesized nanocomposites of PMMA incorporating different doping of CeO2 through a chemical approach. XRD results reflects decent matching for CeO2 nanoparticles with 29 nm crystallite size. FTIR spectroscopy demonstrates the characteristic functional groups validating the successful formation of the composite. The optical study of PMMA and the nanocomposites has proven that the optical properties such as band gap, refractive index, optical permittivity, and loss tangent factor are affected by adding CeO2 to the PMMA matrix.The peak residing around 420 nm by UV measurements is allocated to occurring electrons photoexcitation from the valence to conduction band inherent in CeO2. The dielectric measurements were achieved using broadband dielectric spectroscopy upon a wide span of frequencies (10–1–107 Hz) and within temperatures from − 10 to 80 °C with a step of 10 °C. The permittivity decreases by adding CeO2 and the dielectric parameters are thermally enhanced, however, the temperature influence is based on CeO2 content, the higher the CeO2 amount, the higher the influence of temperature. The results of the nanocomposites revealed antibacterial activity counter to gram-positive bacteria strain (S. aureus, and B. subtilis), and gram-negative bacteria (E. coli, and K. pneumoniae), yeast (C. albicans, as well as fungi (A. niger). Inherently, the change in CeO2 concentration from 0.01 to 0.1 wt% delivers maximum influence against gram-negative bacteria. These PMMA CeO2-doped composites are beneficial for optoelectronic areas and devices.
