The discovery of eco-friendly, rapid, and cost-effective compounds to control diseases caused by microbes and insects are the main challenges. Herein, the magnesium oxide nanoparticles (MgO-NPs) are successfully fabricated by harnessing the metabolites secreted by Penicillium chrysogenum. The fabricated MgO-NPs were characterized using UV-Vis, XRD, TEM, DLS, EDX, FT-IR, and XPS analyses. Data showed the successful formation of crystallographic, spherical, well-dispersed MgO-NPs with sizes of 7–40 nm at a maximum wavelength of 250 nm. The EDX analysis confirms the presence of Mg and O ions as the main components with weight percentages of 13.62% and 7.76%, respectively. The activity of MgO-NPs as an antimicrobial agent was investigated against pathogens Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa, Escherichia coli, and Candida albicans, and exhibited zone of inhibitions of 12.0 ± 0.0, 12.7 ± 0.9, 23.3 ± 0.8, 17.7 ± 1.6, and 14.7 ± 0.6 mm respectively, at 200 µg mL−1. The activity is decreased by decreasing the MgO-NPs concentration. The biogenic MgO-NPs exhibit high efficacy against different larvae instar and pupa of Anopheles stephensi, with LC50 values of 12.5–15.5 ppm for I–IV larvae instar and 16.5 ppm for the pupa. Additionally, 5 mg/cm2 of MgO-NPs showed the highest protection percentages against adults of Anopheles stephensi, with values of 100% for 150 min and 67.6% ± 1.4% for 210 min.

Nephelium lappaceum L. peels was effectively used for the synthesis of magnesium oxide nanoparticles as a natural ligation agent. The XRD and SEM revealed the crystallinity and spherical morphology of the biosynthesized nanoparticles. The size of the particles was found to be 60-70 nm as deduced from XRD and SEM analysis. The particle size of as-synthesized magnesium oxide powders measured by PSA was approximately 100 nm. The successful formation of magnesium oxide nanoparticles was confirmed employing XRD, SEM-EDX and PSA analysis.

Soft Liner

Microbial growth and colonization are one of the disadvantages after the long-term use of denture soft liners. This study was aimed to evaluate the effect of the addition of magnesium oxide nanoparticles (MgONPs) on the antimicrobial activity of a denture soft liner. A total of 84 samples were prepared from a soft denture liner and divided into two groups, control group and test group to which 3% by weight of MgONPs were added, antimicrobial tests for Candida albicans, Staphylococcus aureus, and a mixture of the biofilm of both microorganisms were done, cell density count and adherence assay test was recorded before and after 6 months storage in distilled water. The results showed that the modified group performed a better antimicrobial activity compared to the control group, the addition of 3% of the nanofiller showed a significant reduction in the mean value of growth of both C. albicans, S. aureus, and the biofilm mixture (P < 0.05) before and after the storage period. In conclusion, the addition of 3% by weight of MgONPs to the denture soft liner significantly suppressed the growth of C. albicans, S. aureus up to 6 months.
