Article Synopsis
  • - This study introduces a new treatment for vaginal infections caused by Candidiasis using a silver secnidazole nano-hybrid emulsion (Ag-Secn-NHE) combined with probiotics, showing better antifungal properties compared to traditional treatments.
  • - Researchers found that Ag-Secn-NHE-based probiotics, particularly when mixed with Saccharomyces cerevisiae, demonstrated significant antifungal effects against resistant strains like Candida auris and Cryptococcus neoformans, achieving lower minimum inhibitory concentrations (MIC) than free Ag-Secn-NHE.
  • - The study also revealed that Ag-Secn-NHE-based probiotics effectively inhibit biofilm formation (75% against C. auris) and cause noticeable cellular damage to the fungi, confirming their

Dermatophytosis is a critical sort of skin infection caused by dermatophytes. The long-term treatment of such skin infections may be improved through the application of nanotechnology. This study aimed to prepare griseofulvin zinc Nanohybrid emulsion (GF-Zn-NHE) to improve griseofulvin activity against dermatophytes and some opportunistic pathogenic yeasts and bacteria.

The agricultural use of silica (SiO) nanoparticles (NPs) has the potential to control insect pests while the safety and tritrophic effects on plants and beneficial natural enemies remains unknown. Here, we evaluate the effects of silica NPs on insect pests with different feeding niches, natural enemies, and a plant. Silica NPs were applied at different concentrations (75-425 mg/L) on field-cultivated faba bean and soybean for two growing seasons.

The present study investigated the biosynthesis of silver (AgNPs), zinc oxide (ZnONPs) and titanium dioxide (TiONPs) nanoparticles using , and . Nanocomposites (NCs) were successfully synthesized by mixing nanoparticles using a Sonic Vibra-Cell VC/VCX processor. A number of analytical techniques were used to characterize the synthesized biological metal nanoparticles.
