This study reports preparation and physicochemical characterization of natural antimicrobials (Origanum Syriacum essential oil (OSEO), shrimp chitosan nanoparticles (CSNPs)) and new imidazolium ionic liquid-supported Zn(II)Salen. These antimicrobials were separately or co-encapsulated by CSNPs to fabricate novel antimicrobial nanoplatforms "NPFs" (OSEO-loaded CSNPs (NPF-1), Zn(II)Salen-loaded CSNPs (NPF-2), and Zn(II)Salen@OSEO-loaded CSNPs (NPF-3)). The finding of loading, encapsulation, and antimicrobial release studies confirm the suitability of CSNPs for nanoencapsulation of Zn(II)Salen and OSEO. All NPFs can significantly suppress the growth of microbial species with performances dependent upon the microbial strain and nanoplatform concentration. The susceptibility of microbes toward new antimicrobials was as follows; Gram-positive bacteria > Gram-negative bacteria > fungi. The amazing physicochemical features of new nanoplatforms and their bioactive ingredients (Zn(II)Salen, OSEO, and CSNPs) signify the importance of our designs for developing a new generation of nanopharmaceuticals supported both natural products and biogenic ionic metal cofactors, targeting the multidrug resistant (MDR) pathogens.

Article Synopsis
- The study evaluated the antibacterial and antifungal properties of certain extracts and their essential oils by isolating bacteria from urine and fungi from spoiled food.
- Results showed that while the extracts had some inhibitory effects on bacteria and fungi, their essential oils were more effective in killing them, indicating greater antimicrobial potential.
- Additionally, specific extracts demonstrated mild antibiofilm activity, and one extract was found to preserve grapes for about 40 days, suggesting possible applications in food preservation.

Essential oils (EOs) with established and well-known activities against human pathogens might become new therapeutics in multidrug-resistant bacterial infections, including respiratory tract infections. The aim of this study was to evaluate the antimicrobial activity of EOs obtained from several samples of , and cultivated in Poland. EOs were analyzed by GC-MS and tested against four bacterial strains: (MRSA), , and .
