Abstract BACKGROUND: Clove oil has a wide range of therapeutic and pharmaceutical applications. It is also used in the manufacture of pesticides and antifungals, as well as many advantages. The study aims to improve the properties of essential oils, especially clove oil, and make them more stable by the design of delivery systems (nanoemulsions and biopolymer nanoparticles). METHODS: Clove oil was mixed with water in the presence of tween-20 as a polysorbate-type nonionic surfactant, and then carboxymethyl cellulose was added with different ratios of glycerin as a cross-linking agent. The formation of the clove nanogel was tested by spectrophotometric assay 2.2.2 Fourier transform infrared spectroscopy (FT-IR), Proton Nuclear Magnetic Resonance Spectroscopy ( 1 H-NMR), dynamic light scattering (DLS), and morphology method field emission scanning electron microscopy (FESEM), also the rate of clove oil release during different periods, and hemolytic and antioxidant activity were tested. RESULTS: The nanoparticles were demonstrated by DLS and FESEM. The polydispersity index value was 0.279, indicating good monodispersity and good stability, while higher release values were obtained when glycerol was not present as a cross-linker. In addition to the higher antioxidant, values of the clove oil nano emulsion (CNE) have a maximum inhibition of 65% at a concentration of 100 μg/mL, whereas clove nano-gel (CNG) at the same concentration exhibited 59.2% inhibition. The calculated IC50 values of CNG and CNE were 6.58 and 3.25 μg/mL, respectively. CONCLUSION: The study proved through the results obtained that nanocomposites help stabilize components, especially volatile oil, which increases their effectiveness.
