Abstract
Aim: Fabrication of nanopepper (NP) for antibacterial application and elucidation of its molecular and cellular biocompatibility. Materials & methods: Synthesis of NP was achieved using a high-energy ball milling method. Following characterization, its antibacterial activity and cellular and molecular biocompatibility were evaluated in vitro by experimental and computational approaches. Results: A total of15h of milling pepper produced NP with a size of 44±12nm and zeta potential of -22±12mV. Bulk pepper and NP showed antibacterial activity and an LC50 of 1.9μM and 2.1μM in HCT116 colon cells. Components of pepper, piperineand β-caryophyllene were found to interact with superoxide dismutase [Cu-Zn] and apoptotic protease-activating factor-1-caspase-9 through different amino acids via H-bonds. Conclusion: NP exhibits significant antibacterial activity with cellular biocompatibility due to intrinsic atomic interaction.
