• prepared using a wet-milling method with zirconium balls to enhance bioavailability and expand potential applications. The particle size and physicochemical properties of the BerNPs were analyzed using field-emission scanning electron microscopy (FE-SEM), UV–vis spectroscopy, X-ray diffraction, and Fourier

• -transform infrared spectroscopy. The broth dilution method was used to determine the antimicrobial activity of the BerNPs against Streptococcus mutans (S. mutans). The impact of the BerNPs on the cell surface of S. mutans was evaluated through FE-SEM analysis, focusing on its ability to inhibit biofilm
