    Lipid-based nanoparticles, specifically cubosomes, were developed to enhance the delivery and efficacy of daptomycin against MRSA.

  • 2

    Daptomycin-loaded cubosomes demonstrated synergistic effects, killing 14 clinical MRSA isolates more effectively than daptomycin or cubosomes alone.

  • 3

    The mechanism of action involves cubosomes docking on MRSA membranes, releasing daptomycin for enhanced membrane penetration.

  • 4

    In a murine model, daptomycin-loaded cubosomes significantly reduced the bacterial burden of MRSA, indicating improved treatment potential.

    This study highlights the potential of multifunctional lipid nanocarriers to augment the bactericidal activity of existing antimicrobials.
