MRSA colonizes the skin and anterior nares and can potentially become invasive, leading to pneumonia and soft tissue infection. Additionally, MRSA can establish chronic infections in wounds and medical implants, partly due to its ability to form biofilms. Likewise, the skin commensal\n                      <jats:italic toggle=\"yes\">Staphylococcus epidermidis<\/jats:italic>\n                      also causes similar infections, particularly through its ability to form a plastic-binding biofilm.

We used Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), biomass assessment, colony counts, and metabolism assays to interrogate the state of the bacterium after exposure to metal-BMDC. Furthermore, we compared these metal complexes to the antibiotic vancomycin, one of the current therapeutics used to treat MRSA infections. BMDC enhances copper uptake in bacteria, increasing intracellular copper levels by 70-fold compared to copper alone. Copper intoxication leads to a decrease in metabolic activity that ultimately results in bacterial death. Zinc also combines with BMDC, though likely through a different mechanism, and similarly exerts bactericidal effects. Significantly, both metal-BMDC combinations effectively reduce biofilm formation and eradicate bacteria within established biofilms\n                      <jats:italic toggle=\"yes\">in vitro<\/jats:italic>\n                      , highlighting their potential as promising antimicrobial strategies against MRSA and\n                      <jats:italic toggle=\"yes\">S. epidermidis<\/jats:italic>\n                      biofilms.\n                    <\/jats:p>\n                    <jats:sec>\n                      <jats:title>IMPORTANCE<\/jats:title>\n                      <jats:p>\n                        Antimicrobial-resistant bacteria, such as\n                        <jats:italic toggle=\"yes\">Staphylococcus aureus<\/jats:italic>\n                        (MRSA) and\n                        <jats:italic toggle=\"yes\">Staphylococcus epidermidis<\/jats:italic>\n                        , are a significant cause of morbidity and mortality in vulnerable populations, contributing to an escalating health and economic burden.
