Copper-based alloys promise to reduce the survivability of human coronaviruses on fomite surfaces. As the global economy begins to recover from SARS-CoV-2, engineered passive antimicrobial materials are essential to protect against fomite surface to human transmission of current and future viral diseases. Though previous literature has considered copper for its antimicrobial properties, the details of time-dependent copper alloy corrosion mechanisms and its effects on cation release are not fully understood. Moreover, it is becoming clear that the media in which the viral inactivation test is carried out can impact the results. Here we test the efficacy of copper alloys in various media, including artificial perspiration, assay media, and phosphate-buffered saline. We investigate the surface chemistry, copper release, and each surface's electrochemical properties. The surfaces' antiviral performance is judged by virus unit death over time, evaluated alongside the respective surface states to identify the corrosion mechanics with the greatest antimicrobial efficacy.
