A Critical Call for Mechanistic Investigations of Metal‐Bacteria Interactions
Advanced Materials, EarlyView.It is well established that the antibacterial properties of metals have tremendous importance for bioengineering applications. What is not as appreciated, however, is the reproducibility crisis in this field's vast literature. In this perspective, we highlight this reproducibility problem, discuss its sources, and suggest solutions towards focused ...
