Bacteria can be killed by purely physical trauma and mechanical disruption
Multiple studies demonstrate that bacteria can be killed through purely physical trauma and mechanical disruption, such as ultrasonic cavitation, membrane-drilling agents, and physical contact with nanomaterials.
The retrieved papers provide robust evidence that mechanical forces, acoustic cavitation, and physical membrane disruption can effectively kill bacteria, directly supporting the claim.
