University of São Paulo researchers reported that 3-20 MHz ultrasound sharply reduced SARS-CoV-2 and H1N1 viral loads in lab-grown infected cells by rupturing the viruses' outer membranes.
The effect comes from acoustic resonance: spherical, enveloped viruses trap sound energy until mechanical stress breaks them apart, while frequencies similar to diagnostic imaging avoid harmful heating and leave human cells intact.
Because the method targets viral geometry rather than proteins, the team said mutations such as Delta or Omicron should be less able to evade it, and the approach may extend to dengue, Zika and chikungunya.
The work, published in Scientific Reports, remains limited to in-vitro experiments, and researchers said much more testing is needed before any clinical use inside the human body.
Beyond the lab, could this virus-shattering ultrasound one day treat infections directly inside the human body?
Does shattering viruses with sound leave behind harmless debris, or could the fragments trigger dangerous immune responses?
Sound Waves vs. Viruses: A 2026 Revolution in Non-Chemical Antiviral Strategies
Overview
In May 2026, a major scientific breakthrough was achieved by a diverse team of experts who joined forces to physically destroy viruses using sound waves. This innovative research, led by scientists from the Institute of Physics of São Carlos and supported by theoretical physicists, acousticians, and medical specialists, marks a pivotal moment in antiviral strategies. Their interdisciplinary collaboration has opened a new era in combating viral threats, showing that targeting viruses with sound waves could offer a powerful, non-chemical approach to fighting infections. This breakthrough highlights the importance of teamwork across different scientific fields to solve complex health challenges.
