Nanotechnology refers to the use of ultra-small particles measured in nanometers — one billionth of a meter. In MicroSURE, this technology creates a protective layer made of spike-like structures just 4 nanometers in size — far smaller than viruses (~100 nm), bacteria (~1,000–10,000 nm), and fungi (~2,000–100,000+ nm).

Because these nano-spikes are smaller than microbes, no virus, bacteria, or fungus can pass through the MicroSURE layer — and instead, they are physically ruptured and destroyed on contact. At the same time, this barrier supports skin healing, enhances hydration, and provides long-lasting, chemical-free protection — making it ideal for sensitive or compromised skin.
