Description: Most people believe that "cotton is naturally antistatic." The opposite is true: below 40% relative humidity, the surface resistance of cotton surges from 10⁹ Ω to over 10¹³ Ω, making it no different from synthetic fibers. Current solutions are either not wash-durable, uncomfortable, or too costly — none achieves the combination of being green, durable, and practical. The NENU-China 2026 team from Northeast Normal University provides the answer: CottonStatic — a bio-based antistatic treatment for cotton textiles built on synthetic biology. We engineered a CBM3a‑PaPilA fusion protein. Upon spraying, CBM3a anchors the protein onto the cotton fiber surface, while PaPilA self‑assembles into a conductive nanowire network, providing a charge dissipation pathway. Spray it on, let it dry, and the static hazard is eliminated. This protein‑nanowire network also offers a basic conductive scaffold for future flexible wearable electronics. We preserve cotton's inherent softness, maintain next‑to‑skin comfort, and avoid environmentally harmful chemical treatments. Through synthetic biology, we weave safety into every natural fiber — so that static electricity is no longer a threat.
