 Shark Skin Inspires New Antibacterial Surface Technology

In a remarkable example of biomimicry, scientists have developed a new surface coating inspired by the structure of shark skin that significantly reduces bacterial growth. This innovation could have far-reaching implications for public health, particularly in hospitals and clinics where bacterial contamination poses ongoing challenges.

The research, led by teams from the University of Nottingham and Sharklet Technologies, focuses on a micro-patterned surface that mimics the dermal denticles of shark skin. These tiny ridges naturally prevent biofilm formation by disrupting how bacteria adhere and grow. When applied to synthetic materials, the engineered surface reduced bacterial growth by up to 94 percent in lab tests.

Unlike traditional antibacterial coatings that use chemical agents, this technology relies solely on physical structure. That means it does not encourage antibiotic resistance or rely on ongoing chemical reapplication. The surface can be applied to plastics, metals, and even textiles, making it versatile for use in medical devices, hospital beds, and other high-touch environments.

Beyond healthcare, the shark skin-inspired surface could be useful in food processing, public transportation, and wearable technology. Its passive, non-toxic mechanism also makes it attractive for use in environments where frequent cleaning is difficult or expensive.

The researchers are now partnering with industry stakeholders to develop scalable manufacturing methods and conduct field trials. If successful, this nature-inspired technology could play a pivotal role in the global effort to reduce healthcare-associated infections and promote safer public spaces.
