Sharklet surface technology
- Sharklet's surface technology is based on the unique properties of shark skin, which has evolved over millions of years to resist the attachment and growth of microorganisms
- The technology involves creating a microscopic pattern on surfaces that mimics the structure of shark skin, making it difficult for bacteria to adhere and colonize
- This biomimetic approach to surface design offers a sustainable and effective alternative to traditional antimicrobial solutions, such as chemical coatings or antibiotics
Inspiration from shark skin
- Shark skin is covered in tiny, tooth-like scales called dermal denticles, which are arranged in a distinct diamond pattern
- This unique structure creates a rough, textured surface that makes it difficult for bacteria and other microorganisms to attach and grow
- Dr. Anthony Brennan and his team studied the microscopic structure of shark skin and discovered its potential for preventing bacterial adhesion
- By mimicking this natural design, Sharklet Technologies has developed a novel approach to creating antimicrobial surfaces
Microscopic pattern design
- Sharklet's surface technology features a microscopic pattern of raised, diamond-shaped structures that are approximately 3 micrometers high and 2 micrometers wide
- The pattern is designed to disrupt the ability of bacteria to adhere to the surface, as the microbes cannot find a suitable place to anchor themselves
- The specific dimensions and arrangement of the pattern are critical to its effectiveness in preventing bacterial adhesion
- Sharklet's technology can be applied to various materials, including plastics, metals, and ceramics, making it adaptable to a wide range of applications
Mechanism of action
- The Sharklet surface pattern works by physically disrupting the ability of bacteria to adhere to the surface, rather than relying on chemical or pharmacological methods
- When bacteria encounter the microscopic diamond-shaped structures, they are unable to find a suitable place to anchor and colonize
- This physical disruption prevents the formation of biofilms, which are communities of bacteria that can be difficult to remove and contribute to the spread of infections
- By preventing bacterial adhesion, Sharklet's technology reduces the risk of microbial contamination and growth on surfaces, leading to cleaner and safer environments
Antimicrobial properties

- This high level of resistance to bacterial adhesion has been demonstrated against a wide range of microorganisms, including Staphylococcus aureus (MRSA), Escherichia coli, and Pseudomonas aeruginosa
- The technology's effectiveness in preventing bacterial adhesion is maintained over time, as the microscopic pattern remains intact and functional even with repeated cleaning and use
- By preventing the initial attachment of bacteria, Sharklet's surface technology helps to break the chain of infection and reduce the overall presence of microorganisms on treated surfaces
Comparison to traditional antimicrobials
- Traditional antimicrobial solutions, such as chemical coatings and antibiotics, often rely on the use of toxic substances to kill or inhibit the growth of bacteria
- While these methods can be effective in the short term, they have several drawbacks, including the potential for environmental contamination, the development of antimicrobial resistance, and the need for frequent reapplication
- In contrast, Sharklet's surface technology provides a physical, non-toxic solution that does not contribute to the development of antimicrobial resistance
