Living Clean: Biomimetic Strategies for Life-Friendly Antimicrobials

Conventional preservatives in water-based personal care products—such as parabens and formaldehyde-releasing systems—can effectively control microbes but often raise concerns about long-term exposure, endocrine disruption, and broader impacts on human and environmental health. This project asks how we might instead design antimicrobials that protect products while also creating conditions conducive to life.

 

Drawing on strategies from organisms like the African clawed frog, human defensins, and saffron, it explores how nature uses small, amphipathic molecules that target microbial membranes through electrostatic attraction and hydrophobic interactions. The emerging concept envisions life-friendly antimicrobials that selectively disrupt microbial membranes while minimizing collateral harm to surrounding systems.
