A commonly-used biomimetic strategy attempts to copy Nature when designing the structure and properties of materials. As an alternative to this strategy, we directly use Nature (in the form of viable bacterial cells) to add functionality to waterborne coatings.

A commonly-used biomimetic strategy attempts to copy Nature when designing the structure and properties of materials. As an alternative to this strategy, we directly use Nature (in the form of viable bacterial cells) to add functionality to waterborne coatings. Specifically, we have successfully made “biocoatings,” which confine non-growing, metabolically-active bacteria (including Escherichia coli) within a synthetic colloidal polymer (i.e. latex) film. We have used nanomaterials, such as halloysite, to ensure a network of pores to allow mass transport into and out of the material. I will describe our optimised film formation process to achieve biocoatings for the denitrification of wastewater.
