What is it about?

The topography and wettability of the underside of English weed (Oxalis pes-caprae) leaves was studied using epoxy replicas created via a two-step casting process. Leaves were found to be close to super hydrophobic due to the presence of a characteristic pattern of irregular 100 µm – 200 µm × 60 µm convex papillae.

Why is it important?

The water repellency properties of the microstructured surfaces of the English weed leaves may have important applications, including self-cleaning, anti-microbial and anti-fouling.
