Abstract Bacterial infections are well recognised to be one of the most important current public health problems. Graphic Abstract. Use our pre-submission checklist Avoid common mistakes on your manuscript. Introduction Multidrug resistant bacteria are recognised as one of the greatest threats to human health worldwide.

Atomic force microscopy AFM measurements The Smooth silicone samples were immobilised on microscopy slides as solid supports in order to prevent slipping during ongoing AFM measurements. Contact angle measurement Silicone surfaces of the type Smooth, Mesmo and Polytxt were coated with eADF4 C16 or tested uncoated with four aqueous liquids, namely, ultrapure water, 0.

Bacteria culture Brevundimonas diminuta DSM and Ralstonia pickettii DSM were plated from cryostocks on plate count agar PCA plates and incubated for 2 days at 29°C. Scanning electron microscopy SEM To analyse the morphological structure and bacterial infestation using SEM, the surfaces were fixed in paraformaldehyde solution 3.

Table 1 Surface hydrophilicity of uncoated and silk-coated silicone surfaces with different textures Smooth, Mesmo and Polytxt was determined using contact angle measurements. Full size table. Figure 1. Full size image. Figure 2.

Figure 3. Conclusion Coatings of silicone surfaces made of recombinant spider silk eADF4 C16 improved wetting of such surfaces using different pre-surgical aseptic solutions, which in combination with spider silk´s repellence properties enhances their applicability against opportunistic bacterial strains associated with inflammation.

According to Health Canada, antibiotic resistant superbugs are currently the fourth leading cause of death in our country — a problem experts expect to get a lot worse as more bacteria evolve resistance to our current roster of antibiotic medications.

If you were to zoom right down to the surface of the lotus leaf, you'd see a structure kind of like a series of rolling hills, covered in trees and then flowers on those trees.

This surface is slippery because these structures trap air pockets between themselves and water droplets, for example. The water droplets then slide like pucks on an air-hockey table.

Didar and his colleagues created a surface that emulates this. In includes microstructures 10 times smaller than the width of a human hair, which he said are the equivalent of the rolling hills. On top of the microstructure, they added nanostructures times smaller than a human hair that you can think of as the trees.

Then on top of that layer, they added Teflon-like fluorinated chemicals to mimic the lotus leaf's waxy layer, equivalent to the flowers on the trees. In total this structure works much like the lotus leaf, and bacteria find it as slippery and hard to stick to as water droplets.

Didar and his McMaster University colleagues tested their self-cleaning surface with three different superbugs: Staphylococcus aureus MRSA , Pseudomonas aeruginosa and E. Their material prevented approximately 90 per cent of the bacteria from attaching to the surface, but more importantly, they were able to prevent the formation of biofilm, which Didar said is key to prevent contamination that would allow another person to pick up and transfer elsewhere.

A novel engineered surface material called RepelWrap is offering great promise in medical settings — among myriad other uses. Its structure, inspired by the water-repellent properties of lotus leaves, makes it extremely liquid-repellent — which prevents pathogens from adhering to it.
