The Challenge

Surface contamination affects multiple industries and can be costly and time-intensive to treat. An estimated 3.58T L of fresh water (enough to sustain 68% of the global population’s drinking needs) is used to flush waste away each year in the US. Reducing the labor, cleaning chemicals, and flush volumes required to keep toilets and other surfaces clean has enormous global water and energy-saving potential.

Innovation Details

spotLESS is a sprayable coating that repels liquid, sludge, bacteria, mineral deposits, and more. It contains a liquid-infused nanosponge that was inspired by the slippery surface of the pitcher plant. spotLESS can keep surfaces like toilets clean, drastically reducing the amount of water and cleaning chemicals required. It is available for home use, and can be sprayed onto glass and ceramic at ambient conditions.

Biomimicry Story

Pitcher plants trap insects and other small prey when they land on the rounded rim of the pitcher and fall in, ending up in a pool of digestive juices. The surface of the rounded rim is especially slippery, making it difficult for insects to grab hold and escape. The pitcher owes its slipperiness to a thin wet film on the surface, which drastically reduces friction between the plant and insect feet.
