Researchers at the Japan Advanced Institute of Science and Technology have developed a method of pollinating flowers using an aerial drone that emits pollen-infused soap bubbles.
With 4 mg of pollen per mL of 0.4% surfactant solution, the drones were able to create soap bubbles that each carry up to 2,000 individual grains of pollen.
The researchers demonstrated their pollination approach is scalable by equipping a drone with a bubble machine that can generate 5,000 bubbles per minute, which achieved a 90% success rate when the drone flew over flowers at two meters per second at a height of two meters.
The researchers found that it took just one bubble landing on the pistil of a flower to result in pollination.
