Researchers at Finland’s Aalto University have successfully turned bacteria into a microscopic workforce of nanobots, using molds made of hydrophobic material to create incredibly intricate three-dimensional objects.
The researchers placed the Komagataeibacter medellinensis bacteria in a mould with water and the requisite amount of nutrients like sugar, proteins and air. Once sufficiently fuelled-up, the bacteria begin to produce nano cellulose structures, in line with the hydrophobic (water repellant) mold in which they were placed.
Cellulose is the main component found in the cell walls of plants and substances like wood and cotton.
This type of guided growth through the use of superhydrophobic materials, which also minimize the accumulation of dust and microorganisms, could soon be used for extremely intricate tissue regeneration and organ repair in the human body.
