Scientists at the Max Planck Institute in Germany have unveiled the invention of spherical microspheres capable of moving through water and killing bacteria, providing a new effective method of cleaning contaminated water supplies.
Swamping through the infected water with E. coli, the new bones killed 80% of the bacteria in just 20 minutes; And because they are magnetic, they can be easily extracted from the water, writes Science Alert.
The method has a great advantage over traditional water purification methods, involving the use of chemicals, both in terms of efficiency and in terms of providing clean, bacterial and non-chemical water used to kill bacteria.
There is an urgent need to develop more efficient, innovative, cheap and robust water-cleaning methods that do not have adverse effects on the environment or on human health.
The spheres have two main components: one-half consists of magnesium, which creates hydrogen bubbles in the water and acts as a propellant. The other half is made of alternating layers of iron and gold, and above them are silver nanoparticles. The iron and gold layers catch the bacterium, and the nanoparticles destroy it. After this process, the bones can be extracted with a magnet.
