Camellia sinensis tea buds are not only cheap, biodegradable, but also porous in their natural form. < / P > < p > researchers from Guwahati Institute of technology in India, led by Professor Dipankar Bandyopadhyay, began grinding the buds to separate out porous particles that could be produced. Then they coated the particles with magnetic nanoparticles. < / P > < p > the modified tea bud granules, called t-budbots, were eventually placed in a bacterial biofilm grown in glassware. By using magnets, scientists can guide particles through these membranes. When t-budbots move, they can penetrate the coating, kill bacteria, and remove biofilms. < / P > < p > Bandyopadhyay and colleagues are happy with their proof of concept study, but they point out that the technology needs to be further refined before it can be used in implants or other objects in the human body. Epic Games accused Google of monopolizing the latter, which may have a better chance than apple
