IISc B’luru develops air filter using green tea ingredients to kill germs


Researchers at the Indian Institute of Science, Bengaluru, have developed germ-destroying air filters that can inactivate germs using ingredients like polyphenols and polycationic polymers commonly found in green tea. These ‘green’ ingredients rupture the microbes through site-specific binding. The technology has been transferred to antimicrobial air purifier-maker AiRTH for commercialization.
