Answer: Indian Institute of Science, Bengaluru
Notes: Recently, scientists at the Indian Institute of Science developed a glowing paper sensor to detect liver cancer. The sensor uses the green glow of Terbium to identify the enzyme beta-glucuronidase, which is a key biomarker for liver cancer. Terbium is a rare-earth metal belonging to the lanthanide series of the periodic table. It appears as a soft, silvery metal. Terbium is recovered from minerals like monazite and bastnaesite, and also from euxenite containing more than 1% terbium. It is used in solid-state devices and low-energy lightbulbs.
