UPLC

Scientists have found a better way to spot harmful chemicals in the body. These chemicals come from diesel exhaust. They are called amino-polycyclic aromatic hydrocarbons, or amino-PAHs for short. These are bits left behind in the body after it breaks down other harmful chemicals called nitro-PAHs.

Ever wondered how scientists check if medicines like sofosbuvir and ledipasvir are doing their job? These drugs, approved to fight chronic hepatitis C, need precise measurement. So, scientists developed a new way to do this using ultra-performance liquid chromatography (UPLC), which is quick, green,
