Green tea to fight lung cancer

摘要

Researchers from Swansea University have found that quantum dots made from green tea could be a powerful weapon in the fight against lung cancer.Quantum dots are nanoparticles used in everything from computers and solar cells to tumour imaging. They are usually made using synthetic chemicals, but the process can be expensive and sometimes results in toxic side effects.In the search for a plant-based alternative, theSwansea team mixed green tea leaf extract with cadmium sulphate (CdSO_4) and sodium sulphide (Na_2S). The solution was allowed to incubate, causing quantum dots to form. Working alongside two Indian universities, the UK-based researchers were initially able to back up previous work conducted on quantum dots made using tea leaves.
