In a recent study conducted at Swansea University, scientists have accidentally discovered that nanoparticles derived from tea leaves can be used to cure lung cancer. Nanoparticles are extremely small particles (of the size between 1 to 100 nanometers) and have shown immense capabilities in the medical field.
In a joint project comprising of Indian scientists and research team at Swansea University, research was conducted on quantum dots (nanoparticles which are just 4000th the thickness of human hair). To the amazement of the scientists, it was discovered that a quantum dots manufactured from tea leaves entered the cancer cells and killed a staggering 80% of them.
The role of tea leaves:
Quantum dots are synthesized chemically and hence can have toxic side effects. The Swansea research team, therefore, manufactured quantum dots using tea leaf extract. It is well known that tea leaves have a variety of polyphenols, amino acids, and various antioxidants. So when quantum dots were manufactured using tea leaves extract, the dots penetrated the nanopores of cancer cells, inhibited their growth, and destroyed up to eighty percent of cells. Besides, using tea leaves for the manufacture of quantum dots is 25 to 50 times cheaper than synthesizing it chemically.
The way forward:
Though the research is very promising, it is still in the nascent stage. The scientists are of the opinion that more research is needed, particularly to find out the role of tea leaf extract in cancer imaging, and the interface between quantum dots, and cancer cells. It will take some time to refine the research and scale up the operations so that the benefits of research are commercially available.
