It could be a non-toxic alternative to make quantum dots with chemical products, the researchers say.
A study by the University of Swansea, in the United Kingdom, has revealed that tea leaves can reduce the risk and even serve to treat cancer. More precisely, scientists discovered that they have the ability to produce nanoparticles that inhibit the growth of cancer cells.
The procedure consisted of mixing the tea leaf extract with cadmium sulphate (CdSO4) and sodium sulphide (Na2S), to obtain the formation of quantum dots. Later they applied the points to the lung cancer cells, finding a destruction of up to 80% of cancer cells.
"Our research has confirmed the previous evidence that tea leaf extract can be a non-toxic alternative for making quantum dots with chemicals," said study leader Sudhagar Pitchaimuthu.
