Quantum dots are important for cancer patients as these dots actively inhibited the growth of the lung cancer cells. Yes, it can be made chemically, but this is complicated and expensive and has toxic side effects. A team of Indian and British scientists has found that tea leaf extract can be a non-toxic alternative to making quantum dots using chemicals. Sudhagar Pitchaimuthu from Swansea University has shared that our research confirmed it. Nanoparticles derived from tea leaves can work well in case of lung cancer.

This team also had researchers from KS Rangasamy College of Technology and Bharathiar University in Tamil Nadu. As per their research, tea leaf extract with cadmium sulphate (CdSO4) and sodium sulphide (Na2S) can form required quantum dots.

The CdS quantum dots derived from tea leaf extract showed exceptional fluorescence emission in cancer cell bioimaging compared to conventional CdS nanoparticles.

The study found that quantum dots produced from tea leaves inhibit the growth of lung cancer cells and destroyed up to 80% of them.
