A new way of carcinoma treatment comprises the use of gold nano shells on carboxylated polystyrene spheres (GNCPSs). The gold nano particles can perform an efficient conversion of light that is absorbed by them into heat energy and this makes them suitable for use as selective photo thermal agents in molecular cancer cell destruction.

The nano particles are first applied on the cancerous tissue and then treated with a low dose of light of frequency 808 nm or visible light argon laser. By doing this it has been seen that the cancerous tissue can be destroyed with the use of less than half the energy required in the methods being used right now. The rate of cancer cell elimination is also found to be higher.
