Prostate Cancer is a main cause of death among the American male population. Over ten billion USDs are spent to treat prostate cancer patients per year in the USA. Current remedies for this disease include surgery, chemotherapy, radiation therapy etc. which are not efficient and have adverse side effects. An alternative treatment called photo thermal therapy for prostate cancer has been recently introduced by researches. This technique uses elevated temperatures to destroy cancer cells. Progress of this method can be effectively monitored by Surface Enhanced Raman Spectroscopy (SERS).

This seminar will focus on a SERS technique associated with popcorn-shaped gold nano particles which are specially designed to target human prostate cancer cell line LNCaP. This technique can be used to obtain enhanced Raman spectra of cancer cells aggregated with popcorn-shaped gold nano particles. And also, destruction of cancer cells during Photo-thermal therapy can be monitored using this technique. The results indicate that SERS provides significant enhancement to Raman signal intensity which makes it a highly sensitive technique to study cancer cells.
