Abstract

 In this work, we evaluated the use of laser-induced breakdown spectroscopy (LIBS) coupled with chemometric methods as a fast and simple technique for identifying diseased tissue in prostate cancer samples. The experimental setup consisted of a neodymium-doped yttrium aluminum garnet (Nd:YAG) laser in a burst-mode regime, with differing time delays for the spectrometer readings. To improve classification accuracy, principal component analysis (PCA) was coupled with neural analysis (NA), achieving a high identification accuracy of 97%. It can be concluded that LIBS has the potential to serve as a technique for the detection and diagnosis of human prostate cancer.
