Development of Photoacoustic Screening Device for Potential Oral Cancer Application

Suhel Khan, Srivathsan Vasudevan

Abstract: This paper proposes the development of a label-free photoacoustic screening device to be used as an oral cancer application. Acoustic spectral response of the tissue sample would be acquired through the developed photoacoustic system and the signals would be used as a signature to determine the pathology of the tissues. The development would also make this setup portable so that it can be taken up for the oral screening.
