The possibility of detecting viruses in biomedical research using the optoacoustic method with carbon nanotubes is considered in the paper. In this paper, we consider the setup used to detect optoacoustic responses from a sample, which allows the recording of optical-acoustic signals generated by carbon nanotubes attached to the surface of viruses in the blood and which have high optical absorption. When the sample is irradiated, the absorbed energy from the laser radiation is converted into kinetic energy by means of energy exchange processes. This leads to local heating and, consequently, to the appearance of a wave of sound pressure. By recording ultrasonic waves, it is possible to form a spectrum of the optoacoustic signal for the test sample, which can be used to detect the absorbing components in it.
