British scientists have developed a new way to scan tissue using high-resolution sound and without damaging cells. The research was published in the scientific journal magazine Photoacoustics.
The technology called photon microscopy is based on the use of sound waves with a frequency of 10.9 Hz, which is 1000 times higher than traditional medical ultrasound. Such micro-oscillations are created by ultrafast lasers.
Since such sound waves are not naturally focused, the team also developed special optoacoustic lenses to create clear 3D images.
According to the researchers, this discovery will allow real-time monitoring of cell cycle processes, cancer cell progression and intracellular effects of various drugs at the nanoscale.
Additionally, acoustic microscopy does not require fluorescent labels and harmful chemical dyes that are required for analyzes using optical microscopy. Experts stated that the method will make it possible to prevent tissue damage.
Previous scientists was created Nanosensors to diagnose lung cancer using exhaled air.
