Abstract

The ultimate challenge for early diagnostics is labelfree high-resolution intratissue imaging without taking physical biopsies. A novel hybrid femtosecond laser tomograph provides in vivo optical biopsies of human skin based on non-linear excitation of autofluorescence and the detection of lipids and water by CARS. Applications include skin cancer detection, biosafety tests of intradermal nanoparticles, and the testing of anti-aging products.
