Possibilities of TOF-SIMS Approach for Biometrics

Materials used in biomedical or cosmetic application often functioned by it’s surface properties. Thus, understanding surface is critical to the design and engineering of new devices. Modern TOF-SIMS has been developed for the microelectronics and petrochemicals industry. This paper examines how TOF-SIMS can be applied to biomaterials, such as hair surface. In particular, surface redial organic on hair and penetration depth into cuticles or cortex of shampooing/rinsing component will be addressed.
