Abstract
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.
