Nanomechanical characterization of human fingernail using nanoindentation and AFM

The nanomechanical properties of fingernail are characterized using quasi-static and dynamic indentation testing techniques. The results show that the storage modulus is larger than the Young's modulus and shows the dependency on the measured frequency. From the compassion between these two methods, we can get more useful information using nanoDMA. In future, we will try to link the nail properties with the bone health.EI
