Alzheimer's disease(AD) is a neurodegenerative dementia characterized by memory loss and cognitive impairment. The sensitive and selective detection method is required in order to early definitive diagnosis of AD. Beta-amyloid is very attractive as a potential biomarker because of its natural association with the amyloid plaque. This study was based on measuring the beta-amyloid protein concentration and Scanning Tunneling Microscopy(STM) was studied for
ultrasensitive feature measurement. STM is versatile technique to apply biosensor for beta-amyloid, because STM provides a topography and current of the atomic arrangement of a biosurface using gold nanoparticle. Gold nanoparticle immobilized on the surface has different electrical properties, it can be analyzed within nanoscale using STM. In this study, gold(Au)
nanoparticle-antibody conjugate was applied and STM current change of biosurface can be utilized as quantitative analysis. Experimental results show that the proposed measurement technique can be applied to the nanoscale investigation with respect to a variety of biosensor for diagnosis, drug discovery and on-site monitoring of Alzheimer's Disease.
