Background-free optical coherence tomography imaging with gold-seeded growth on magnetically responsive nanorods (Conference Presentation)

Paper Abstract

Optical coherence tomography (OCT) allows for imaging of fine structures below the surface of tissue based on inherent contrast from heterogeneity of optical refractive index. A contrast agent may be used when intrinsic contrast of a target in the sample is not enough. We synthesize magnetically-responsive nanorods whose reflectivity can be modulated by the orientation of a magnetic field and demonstrate their use in background-free OCT imaging. Because normal tissue does not respond to switching magnetic field, the signal from nanorods can be isolated from tissue.
