Two experiments explore the application of plasmonic nanoparticles to cellular pathology. The first devised a platform by which gold-silver nanoparticles act as differentiable labels for cell surface receptors under dark field imaging. By conjugating particles of various constitutions with receptor-targeting antibodies, particles scatter characteristically according to their plasmon peak. The second experiment programmed receptor placement via the patterning of two substrates and used the binding of SERS nanoparticles to explore the quantification of such targets at high-density. On one substrate, anchor pairs established receptors at specified distances in order to define the relationship between scattering intensity and the distance between SERS particles. On the second, anchor regions are filled with increasing densities of receptors and the particle-saturated substrates are probed to relate scattering intensity to particle density. This should discover the density-threshold between linear and non-linear scattering and inform the quantification of particles in the exponential density regime. |
