Question

The following statements describe a few basic features of the interferometric reflectance imaging sensor used as a biosensing platform: A. This biosensing platform is capable of high-throughput multiplexing of protein-protein, protein-DNA and DNA-DNA interactions. B. The sensing surface is prepared by robotic spotting of biological probes that are immobilized on functionalised Si/SiO₂substrate. C. As biomass accumulates on the substrate surface, a change in the interferometric signature occurs and the change can be correlated to a quantifiable mass. D. Using this technique, picometer changes in biomass may be detected. Which one of the following options represents the combination of all correct statements?
