Figure 2.

Frequency and intensity of signal events from time series acquisitions of SERS of different particle types for both bare functionalized particles and silica encapsulated functionalized particles in solution. The frequency of signal events relative to particle concentration is shown in (A). The baseline corrected classical least squares scores for events in (A) for B) GERTs, and C) bipyramids, and D) stars with and without silica encapsulation.
