a) Overlay of the resonance wavelength shifts of a representative microring to several concentrations of target DNA. The dotted lines indicate the functions fit to the initial binding response from which the initial slope of the sensors was determined via differentiation. b) The plot of sensor initial slope versus target concentration yields a response relationship that is linear over an ~3 order of magnitude dynamic range. The inset is an expanded version of the same plot showing the lower concentration range.
