Abstract
Label-free sensing method based on optical resonance of whispering gallery modes is one of the promising techniques for biochemical sensing at the micro- and nanometer scale [1,2]. Despite the well-researched advantages of these sensors the following improvements are required for its widespread implementation as the real world-deployable systems: long-term stability, noise suppression, multiplexing, fabrication simplification and reusability [3]. A developed chip with array of spherical resonators is one of the trade-off solutions by means of complexity, sensitivity and efficient mass production [4]. Bulk refractive index sensing or absorption monitoring is commonly used to evaluate analyte properties. Here we report on quantification of the adsorption kinetic parameters by a multiplexed optical resonance sensor. © 2019 IEEE.
