Abstract

This Letter describes an interferometric technique based on the principle of coherence multiplexing for multichannel, label-free biosensing applications. Multiple biosensors can be interrogated simultaneously with a single spectral-domain, phase-sensitive interferometer by coding the individual sensograms in coherence-multiplexed channels. The experimental results demonstrate the multiplexed quantitative biomolecular interaction of antibodies binding to antigen-coated functionalized biosensor chip surfaces. The described technique also applies to a variety of other distributed and multiplexed sensing applications besides biosensing.
