Label-free optical biosensors are powerful tools for the real-time monitoring of both
molecular and cellular-scale interactions. Resonant waveguide grating biosensors are
based on the detection of refractive index changes induced by molecular interactions
and/or cell mass redistributions. The Epic BenchTop and Epic Cardio are two biosensors
with high sensitivity and throughput that offer excellent potential for life science
research. Both instruments are suitable for cell-based and biochemical assays. In
this paper, I describe the principles of operation and performance of the Epic BenchTop
and Epic Cardio label-free waveguide grating biosensors and discuss their applications
in various research areas.
