Abstract
En 中文
Future healthcare and precision medicine require multiplex and reliable biosensors. Here we present a compact photonic crystal based microdisk biosensor that is designed for simultaneous intensity and phase measurements of multiple biomarkers in parallel. The combination of two different measurement approaches has a range of advantages. Phase detection has higher signal to noise ratios, while intensity measurement helps to align the sensor to high phase sensitivities and increase the reliability. The performance of the microdisk biosensor system is examined by simulations and measurements. For proof of concept, parallel intensity and phase shifts are measured upon binding of human-alpha-thrombin and streptavidin.(c) 2023 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
