Real time dental resin curing dynamics monitoring with surface plasmon resonance

在这个项目中，我们建议使用高精度的表面等离子体共振（SPR）为基础的光学传感器技术监测牙科树脂固化动力学在真实的时间。我们将探索两种线性SPR传感模式，其中反射光波的强度下降的位置在SPR条件下监测和非线性SPR传感模式。非线性SPR传感器的工作原理是基于最近发现的当用宽带多色光照射树脂时，在SPR条件附近的和频反射波的PI光谱开关。我们希望这项新技术能为我们的工业合作伙伴BlueLight Analytics提供一个高度准确的工具，以确定各种牙科树脂和光固化装置的适当固化时间。

In this project, we propose to monitor dental resin curing dynamics in real time using a highly accurate surface plasmon resonance (SPR) based optical sensor technique. We will explore both linear SPR sensing modality, where the position of an intensity dip of a reflected light wave is monitored under the SPR condition and a nonlinear SPR sensing modality. The nonlinear SPR sensor operation principle is based on recently discovered by the PI spectral switches of sum-frequency reflected wave near the SPR condition when the resin is illuminated with broadband polychromatic light. We expect the novel technique to furnish our industrial partner, BlueLight Analytics with a highly accurate tool to determine the proper curing time for a wide set of dental resins and light curing units.
