3D- Printed Modular SPR Platform Integrated with Ellipsometer for In-situ Label-free Optical Sensing Applications

Abstract

<p>We present the instrumentation of highly sensitive, label-free and nondestructive Surface Plasmon Resonance-enhanced Ellipsometry (SPRE) technique using the efficient 3D printing technology and its applications for the sensitive detection of biochemical analytes. SPRE offers the advantages of both SPR and Ellipsometry while eliminating the limitations encountered with each individual method. </p>
