Paper Abstract

Raman spectroscopy (RS) is a non-destructive analytical technique, that provides a unique fingerprint of molecules with high accuracy. It proves to be a reliable and practical alternative to chemical analysis, allowing sample identification without the use of reagents. This label-free technique finds applications in quality control and in-line process monitoring, however, like any other technique RS also presents its challenges such as expensive and delicate instrumentation and complex design, which often confines the technique to the laboratory. In order to address these challenges, a 3D printed Lab-On-Chip (LOC) was fabricated and assembled with four channel optical fibres, which will collect the Raman scattering. The performance of our Raman Probe on Chip is evaluated using Isopropanol alcohol (IPA) as a validation sample.
