Demonstration of a freely positionable fibre-optic coupled probe for SERS-based sensing of an explosive analyte over a Ag nanopyramid substrate fabricated by nanoimprint lithography
Sensing of explosive molecules for defence application was done using freely positionable and fibre coupled Raman probe. We developed the highly sensitive Ag-based array of surface enhanced Raman substrate (SERS) using a nanoimprint lithography. A limit of detection (LOD) as low as 10–9 M for Cyclotetramethylene-tetranitramine (HMX) was achieved with long distance detection of 10 m. The optical fibre length could be customized from 1 to 10 m. This is the upcoming remote technique for sensing, using fibre coupled Raman probe, containing 20x objective present just in front of the optical fibre, so that the background signal does not dominates. An enhancement factor of 3.11 × 106 was achieved with the limit of detection as 10–9 M and it finds useful application in defence and medical field.
期刊介绍：
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
