Abstract :
We investigate the effect of volume and size of silver nanoparticles (AgNP) on surface enhanced Raman scattering (SERS) signal of rhodamine 6G (R6G) within hollow core photonic crystal fiber (HC-PCF). The HC-PCF enhanced the Raman signal of R6G by a factor ~90 via photonic band gap. In addition, the optimal size and volume of AgNP enhanced the Raman signal of R6G by a factor of ~43, resulting in a total enhancement of ~4223 in HC-PCF. A comparison of AgNP enhancement factors in HC-PCF and bulk sample (cuvette) is presented at their optimal size and volume with respect to R6G. The SERS based HC-PCF sensing platform as optimized for R6G as a test molecule, was further utilized for monitoring adenosine for clinical application.
