Photonic Crystal Fiber for Chemical Sensing Using Surface-Enhanced Raman Scattering
- Pp. 157-179 (23)Yun Han and Henry Du
The unique feature of photonic crystal fiber (PCF) both as a light guide and a gas/liquid transmission cell allows synergistic integration of optics and microfluidics. There is a growing interest in PCF as a platform for spectroscopy-based chemical and biological sensing. In this chapter, we focus on PCF for sensing and detection using surface-enhanced Raman scattering (SERS). We examine the state-of-theart, challenges and opportunities in the development of SERS-active PCF sensors.
