A novel process for uniform deposition of noble‐metal catalyst nanoparticles on the inner core wall of a hollow‐core photonic crystal fiber is presented. The resulting continuous flow microreactor enables heterogeneous catalysis reactions on extremely low (sub‐μL) sample volumes. Strikingly, the excellent single mode transmission properties of the HC‐PCF are preserved after the deposition process, allowing sensitive in situ spectroscopy measurements over unprecedented length scales of up to 50 cm.
