Driving down the Detection Limit in Microstructured Fiber‑Based Chemical Dip Sensors
We present improvements to fluorescence sensing in soft-glass microstructured optical fibers that result in significantly improved sensitivity relative to previously published results. Concentrations of CdSe quantum dots down to 10 pM levels have been demonstrated. We show that the primary limitatio...
