Measuring photon-upconversion luminiscence from droplets in microfluidic chips
 Hlaváček, Antonín ; Křivánková, Jana ; Přikryl, Jan
UCNPs are lanthanide-doped nanocrystals that can be excited by near-infrared light and emit light of shorter wavelengths. Advantages of UCNPs include multiple and narrow emission bands, negligible autofluorescence and high photostability, which make UCNPs ideal luminescence label for use in droplet microfluidic. Here, we introduce the instrumentation for reading photon-upconversion luminescence of nanoparticles, which are dispersed in water droplets in a microfluidic chip.

Compact device for fluorescence measurement by optical fiber in microfluidic chip
 Ježek, Jan ; Pilát, Zdeněk ; Zemánek, Pavel
In our paper we present a device that combines fluorescence spectroscopy with fiber optics. The device allows high speed detection (in the order of kHz) of the fluorescence signal, which is coming from the sample by an inserted optical fiber, e.g. from a micro-droplet flow in a microfluidic chip, from the liquid flowing in the transparent capillary, etc. The device uses a laser diode at a wavelength suitable for excitation of fluorescence, excitation and emission filters, optics for focusing the laser radiation into the optical fiber, and a highly sensitive fast photodiode for detection of fluorescence.
