Droplet Production (IMAGE)
Caption
Micro-droplet production and real-time observation on a microfluidic platform. Micro-droplets are collected in a chamber where their activity can be microscopically monitored in real time, including quantifying the enzymatic activity by measuring NADPH fluorescence. Using the bright field the droplets are located and the photosynthetically active membranes can be seen. These membranes are fluorescent when excited. The droplet populations are distinguished using a coding dye, which is observable when the droplets are excited by a specific wavelength (550 nm). The NADPH production of the droplets is observed using NADPH fluorescence (using, 365 nm).
