In this study, we employed a new technique using thin fibers to generate and transfer picoliter droplets. When the fiber is dipped in aqueous solution and subsequently pulled up, a picoliter-sized droplet is formed at the end of the fiber. To avoid evaporation effects, the whole process is carried out under a covering layer of liquid fluorocarbon. In order to fundamentally understand the nanofluid dynamics occurring at the fiber ends, we examined the snap off process and observed influence of withdrawal speed and fiber diameter upon the droplet volume. Initial experiments show that the droplet volume is strongly dependent on the fiber diameter but not on the withdrawal speed. We also observed that the fiber sidewall wettability is an important parameter influencing droplet dynamics.
