Droplet-based microfluidics at the femtolitre scale

Lab on a Chip, 2015
Standard operations of droplet-based microfluidic were miniaturized down to the femtolitre scale. The level of control is maintained despite the three order of magnitude reduction in droplet volume.

Microgel Capsules Tailored by Droplet‐Based Microfluidics

ChemPhysChem, 2012
AbstractMicrogel capsules are micrometer‐sized particles that consist of a cross‐linked, solvent‐swollen polymer network complexed with additives. These particles have various applications, such as drug delivery, catalysis, and analytics. To optimize the performance of microgel capsules, it is crucial to control their size, shape, and content of ...

Sample preparation for droplet-based microfluidics

2014 International Symposium on Integrated Circuits (ISIC), 2014
Sample preparation plays an essential role in most biochemical reactions. Raw reactants are diluted to solutions with desirable concentration values in this process. In this paper, a survey of existing techniques addressing sample preparation on digital microfluidic biochips (DMFBs) is given. The fundamentals of DMFBs are introduced first.

Droplet-based microfluidics for drug delivery applications

International Journal of Pharmaceutics
The microfluidic method primainly utilizes two incompatible liquids as continuous phase and dispersed phase respectively. It controls the formation of droplets by managing the microchannel structure and the flow rate ratio of the two phases. Droplet-based microfluidics is a rapidly expanding interdisciplinary research field encompassing physics ...

Digital microfluidics: Droplet based logic gates

Applied Physics Letters, 2007
The authors present microfluidic logic gates based on two-phase flows at low Reynold’s number. The presence and the absence of a dispersed phase liquid (slug) in a continuous phase liquid represent 1 and 0, respectively. The working principle of these devices is based on the change in hydrodynamic resistance for a channel containing droplets.

Stochastic Computing Using Droplet-Based Microfluidics

2018
In this work, we consider the realization of stochastic computing in the microfluidic domain. To this end, we exploit the fact that both, the bit streams and the operations required for stochastic computing can be realized in microfluidic systems through droplet streams and microfluidic gates.
