Playing with actuators in microfluidic systems
In the lab-on a chips of the future, flows will be handled at the microscale through mazes of microchannels. For such systems, it will be crucial to integrate a number of actuators on the chip [...]

Controlled production of food emulsion using microfluidics
We present Microfluidic technology applied to the production of monodisperse emulsion in a food context. We investigate the effect of surfactants and microdevice geometry on drop size and robust production regimes. Minimum drop size achievable in [...]
A Lab-on-a-Chip using Magnetic Droplets
We present a chip-based bio-analysis system using the two dimensional (2D) magnetic manipulation of microdroplets. The latter contain magnetic microparticles which serve as force mediators for the droplet actuation. In combination with a changeable field [...]
Acorn™, a New, Simple, Inexpensive Method for Non-Invasive Particle Size Measurement of Suspensions and Droplets
Nanoscale particle sizing of colloidal suspensions can be performed with Acorn,™ a new, patented handheld device, that combines remote delivery and detection of laser light, and a direct measurement of particle size, without the use [...]
A Droplet Microarray for Homogeneous Enzymatic Assay
This work describes a droplet microarray for monitoring of enzymatic activity on a glass slide. These array are composed of features defined and separated by differential surface tension (surface tension array). A photolithographic method was [...]
Simulation of a Polymer Drop in a Shear Field with Dissipative Particle Dynamics Method
In the present study, the dynamics of polymer drops in micro channel under both steady state and transient shear flow conditions are investigated using Dissipative Particle Dynamics method. The polymer drop is made from finitely [...]
