Merging of the droplets

One of the droplets contains bacteria, second antibiotic and the last buffer. Merging them together in different concentrations one can asses the critical concentration of the antibiotics.

Multiple Janus particles

Multiple Janus particles made via microfludic system.

Free-standing smectic film in external electric field

Oscialtions of liquid crystalline island in external, radial electric field. Applied voltage: 800 V, frequency: 64 Hz.

Production of emulsion via flow-focusing

Generation of water droplets in hexadecane via flow-focusing

Electro-coalescence of water droplets

An example of electro-coalescence of water droplets in hexadecane. Frequency of electric field: 300 Hz

Electro-coalescence in microfludics

Electro-coalescence of water droplets in oil. Frequency of electric field: 1 Hz

Blood analysis

The whole process enabling droplet distinction - starting with merging of blood sample with monoclonal reagents containing antibodies, the flow of droplets through the mixing channel and gradual division inside agglutinated ones.

Lipid bilayer in a microfluidic trap

The exchange of droplets in a microfluidic trap for the serial formation of lipid bilayers. The bilayer formation is seen as a change in the refraction of light at the interface between the droplets. Proper wetting and dewetting of electrodes is enabled by the unique design of a hydrodynamic trap. Thanks to the use of external electromagnetic valves we are able to precisely control the flow of droplets.
