Measurement of buried undercut structures in microfluidic devices by laser fluorescent confocal microscopy
Measuring buried, undercut microstructures is a challenging task in metrology. These structures are usually characterized by measuring their cross sections after physically cutting the samples. This method is destructive ...
Motion of a droplet through microfluidic ratchets
We report numerical and experimental studies on a droplet moving through an array of mirofluidic ratchets. Droplets are formed at a T junction and subsequently forced through microfluidic ratchets in the form of diffuser/nozzle ...
