Abstract

Here we show how new developments in the area of microfluidics open the way to cheap point-of-care (POC) diagnostics for infectious diseases using acoustic and electromagnetic waves to perform on-chip sample processing. More particularly, we show how the use of phononic structures can bring efficient acoustic microfluidics, to a disposable and versatile platform, using low powers[1]. Phononic structures are arrays of mechanical feature that shape the acoustic field, in a similar fashion as that of photonic crystals with light. This enables simple integration of fluidic functions (actuated by surface acoustic waves – SAW) onto a single disposable device, by using frequency (or pitch) as a handle to select between the different functions. This is completed by optically induced dielectrophoresis (Optoelectronic Tweezers[2], OET) to specifically separate and lyse particles or cells based on their electrical properties.
