- Abstract
This paper describes a novel low power method to reduce biofilm formation in microfluidic channels. When an ultrasonic (2 MHz) standing wave is set up across a microfluidic channel (250 µm) the resulting pressure amplitude can move small particles to the pressure node or anti-node, depending on the properties of the particle. This effect has been applied to Vibrio natriegens within poly(methyl methacrylate) (PMMA) microfluidic channels and a reduction in biofilm formation has been seen over a period of a week. This is a novel low power biofilm reduction strategy.
