A Microfluidic Device for Ultrasonic Separation

A Microfluidic Device for Ultrasonic Separation
A Microfluidic Device for Ultrasonic Separation
This paper describes a microfabricated device designed to provide continuous flow filtration on a microfluidic scale. It uses ultrasound in the megahertz frequency range to concentrate particles at a single node within the flow. It has the potential to allow either clarified fluid or concentrated particle samples to be prepared and hence offers the possibility of a replacement for a centrifugal separator for microfluidic systems. It is primarily constructed using silicon and Pyrex, making it highly compatible with established microfabrication techniques. The modelling, design, fabrication and initial testing of the device are discussed, along with the potential for future developments in the area.

Abstract

This paper describes a microfabricated device designed to provide continuous flow filtration on a microfluidic scale. It uses ultrasound in the megahertz frequency range to concentrate particles at a single node within the flow. It has the potential to allow either clarified fluid or concentrated particle samples to be prepared and hence offers the possibility of a replacement for a centrifugal separator for microfluidic systems. It is primarily constructed using silicon and Pyrex, making it highly compatible with established microfabrication techniques. The modelling, design, fabrication and initial testing of the device are discussed, along with the potential for future developments in the area.
