Droplet microfluidics has emerged as a prospering field for lab-on-a-chip devices, where droplets serve as liquid vessels e.g. for biochemical reagents. Key to the fluid processing in droplet format are the controlled droplet handling and movement on the microscale. Hence this paper proposes droplet handling by combining droplet microfluidics with bulk acoustic wave (BAW) acoustophoresis. BAW

The process is applicable to healthcare applications Optofluidics is a merger of the fields of optics and microfluidics. Recent research has shown, that there are two main particle manipulation techniques widely discussed-active (e.g., acoustophoresis) [3, 5] and passive (e.g., internal microfluidics) [6,7], both of microparticles in droplet microfluidics using two-dimensional acoustophoresis M Ohlin et al-A spatiotemporally controllable chemical gradient generator via acoustically oscillating sharp-edge structures Po-Hsun Huang et al-On-chip ultrasonic sample preparation for cell based assays Bioparticle Manipulation using Acoustophoresis and Inertial Microfluidics . By Muhammad Asim Faridi. Abstract. Despite the many promising advances made in microfluidics, sample preparation remains the single largest challenge and bottleneck in the field of miniaturised diagnostics. Recently, acoustophoresis has been used in microfluidics to manipulate microparticles inside moving droplets.
Acoustophoresis Acoustophoretic particle focusing is a modern and very attractive method of removing a variety of objects from solutions in a microfluidic channel.
