A new reusable micro fluid device has been designed to sort the manipulating cells and scale many other objects that will be further helping in the biomedical fields and will be more and more convenient in relation to the facilities and cost effectiveness. This is more precisely a gentle acoustic vibration that is also known as Acoustic tweezers. According to Huang who is the scientist have said that it will be having tremendous amount of capability that will be leading to  disposed after just one use . And now there is a way to separate the fluid from the device in ultrasound  producing piezoelectric substrate.
