👉 The needle fluid, also known as microfluidics or droplet-based fluidics, is a specialized fluid used in microfluidic devices to manipulate and control the movement of tiny volumes of liquid, typically in the nanoliter or picoliter range. These fluids are engineered to have unique properties that enable precise control over their behavior, such as low viscosity, high surface tension, and the ability to form stable droplets. By using needle fluidics, scientists and engineers can perform complex operations like mixing, separation, and chemical reactions at the microscale, which is crucial for applications in diagnostics, drug delivery, and materials science. The fluid's small size and controlled dynamics make it ideal for handling delicate biological samples and ensuring high accuracy in lab-on-a-chip technologies.
