Achieving Precision in Blood Cell Separation: The Role of Deterministic Lateral Displacement and Dimensional Stability

The image below shows a blood cell separation device that uses deterministic lateral displacement (DLD), which requires sub-micron accuracy in the spacing between posts in order to maintain separation efficiency. Edge not only can produce large arrays with this type of structure, but can also maintain post height and spacing after lidding.

It is crucial for most products that their parts maintain their dimensional stability starting from the assembly process and throughout the device's lifespan. This is where our proprietary process comes in. Our components have almost zero residual stress, meaning they can maintain their dimensional stability in the long run.
