A microfluidic device was created by IMB that is capable to sort microscopic particles down to 20nn. This will enable scientists to separate exosomes from body fluids and will be able to serve as trackers for biomarkers for cancer and other diseases.

Cell membranes release Exosomes that contain genetic and protein information, these can be spotted in cancer cells also. This is important  with regards to the goal of developing liquid biopsies from blood samples.

Deterministic Lateral Displacement (DLD) pillar array is used by the new IBM microchip. Exosomes from other sample components are separated by this new technology and  accurately sort based on size.

Scientists will be able to compare exosomes and study these exosomes giving them the capability in source identification. Although not exactly a cancer detector, early diagnosis and screening of the variety of cancer is Made possible.

The microchip is already being tested in helping the early diagnosis of prostate cancer doing away with traditional biopsies..
