Improved Sample Prep for Protein Sorting

In a recent issue of Nature Nanotechnology, a group of researchers from the Massachusetts Institute of Technology (Cambridge, Massachusetts) have created a microchip system capable of  speeding up the separation and sorting of biomolecules such as proteins. It is hoped that this system will assist with the critical work of detecting molecules associated with certain diseases, which lead to diagnosis and/or treatment at an earlier stage.

The microchip system in question has a tiny sieve structure built into it. This enables it  to sort through continuous streams of biological fluids and accurately separate proteins according to their size. The most common separation methods utilize other elements such as gels, which only slow the process down in the end. This system could bring sorting times down from hours to a matter of minutes.
