Professors from Princeton worked in collaboration with their friends at the Boston University from Massachusetts to develop a new device that focuses streams of cells in a liquid, and even separate them according to their size.
The discovery can be used to sort out cells from the blood flow that look suspicious, and that could be cancer carriers. The device consists of a silicon wafer studded with rows of tiny pillars through which a liquid containing multi-sized particles is made to flow. The blood will flow slower thorough it, due to friction, and the particles or cells of regular size will get through.
The bigger cells, however, will get stuck in the pillars, so the whole liquid is successfully bolted in the process. There have been many researches done over the years for a cure for cancer, and we only came up with ways to eliminate infected sections of the body or tumors. After doing that, if the doctors weren’t careful enough, a few cells could remain and spread through the body.
This method hasn’t been applied to anything yet, but we’re pretty sure it will soon solve the spreading matter, if the blood going out of the excised area will be filtered after surgery. The teams of researchers from both Princeton and Boston universities should be congratulated for their idea, which should save many lives, at least until doctors will find a cure to definitely prevent cancer.
