Continuously Sorting Particles According to Shape

by Hector Munoz in Microfluidic Future

There are numerous filters to separate particles in liquid based on their size, which can be enough to isolate them; however, particle shape can be more important, as it distinguishes healthy red blood cells from those affected by sickle-cell disease or malaria. Shape can also be used to determine what stage a cell is in of the cell cycle, which would benefit researchers looking for dividing cells. Recent research by Dino Di Carlo of UCLA looks to separate particles of differing aspect ratios co........ Read more »

What it feels like for a sperm

by aatishb in Empirical Zeal

We don’t usually learn about the physics of squishy things. Physics textbooks are filled with solid objects such as incompressible blocks, inclined planes and inelastic strings. This is the rigid world that obeys Newton’s laws. Here, squishiness is an exception and drag is routinely ignored... Continue reading →... Read more »

Blood: Clot, Flow and Slip

by Arunn in nOnoScience (a.k.a. Unruled Notebook)

By 2020 seventy percent of the heart patients of the World, a study suggests, would be in India. The cause seems genetic. The gene that codes the enzyme called PON1 is defective in Indians and predisposes them to heart ailments and diabetes. Coupled with degenerating lifestyle – eating habits – leads to such a dire [...]... Read more »
