Small Particles (Things) Matter!- Introducing Nanoparticle PCR

There are many different methods and protocols on making your PCR  run more efficiently. I recently came across an interesting PCR method called “nanoparticle” PCR. This method seems to attract a lot of attention, because it enhances a PCR  by a few orders of magnitude. More interestingly, while the enhancement effect has been reported in a…

Hydrodynamic Focusing in Flow Cytometry

If you have sorted samples or phenotyped cells by surface expression of proteins, you’ve probably wondered how each cell is sorted or phenotyped in a flow cytometer? This question seems trivial, but in reality it took a while for engineers to figure it out. Before I get into today’s topic on “hydrodynamic focusing,” I’ll walk…
