(PhysOrg.com) -- When trying to understand how cells respond to toxins, scientists want to do as little sample preparation as possible. Preparing these cells by immersing them in chemicals or drying them out can erase vital information. At Pacific Northwest National Laboratory, scientists  proved that a new ionization technique they developed in 2009 can provide fingerprint and locate proteins, amino acids, and other chemicals in cells that make up tissues or microbial communities using mass spectrometry.
