Photo of the week

This series of photos shows my labmate blasting a solution of tiny nanoparticles with sound waves in a process called sonication. The sound waves are generated at the tip of the probe which is submerged in the solution (top photo). As the sound waves are generated, the solution is displaced/moved (seen in series in the lower two photos). My labmate used this method to break up any clumps of nanoparticles that may have formed. Once evenly dispersed, the solution is added to cultured human cells and the effects observed.
