Tandem Bubbles with Jet (IMAGE) Duke University Caption The image depicts laser-generated tandem bubbles forming a jet, with arrows overlaid that describe the flow field around the bubbles. A carefully manipulated jetting flow was used to create distinctly different bioeffects (cell death, holes in the membrane, etc.) in individual HeLa cells patterned at varying standoff distances from the bubbles. This fluid dynamic technology might be used to probe single cells in a microfluidic system, with potential applications in diagnosis and treatment.
