Congratulations to Mr. Xiaole Mao (Bioengineering), Mr. John Waldeisen (B.S., E Sc, 2007), and Dr. Tony Huang (the James Henderson Assistant Professor and assistant professor of engineering science and mechanics). Their scientific graphic titled "3D Hydrodynamic Focusing Process" was selected as the cover design for the October 2007 issue (Volume 7, Number 10) of the journal Lab on a Chip. The graphic was created for their paper titled "Microfluidic drifting--implementing three-dimensional hydrodynamic focusing with a single-layer planar microfluidic device," which appears on pages 1260-1262 of the publication.
