Undergraduate Research Team Wins Dean’s Award
Optical Cell Sorting - The Scientist
Congratulations to Ali Aljuraidan (Crown), Aditya Gumparthi (Crown) , Eduardo Hirata (Crown) !! for winning Dean’s Undergraduate Research Award!!
Project Description: Current diagnostic systems require trained personnel, expensive equipment, and a large area, making them infeasible. Our project solves the multi-level problem through automation and miniaturization of components responsible of functionalizing a microfluidic chip. This is done by providing a unified platform capable of functionalization and surface acoustic wave (SAW) particle separation. The platform is capable of completely autonomous operation and requires very little training to operate attributed by its user-friendly interface.

Science AAAS Highlight

… A new wave of label-free methods is offering researchers ways to identify subgroups of cells in live cultures and to home in on the most pertinent populations. Still, many label-free methods rely on only one cell characteristic or are hobbled by their low throughput. To overcome these limitations, researchers are devising tools that rapidly pump high volumes of cells through tiny microfluidic channels etched into a chip and combine the novel use of optics with new image-processing tools.

Novel biosensor technology could allow rapid detection of Ebola virus
by MARK I. STOCKMAN
Measuring minute amounts of chemical and biological objects in the environment and in living organisms is one of the most common and important tasks in chemistry, biology, medicine, environmental monitoring, transportation, homeland security, and defense. Although the existing methods of sensing and detection are numerous and powerful, they are not without shortcomings: insufficient sensitivity; long detection times; necessity for enzymatic, fluorescent, or radioactive labeling; high costs, and so on. Optical spectroscopic methods have the advantage of being fast, noncontact, and relatively inexpensive, but they are not necessarily sensitive enough.

In 2010, Ahmet Ali Yanik published his first paper on the rapid detection of Ebola virus using new biosensor technology he and colleagues at Boston University had invented. But he found there was little interest at the time in developing the technology further.
"People told me that there wasn't any profit in it because this disease only affects people in the developing world," Yanik said.
