 Sometimes
innovation really is accompanied by a sudden flash of light, as experienced
by Ulrich B. Wiesner, Materials Science and Engineering, and Hooisweng
Ow, one of Wiesner's Ph.D. students. They created a new, nanoscale
fluorescent bead. The novel fluorescent beads, referred to as CU
Dot fluorescent nanoparticles or CU Dots, for short, are comparable
to the much-hyped quantum dots in brightness and size, but lack their
toxicity. Therefore, CU Dots can easily be used in the life sciences,
for example, to track the motion of proteins on cell surfaces or
to visualize biological entities (bioimaging) as in the labs of Barbara
A. Baird, Chemistry and Chemical Biology; Nanobiotechnology Center.
