Rice University’s Center for Biological and Environmental Nanotechnology (CBEN) researchers have developed a quantum dot that is programmed to light up only when activated by specific proteases.
Altered expression of particular proteases is a common hallmark of cancer, atherosclerosis, and many other diseases.
The probe’s design makes use of a technique called “quenching” that involves tethering a gold nanoparticle to the quantum dot to inhibit luminescence. The tether,… read more
