A Science Talk: From the Death of an Icon to the Birth of a Physical Principle for Ultra-sensitive label-free Bio-sensing
The Department of Physics and Astronomy welcomes Stephen
a Professor of Physics and Chemistry at the Polytechnic Institute
of NYU, to present the latest in a series of "Science Talks" open
to the public.
From Professor Stephen Arnold:
The announcement (in 2002) that the death of my favorite
teacher and arguably the worldís most prolific science fact and
fiction writer (Asimov, >500 books) had been from an HIV
infection (contracted during open heart surgery) redirected my
laboratoryís efforts to inventing a means for immediate detection
of the individual virions in blood. Although trials in serum may not
have begun, the physical principle that evolved is likely the most
ubiquitous approach for research in ultra-sensitive label-free
In my lecture I will trace the evolution of the so-called Reactive
Sensing Principle in Micro-cavity frequency shift detection from
its inception in 2003 and discuss how it is connected intimately to
With time permitting I will discuss how Nano-optics, specifically
Plasmonic Enhancement can play an important role in reducing
the detectable mass to the single protein level.
