Label-free Optical Detection of Viruses and NanoparticlesIn his thesis, the author explored optical methods to detect, quantify and characterize nanoparticles and viruses < 100 nm in size on a single particle basis, label free and in real time. The methods are based on optical interferometry, where the signal obtained from a single nanoparticle is proportional to the amplitude of the light scattered from the particle, rather than intensity. This results in weaker size dependence of the signal than for a

In his thesis, the author explored optical methods to detect, quantify and characterize nanoparticles and viruses < 100 nm in size on a single particle basis, label-free and in real-time. The methods are based on optical interferometry, where the signal obtained from a single nanoparticle is proportional to the amplitude of the light scattered from the particle, rather than intensity. This results in weaker size dependence of the signal than for a technique that measures light scattering intensity, and therefore enables detection of smaller particles.

Not so much
Size: Small (Pack of 1)
My Pup likes other chew bone from this company, but not so much this shape. *As with all these type THROW them away when they become too chewed up*! Pieces of nylon aren't meant to be eaten..

Love it
Size: Small (Pack of 1)
We adopted our pup and the only thing that came with her was this toy. She loves it!!! Of course we have to purchase a new one about every 3 months, when the plastic starts crumbling.
