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.

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.

Step In Look Good
Size: 11.5, Color: Cognac Napa Leather
I am wearing these shoes as I write this review, and they look and feel great. I have a bit of a disability with drop foot on the right leg and bilateral neuropathy and have been wearing step in shoes for about 10 years. But the first company that introduced leather dress and casual shoes stopped making them and now only makes sport and casual shoes. So I have been searching for some that meet my need for shoes like this and this company has given me three pairs, so far. Easy to get into, comfortable to wear, and good looking. And they take polish very well, too. (Remember how to do that?). We may buy another pair or two in different styles as well.

Runs tight. Skinny and smaller than other brands.
Size: 8.5, Color: Brown
Comfy and lots of support. Cushiony. Beware: the brown I ordered runs small. Tighter than other brands.
