WebJun 22, 2024 · Serum levels of immunoglobulins are on the order of hundreds of mg/dl, which could well have optical effects. The antibody diversity may on the other hand be up to $10^ {18}$, making detecting the presence of a few antibody strains among the rest infeasible. So maybe a signal-to-noise argument could make the no a bit firmer. WebHowever, selecting the working fluid with blood density and viscosity, and PDMS index of refraction (RI) for such experiments is challenging. Currently, water–glycerol is commonly used and sodium iodide (NaI) is often added to increase the index of refraction without changing fluid viscosity. But the resulting fluid density is well above blood.
