How to measure polymer brush swelling and collapse

Polymer brushes, polyelectrolyte multilayers and hydrogels are typically used to achieve desirable properties. Key parameters influencing these properties are layer conformation and the degree of hydration. Here we show a straightforward way to measure polymer brush swelling and collapse.

How much protein adsorbs to glass and plastics?

Proteins tend to passively adsorb to surfaces. The amount adsorbed depends on many factors such as the protein itself, the ambient conditions and the surface material. So how can the adsorbed amount at these various conditions be assessed? Here we show how protein adsorption can be quickly measured.
