Non-specific adherence of oxide particles as a means of quantifying protein adsorption on surfaces

This paper reports quantification of a method for measuring amounts of protein adsorbed to a surface; the method is especially useful for revealing macroscopic spatial patterns of adsorption. The experiments tested the effectiveness of iron oxide suspensions adsorbed onto the adsorbed protein to indicate, in separate trials, the amount of either human plasma fibrinogen or human serum albumin (HSA) present on glass slides. Corresponding trials, …
