摘要

摘要

En 中文
The oblique-incidence reflectivity difference (OI-RD) scanning microscopy has the capability of simultaneously measuring binding curves of a protein probe with tens of thousands molecular targets in a microarray and yielding reaction rate constants. However, the quality of reaction rate constants is influenced by the fluidic system. To improve the quality of reaction rate constant measurement over the entire microarray, we demonstrate a fluidic chamber that allows the fluid to flow from the bottom to the top uniformly across the microarray and thus provides more uniform and accurate measurements of reaction rate constants with simplified fluidic design.
