A microfluidic chip that sequentially processes microliter volumes to detect variable concentrations of protein analytes was described. Application of a hydrophilic coating to the separation area of the chip proved to be effective in the reduction of the adsorptive interactions of the target protein with the glass and polydimethylsiloxane (PDMS) surfaces. A linear relationship was observed between the signal intensity and protein concentration over the entire testing range. In the second generation chip, a design that allowed to test multiple samples in parallel was also developed.
