Profiling of protein biomarkers is powerful for the analysis of complex proteomes altered during the progression of diseases. Lab-on-a-chip technologies can potentially provide the throughput and efficiency required for point-of-care and clinical applications. While initial studies utilized 1D microchip separation techniques, researchers have recently developed novel 2D microchip separation platforms with the ability to profile thousands of proteins more effectively. Despite advancements in lab-on-a-chip technologies, very few reports have demonstrated a point-of-care microchip-based profiling of proteins. In this review, recent progress in 1D and 2D microchip profiling of protein mixtures of a biological sample with potential point-of-care applications are discussed. A selection of recent microchip immunoassay-based techniques is also highlighted.
