Figure 4From: Systems biology coupled with label-free high-throughput detection as a novel approach for diagnosis of chronic obstructive pulmonary disease A schematic representation demonstrating how a COPD-specific SPR microarray chip could be employed. A small blood sample would be required, which would be separated into serum and cellular components using a microfluidic approach. Varying gene and protein expression would be monitored by changes in SPR enabling label free detection.Back to article page
