Microfluidic multiplexed partitioning enables flexible and effective utilization of magnetic sensor arrays

Lab Chip. 2015 Nov 21;15(22):4273-6. doi: 10.1039/c5lc00953g.


We demonstrate microfluidic partitioning of a giant magnetoresistive sensor array into individually addressable compartments that enhances its effective use. Using different samples and reagents in each compartment enables measuring of cross-reactive species and wide dynamic ranges on a single chip. This compartmentalization technique motivates the employment of high density sensor arrays for highly parallelized measurements in lab-on-a-chip devices.
