Could an inductive sensor help assay biological and other substances?

A left-handed (LH) antenna based biosensor is developed to investigate the near-field electromagnetic interaction between antenna and sample with different dielectric properties. These dielectric properties can be determined by analyzing the electromagnetic coupling between the antenna and the test samples without labeling or chemical reaction. It has the advantages of real-time detection, small feature size, reduced sample volume, and minor environmental disturbance. Such an antenna sensor can be effectively used to measure both liquid and solid biological samples.
