A planar dielectric waveguide based structure for bio-sensing purpose is introduced. The proposed device is a silicon-based WGM disc resonator operating within the range of 75-110 GHz (W-band). The sensor is an integrated, miniaturized, low-cost, and easy-to-fabricate bio-sensor structure. The proposed sensor can be used for a number of DNA characterization tasks including Mutation in DNA oligonucleotide. Two types of DNAs, single strand and double strand DNAs, are successfully tested by our integrated sensor. The measurement repeatability and selectivity of the proposed sensor are examined through the different experimental lab-tests.
