Metamaterial Microwave Biosensor Based on CSRR for Monitoring of Leukemia Blood Cancer

Detecting and diagnosing cancer poses considerable challenges in contemporary healthcare. Consequently, this study proposes an innovative biosensor designed for the detection of cancer cells using a complementary square ring resonator (CSRR). The resonator is modeled to achieve high sensitivity and selectivity in cancer detection. through the distinctive characteris-tics of the metamaterial structure in the GHz range, the resonator enhances the interaction of electromagnetic waves with a simple under test. Through simulations, we illustrate the resonator's accurate cancer detection capabilities. The sensitivity, estimated at 0.105 GHz/RIU, and the quality factor in free space, approxi-mates 22.81. The simulations validate that this biosensor exhibits remarkable frequency shifts, compact electrical dimensions, and high sensitivity. The proposed configurations demonstrate the biosensor's potential for detecting leukemia cancer cells in blood.
