Biosensing plays a critical role in biomedical research, environmental monitoring, and clinical diagnostics, providing real-time detection and analysis of biomolecules. Powered by Surface Acoustic Wave (SAW) sensors, it offers unparalleled sensitivity and real-time detection in biomolecule analysis. The Love type Surface Acoustic Wave (LSAW) sensor stands out in fluid biosensing, demonstrating compatibility with microfluidic systems and sensitivity to physical properties due to the influence on surface acoustic wave propagation. Introducing a LSAW-based biosensing platform addresses the demand for sensitive, real-time detection in complex fluidicenvironments and enhance accuracy in biosensing applications. This paper presents a prototype biosensing system that integrates microfluidic techniques with polydimethylsiloxane(PDMS) for fluid circulation. The characterization involved analyzing the sensitivity and stability of the sensor over time using fluids with varying physical properties: distilled water, polyethylene glycol, and sodium chloride solutions. The results demonstrate that the development is on track, and the next step before biosensing would be to accurately differentiate fluid solutions at different concentrations and implement a temperature control to verify if the system performance can befurther optimized.
