Acoustic biosensors are widely used in physical, chemical, and biosensing applications.One fr3603 of the major concerns in acoustic biosensing is the delicacy of the medium through which acoustic waves propagate and reach acoustic sensors.Even a small airgap diminishes acoustic signal strengths due to high acoustic impedance mismatch.Therefore, the presence of a coupling medium to create a pathway for an efficient propagation of acoustic waves is essential.Here, we have reviewed the chemical, nautica voyage hajuvesi physical, and acoustic characteristics of various coupling material (liquid, gel-based, semi-dry, and dry) and present a guide to determine a suitable application-specific coupling medium.
