The achievement of an efficient acoustic biosensor based on one dimensional solid-liquid phononic crystals supporting bound states in the continuum (BICs) and Fano resonances is reported herein. The structure used in this work is made of solid-liquid-solid triple layer embedded in water. The main results in this paper consist to study the impact of: i) the effect of albumin concentration, ii) the effect of the albumin layer thickness and iii) the influence of the incidence angle θ on albumin detection performance.
