Hyperinvasive locus A gene-based electrochemical nanobiosensor for rapid detection of Salmonella enterica in chicken eggshell matrices

Salmonella enterica can penetrate inside eggshells through horizontal transmission; thus, a rapid detection method on this matrix is needed. This study aimed to develop an electrochemical nanobiosensor prototype based on the hyperinvasive locus A (hilA) gene of Salmonella enterica for rapid (< 8 hrs) detection of the foodborne pathogen in this matrix. The biosensor was characterized in terms of sensitivity, selectivity and linear detection range as well as its capability to rapidly detect...
