IMMUNE BIOSENSORS FOR DIAGNOSTICS AND CONTROL OF SALMONELLA TYPHIMURIUM
Abstract
Several types of biosensors based on optical (SPR, TIRE), potentiometric (ISFET) transducers and one based on ZnOnanorods are proposed for S. typhimurium detection. An effect of preliminary preparation of transducers to the sensitivity of analysis was analyzed. It was found that all proposed biosensors were effective for S. typhimurium detection in model solutions and can be used in practice at different levels of diagnostics. The highest sensitivity was obtained using TIRE based biosensor that was several cells (less than 5) in 10 ml.
