Immunoassay technique performs a fast, simple, reliable, and sensitive analysis of different compounds, being applied in several areas of interest such as clinical analysis for medical diagnosis, as well as in environmental analysis, and food quality control. The latest research activities in this field are represented by the attempts to achieve a low limit of detection by developing of new signal amplification strategies, eliminate the interferences, and decrease the cost of analysis.
