Analytical chemistry is the science of qualitative and quantitative analysis, which is employed in many fields: pharmaceutical industry, medical research, and food science. These are only a few examples in which analytical techniques are required. A reliable, precise measurement is dependent on an accurate, sensitive and robust method as well as the nature and complexity of the matrices analyzed and the concentration and stability of the analyte. This book describes how new materials are applied to improve the sensitivity of analytical platforms and diagnostic tests. Hydrogel nanoparticles...
