Boronic acid-functionalized magnetic nanocomposites for an efficient extraction of dopamine molecules and their detection using fluorescent polydopamine

Drug-induced dyskinesia is caused by dopamine receptor blockers, drugs prescribed for treatment such as depression and insomnia in clinical practice. It is necessary to have a reliable and facile technique which can quantify the dopamine concentration in real time. We have prepared boronic acid-functionalized magnetic nanocomposites which can capture plasma dopamine and its detection using fluorescent polydopamine.
