Biosensors technology for anti-epileptic drugs.

A broad group of antiepileptic drugs (AEDs) often controls the frequency of seizures. Given the variability of pharmacokinetics, narrow target range, and the difficulty of identifying signs of toxicity from laboratory responses, therapeutic monitoring of AEDs plays a vital role in optimizing drug administration. Nanomaterials, especially biosensor-based methods, can facilitate the analysis of these agents with unique advantages such as rapid analysis, sensitivity, selectivity, and low cost. This review describes recent advances in biosensors developed to analyze AEDs. First, we described common electrochemical measurement techniques and types of deposited electrode substrates. Additionally, various chemical and biological modifiers to improve the sensitivity and selectivity of the sensor have been categorized and briefly described. Finally, the prospects for developing an electrochemical platform for quantifying AEDs are presented.
