“…The effectiveness of this approach has been already demonstrated in several areas of medical field such us nucleic acids analysis (Petralia, Cosentino, et al, 2017; Petralia, Sciuto, Di Pietro, et al, 2017; Petralia, Sciuto, et al, 2017) glucose and biomolecules sensing (Petralia et al, 2018) where the electrochemical systems provided a high miniaturization degree and rapid, highly‐sensitive analysis (Petralia & Conoci, 2017). However, they present some drawbacks due to sample preparation introducing additional variability into the measurement (Toor et al, 2015), expensive fabrication costs due to functionalization of electrodes in case of enzyme‐based sensors (Fu et al, 2011; Pujol et al, 2014) and weak specificity for electrochemical sensors based on noble metal nanoparticle‐modified electrodes (Babar et al, 2019; Kumar et al, 2017; Majid et al, 2006; Petralia et al, 2012).…”
