“…Moreover, compared with the FT-IR spectrum of non-modified α-Al 2 O 3 , the FT-IR spectrum of PDA-modified α-Al 2 O 3 contains remarkable bands at 1058, 1274, 1510, 2938 cm À 1 , which match well with the FTIR spectrum of PDA [46,47]. The band at 1058 cm À 1 can be assigned to C-O stretching vibrations of carbonyl groups, and the band at 1274 cm À 1 indicates C-OH stretching vibrations [48,49]. The band shown at 1510 cm À 1 is related to N-H vibration.…”

“…The characteristic strong absorption specific peak at 228 nm correspondence to the π → π* transition of aromatic C=C; and in addition, the shoulder peak at about 300 nm can be assigned to n – π* transition of aromatic C=O bonds in scanned UV–Vis absorbance in Figure . After self‐polymerization of dopamine and reducing of graphene oxide in pH = 8.5, the absorbance peak at 228 nm shifted to 280 nm, indicating the reduction of graphene oxide with electronic conjugation dopamine …”

The Glucose amount of human blood is very vital because in higher levels than allowed value the corporal biological system was hampered. Therefore, in this study, the Cu 2 O was deposited on the reduced Graphene oxide (RGO) by polydopamin (PDA) as linker. The new RGO-PDA-Cu 2 O nanocomposite was deposited on the glassy carbon electrode (GCE) surface after its characterization by UV-Visible, fourier transform infrared (FT-IR), X-ray diffraction (XRD), Energy-dispersive X-ray (EDX), transmission electron microscopy (TEM) and field emission scanning electron microscopy (FESEM) techniques. The electroanalysis of the new electrode was investigated by the cyclic voltammetry (CV), differential pulse voltammetry (DPV) and electrochemical impedance spectroscopy (EIS) methods. The obtained detection limit of glucose (Glu) showed that the deposited GCE by RGO-PDA-Cu 2 O nanocomposite has a high potential for its diagnosis. In addition, this electrode was applied to the Glu detection as biosensor in real samples in order to utilize in commercial applications.

“…PDA also serves as a functional material for incorporating the various functional groups such as catechol, amine, and imine 19 20 . PDA can be easily incorporated within GO or RGO as a functional nanomaterial in wide range of biomolecular and electrochemical sensor applications 21 22 23 . Chlorpromazine (CPZ) is well-known antipsychotic drug, widely used in the treatment of schizophrenia, bipolar disorder and mania 24 25 .…”

“…To date, only a limited number of papers have focused on RGO@PDA composite for electrochemical sensor applications and all reported techniques for the fabrication of PDA incorporated RGO have done so by chemical methods 22 23 . In the present study, we have fabricated an RGO@PDA composite by a simple electrochemical method for the first time and utilized it as an advanced electrocatalyst for the oxidation of CPZ.…”

We report a novel and sensitive amperometric sensor for chlorpromazine (CPZ) based on reduced graphene oxide (RGO) and polydopamine (PDA) composite modified glassy carbon electrode. The RGO@PDA composite was prepared by electrochemical reduction of graphene oxide (GO) with PDA. The RGO@PDA composite modified electrode shows an excellent electro-oxidation behavior to CPZ when compared with other modified electrodes such as GO, RGO and GO@PDA. Amperometric i-t method was used for the determination of CPZ. Amperometry result shows that the RGO@PDA composite detects CPZ in a linear range from 0.03 to 967.6 μM. The sensor exhibits a low detection limit of 0.0018 μM with the analytical sensitivity of 3.63 ± 0.3 μAμM–1 cm–2. The RGO@PDA composite shows its high selectivity towards CPZ in the presence of potentially interfering drugs such as metronidazole, phenobarbital, chlorpheniramine maleate, pyridoxine and riboflavin. In addition, the fabricated RGO@PDA modified electrode showed an appropriate recovery towards CPZ in the pharmaceutical tablets.
