Electrochemical reduction and determination of Cibacron Blue F3GA at poly-l-lysine modified glassy carbon electrode

Poly(glutamic acid) nanofibre modified glassy carbon electrode: Characterization by atomic force microscopy, voltammetry and electrochemical impedance

“…[1][2][3][4][5][6][7][8][9][10], polyalanine [11], polyglycine [12,13], poly(glutamic acid) [14][15][16][17][18], polyhystidine [19][20][21][22], polycysteine [23][24][25], polytyrosine [26] and polytryptofane [27,28]. Together with their ease of preparation, good stability, reproducibility, they show improved selectivity and sensitivity in electroanalytical measurements.…”

Fe(CN)$\rm{ {_{6}^{4-}}}$‐Doped‐Glutaraldehyde‐Cross‐Linked Poly‐L‐Lysine Film Electrode. Part 1: Electrochemical Characterization and Its Electrocatalytic Activity Towards Oxidation of Ascorbic Acid

“…A film composition of 97.5% PLL: 2.5% GA produces stronger adhesion to the electrode surface without significantly affecting the high anion exchange capacity of PLL coating. These authors have utilized the glutaraldehyde-cross-linked PLL film (PLL-GA) coated electrodes as voltammetric sensor for the determination of iodide and idoxuride [32], notroprusside [33,34], and Cibacron blue F3GA dye [35] based on pre-concentration approach. Thus, the present procedure, as an improvement over PLL coating, provides new approach to prepare modified electrodes for sensor applications.…”

Electrodeposited indigotetrasulfonate film onto glutaraldehyde-cross-linked poly-l-lysine modified glassy carbon electrode for detection of dissolved oxygen

“…Also, PLL can be used as cationic polyaminoacid (pK a = 10.4) and used for anion detection [3][4][5][6][7][8][9]. Due to its versatility and easiness to preparation, PLL have been used recently for modification of several types of electrodes (glassy carbon, pyrolytic graphite, platinum, gold) and applied for electrochemical determination of biological molecules, pharmaceutical compounds, dyes and metals [5][6][7][8][9]. Glutaraldehyde is an aliphatic dialdehyde whose major uses are based on its highly reactive chemical properties.…”
