عنوان انگلیسی A Sensitive Novel Approach towards the Detection of 8-Hydroxyquinoline at Anionic Surfactant Modified Carbon Nanotube Based Biosensor: A Voltammetric Study
چکیده انگلیسی مقاله A rapid electrochemical technique was developed to determine 8-Hydroxyquinoline (8HQ). In the current study, the anionic surfactant Sodium lauryl sulfate (SLS) was immobilized on the multi-walled carbon nanotube (MWCNT) paste surface for the fabrication of electrode to detect 8HQ in phosphate buffer solution (PBS) of pH 7.0. The response of SLS modified carbon nanotube paste electrode (SLSMCNTPE) was inspected via cyclic voltammetry (CV), and it exhibited a quasi-reversible, diffusion-controlled electrode process for 8HQ. Field Emission Scanning Electron Microscopy (FESEM) was adapted to exemplify the electrode surface. The experimental parameters inclusive of variation in pH and scan rate were optimized. This currently prepared sensor displayed excellent stability, reproducibility, repeatability along with elevated sensitivity in CV with the limit of detection (LOD) 1.1×10-7 M and limit of quantification (LOQ) 3.9×10-7 M. Because of the ease of preparation and regeneration of the developed sensor extended new prospect for rapid, and sensitive analysis of 8HQ
