Electrochemical Sensor Applications of Nanoparticle Modified Carbon Paste Electrodes to Detect Various Neurotransmitters: A Review

Abstract

Neurotransmitters are synapses transmitting messengers that are vital towards human wellness. Any abnormality in their behaviour can lead to huge psychological ailments such as Parkinson's, Alzheimer's, and Schizophrenia. During diagnosing and assessing mental diseases, it is critical to discover distinct measures of different neurotransmitters present. A combination of nanomaterials, proteins, and polymers are employed to create suitable detecting and sensing component systems. Electrochemical detection has been widely employed for in-vivo detection, with FSCV emerging as the most promising technology to date due to advantages such as high sensitivities, simple device structure, and facile downsizing. Excessive background noise and signal, restricted target selectivity, declination with time, and the device fouling are all issues that in-vivo electrochemical neurotransmitter indications encounter. Nanomaterials have sparked a tremendous focus in recent years owing to their diverse properties. CPEs are amongst the safest and most ecologically beneficial electrodes with a vast scope of applications due to their incredibly simple and rapid manufacturing method, lower back - ground current, relatively inexpensive, adaptability to numerous modifiers and modifying techniques, so on and so forth.

Fabrication of Mechanically Alloyed Super Duplex Stainless Steel Powder-Modified Carbon Paste Electrode for the Determination of Methylene Blue by the Cyclic Voltammetry Technique

“…Limit of detection (LD) and limit of quantification (LQ) of the electrode were determined using the blank voltammogram (c) using eqs 3 and 4 as follows 49…”

Introductory Chapter: Introduction to Aluminum Alloys

“…The purpose of this is that today's technology is competitive in the market and the features of the materials needed are no longer affordable. Above all else, one of the most distinctive features required from materials is to ensure continuity [13][14][15]. In other words, the material produced gives the same physical results and reactions when used at different times but under the same conditions.…”

A Review on Cyclic Voltammetric Investigation of Toxic Heavy Metals

“…Therefore, we need some standard analytical methods to detect the presence of heavy metal ions in foods, plants, animals, water, and soils. Electrochemical methods like cyclic voltammetry [9][10][11][12][13][14][15][16], stripping voltammetry, [4]. differential pulse voltammetry, and polarography are so far best and popular choice to determine the various heavy metals in the environment.…”
