“…LODs of 0.3, 0.9, and 0.4 µM were obtained for DA, AA, and UA, respectively, using the N-MWCNT/AuNPs electrode in a CV experiment. These LODs are lower compared to the values reported by Wang et al [144] Every electrode modification aims to arrive at a better sensing platform. Specifically, the incorporation of MIPs in CNTs matrix for the detection of NTs aim to benefit from the specificity of MIPs and the proven high conductivity of CNTs.…”

“…A strategy involving the use of a reactive polymer in a MWCNTs containing matrix for DA and UA determination in the presence of interfering AA was made available by Wang et al (2016). [144] The design of the modified working electrode was centered on the fact that a more porous, conducting and chemically stable platform can be actualized through the formation of a conducting polymer, graphene (GR) and CNTs hybrid. A suspension composed of graphene and polydopamine (Pdop) was dispersed in MWCNTs to form a dispersion subsequently cast on GCE.…”

Neurotransmitters (NTs) are chemical compounds that play an important physiological role in the functioning of central nervous, renal, hormonal, and cardiovascular systems. Their function is to regulate neural interactions by reducing the permeability of gap junctions between adjacent neurons of the same type. The abnormal level may lead to diseases, such as Parkinson's disease, Huntington's disease, Alzheimer's diseases, and other neurological diseases. The devastating health hazards associated with the abnormal presence of NTs in biological systems coupled with the demerits of most modern detection methods necessitates the continuous development of novel electrochemical sensors. Carbon nanotube (CNT)-based sensors, as a result of the large surface area, biocompatibility, and chemical stability supplied by CNTs, have proven to offer massive sensitivity and low limit of detection (LOD). Its significance in sensors applications toward the detection of different group of compounds cannot be overemphasized. There are several review articles on NTs and their determination using different chemically modified electrodes and sensor platform. However, this review highlights the significance of notable NTs and the progress made in the last decade in the design of CNT-based sensors for the detection of common NTs.

“…For AD detection, Shin et al [ 41 ] proposed a biosensor for the detection of DA, a neurotransmitter responsible for memory, behavior and movement. By using an ITO working electrode modified with GO and AgNPs ( Figure 14 A), they achieved a lower LOD compared to previous works that employed gold or carbon-based nanomaterials [ 162 , 163 ], improving biosensing performance at low DA levels. The electrochemical detection of DA was performed by direct detection of the oxidation process of this molecule by CV, DPV and amperometry.…”

Alzheimer’s disease (AD) is an untreatable neurodegenerative disease that initially manifests as difficulty to remember recent events and gradually progresses to cognitive impairment. The incidence of AD is growing yearly as life expectancy increases, thus early detection is essential to ensure a better quality of life for diagnosed patients. To reach that purpose, electrochemical biosensing has emerged as a cost-effective alternative to traditional diagnostic techniques, due to its high sensitivity and selectivity. Of special relevance is the incorporation of nanomaterials in biosensors, as they contribute to enhance electron transfer while promoting the immobilization of biological recognition elements. Moreover, nanomaterials have also been employed as labels, due to their unique electroactive and electrocatalytic properties. The aim of this review is to add value in the advances achieved in the detection of AD biomarkers, the strategies followed for the incorporation of nanomaterials and its effect in biosensors performance.

“…In addition, the graphene‐based sensors have been combined with other organic, inorganic, and hybrid components. The organic components such as fullerene, [ 76 ] multi MWCNTs, [ 80 ] and GQDs [ 81 ] increase the surface area and the electrochemical conductivity of the sensors, resulting in lower detection limits of biomarkers such as dopamine. Nitrogen doping through the thermal treatment of rGO with p‐phenylamine has also been reported to boost the sensors’ electrochemical properties.…”

Graphene‐based materials (GBMs) demonstrate unique electrochemical, mechanical, thermal, and optical properties rendering them attractive candidates for numerous biomedical applications. Since graphene's discovery, GBMs have been at the forefront of biomedical research offering innovative solutions for numerous diseases, including neurodegenerative disorders (NDs). There are numerous reviews in which synthesis and functionalization methods of GBMs are discussed. However, this review focuses specifically on the recent research advances of GBMs for NDs, and more specifically, on sensing and therapeutic applications. After a short description of NDs’ main characteristics, significant attention is given to the functionalization strategies used to improve the biomedical properties of GBMs, and recent applications for Alzheimer's disease, Parkinson's disease, Huntington's disease, multiple sclerosis, and amyotrophic lateral sclerosis. A description of the use of GBMs and neural stem cell technology and known toxicity issues, followed by several limitations that current GBMs need to overcome, completes this review.
