Electrochemistry belongs to an important branch of chemistry that deals with the chemical changes produced by electricity and the production of electricity by chemical changes. Therefore, it can not only act a powerful tool for materials synthesis, but also offer an effective platform for sensing and catalysis. As extraordinary zero-dimensional materials, carbon-based quantum dots (CQDs) have been attracting tremendous attention due to their excellent properties such as good chemical stability, environmental friendliness, nontoxicity and abundant resources. Compared with the traditional methods for the preparation of CQDs, electrochemical (EC) methods offer advantages of simple instrumentation, mild reaction conditions, low cost and mass production. In return, CQDs could provide cost-effective, environmentally friendly, biocompatible, stable and easilyfunctionalizable probes, modifiers and catalysts for EC sensing. However, no specific review has been presented to systematically summarize both aspects until now. In this review, the EC preparation methods of CQDs are critically discussed focusing on CQDs. We further emphasize the applications of CQDs in EC sensors, electrocatalysis, biofuel cells and EC flexible devices. This review will further the experimental and theoretical understanding of the challenges and future prospective in this field, open new directions on exploring new advanced CQDs in EC to meet the high demands in diverse applications.[a] Dr.

Carbon Nanodots in Electrochemical Sensors and Biosensors: A Review

et al. 2020

View full text Add to dashboard Cite

This Review presents the latest advances in designing electrochemical sensors by using carbon nanodots (CNDs), carbon dots (CDs), and graphene quantum dots (GQDs), as a new class of photoluminescent nanomaterials, which can be employed in a vast number applications, such as biomedicine, biosensing, optical sensing, catalysis, solar cells, imaging, and electrochemical sensing. Recently, the application of CDs and GQDs in electrochemical sensing has increased significantly because of their unique features such as quantum size, excellent biocompatibility, enzyme‐like activity, high active area, and abundance of hydrophilic groups, such as hydroxyl, carboxyl, or amine functionalities. The applications of CDs and GQDs for the electrochemical sensing of hydrogen peroxide, glucose, other organic molecules, as well as metal ions are presented. The utilization of CDs and GQDs for immunosensing and aptasensing is also reported.

“…To overcome these shortcomings, vast numbers of materials and functionalization protocols incorporated nanomaterials and polymers have been employed. These materials increased the surface area, conductivity, and resulted in the creation of ultrasensitive “nanofunctionalized sensors” or briefly “nanosensors.” Nanosensors are not only sensitive in detecting biomarkers at low concentrations but they can also identify the change of concentration in the matrices for various applications. This allowed quantitative screening of recovery from traumatic brain injuries and concussions, monitoring of cancer progression or regression in response to therapeutics, rapid detection of blood infection and sepsis, and managing the performance of treatments such as water and food treatment strategies .…”

Electrochemical nanobiosensors are ultrasensitive tools used for detection and monitoring of various markers in biofluids. In the absence of reliable techniques for large‐scale production of reproducible nanomaterial structures on the electrodes, they are created individually in batch‐production. This has become a substantial hurdle in the practical implementation of electrochemical nanobiosensors. An automated microfluidic‐based platform (NanoChip) is presented for reproducible and scalable formation of complex nanomaterial constructs with a defined order of nanocomposites and biomaterials to create ultrasensitive nanobiosensors. The automated liquid handling system of the setup delivers reagents to electrodes inserted temporarily into the chip for modifying their surfaces by depositing different nanomaterials. The NanoChip platform is used for the creation of a multilayer nanocomposite structure on the electrode surface. These reproducible nanobiosensors are used for detecting breast cancer cells in the blood. The nanobiosensors offered a dynamic detection range of 10 to 5 × 106 cells mL−1. Performance of sensors produced from NanoChip shows similar selectivity and operational range along with improved sensitivity and reproducibility compared to sensors developed using batch process. These features make automated Nanochip technology a versatile tool for producing nanosensors for the ultrasensitive detection of various markers in biomedical, clinical, energy, and environmental applications.
