“…In addition, it can be concluded that the HNC-Rh-(ImS3-14) sensor presents good sensitivity and a low limit of detection in comparison to results recently published for similar studies ( Table 2). Given the fact that the sensor preparation is fast, easy and yields good analytical parameters, this represents a suitable method for paracetamol determination [25][26][27][28][29][30][31][32].…”

Reagents and solutions All reagents, that is, paracetamol, starch, cellulose, chloroform, RhCl 2 , sodium acetate, sodium phosphate, acetic acid, phosphoric acid and sodium hydroxide, were analytical grade (Sigma-Aldrich) and used without further purification. The halloysite nanoclay was purchased from Sigma-Aldrich and contained nanotubes with 30-70nm of diameter and 1-3µm of length. All solutions were prepared in ultrapure water obtained from a Milli-Q System (Millipore, USA) with a resistivity of 18.2MΩ cm-1. The Rh-(ImS3-14) reverse micelle solution was synthesized according to a procedure previously described in the literature [19]. The paracetamol tablets were purchased at a local drugstore.

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.

A glassy carbon electrode based on graphene quantum dots (GQDs) for simultaneous detection of acetaminophen and ascorbic acid

Abstract: In this present work, graphene quantum dots (GQDs) were handily prepared with citric acid by the pyrolysis method and used to fabricate an electrochemical sensor for the simultaneous determination of acetaminophen (AC) and ascorbic acid (AA) in compound preparation.
