“…Therefore, it is essential to develop simple, sensitive and accurate analytical methods for 4-AP detection in pharmaceutical preparations. Since 4-AP is an electroactive compound, considerable interests have been focused on the development of chemically modified electrodes for 4-AP detection [25][26][27][28][29][30].…”

An electrochemical sensor based on graphene-polyaniline (GR-PANI) nanocomposite for voltammetric determination of 4-aminophenol (4-AP) is presented. The electrochemical behavior of 4-AP at the GR-PANI composite film modified glassy carbon electrode (GCE) was investigated by cyclic voltammetry. 4-AP exhibits enhanced voltammetric response at GR-PANI modified GCE. This electrochemical sensor shows a favorable analytical performance for 4-AP detection with a detection limit of 6.5 × 10 −8 M and high sensitivity of 604.2 A mM −1. Moreover, 4-AP and paracetamol can be detected simultaneously without interference of each other in a large dynamic range.

In this study, a miniaturized high fundamental frequency quartz crystal microbalance (QCM) is fabricated for sensor applications using a wet etching technique. The vibration area is reduced in the fabrication of the high frequency QCM with an inverted mesa structure. To reduce the complexity of the side wall profile that results from anisotropic quartz etching, a rectangular vibration area is used instead of the conventional circular structure. QCMs with high Q values exceeding 25,000 at 47 MHz, 27,000 at 60 MHz, 24,000 at 73 MHz and 25,000 at 84 MHz are fabricated on 4 × 4 mm2 chips with small vibration areas of 1.2 × 1.4 mm2. A PMMA-based flow cell is designed and manufactured to characterize the behavior of the fabricated QCM chip in a liquid. Q values as high as 1,006 at 47 MHz, 904 at 62 MHz, 867 at 71 MHz and 747 at 84 MHz are obtained when one side of the chip is exposed to pure water. These results show that fabricated QCM chips can be used for bio- and chemical sensor applications in liquids.

“…Additionally, traditional Resorcinol‐Formaldehyde (RF) carbon aerogels & Phenol‐Formaldehyde (PF) carbon aerogels are mostly non‐flexible brittle solids, with difficult to control microstructures. The monomer resorcinol is also a costly reagent, and its reaction with formaldehyde is tough to control owing to the higher activity for the two hydroxyl (‐OH) groups connected to the benzene ring, making it cumbersome for large scale commercial production …”

Biomass-derived carbon aerogels refer to carbon aerogels prepared using biomass as the precursor. They are environmentally friendly, cheap and have abundant precursors, which have aroused widespread interest and exhibit excellent performance in the fields of electrocatalysis (e. g. for the hydrogen evolution, oxygen evolution and oxygen reduction reactions) and energy storage (i. e. as electrode materials for supercapacitors). Furthermore, metal species can be incorporated into the porous carbon matrix without destroying the original 3D structure whilst improving its conductivity and electro-chemical performance. Above all, most biomass materials contain nitrogen functionalities, and can be doped in situ (selfdoping) with heteroatoms, such as N, without any additives, thereby creating additional defects and active centers with augmented electron density and electron-contributing attributes. Herein, the electrochemical applications of biomassderived carbon aerogels reported during the last decade, especially in the field of water electrolysis, metal-air batteries, fuel cells and supercapacitors, are summarized. Current research challenges and future directions are briefly highlighted.
