“…Recently, there have been a large number of scientific reviews promising not only therapeutic applications of phenolic acids [43,44], but also phenolic compound's effects on the environment and human health risk [25,45]. Furthermore, several authors have investigated varieties of analytical technologies using trace detection of phenolic sub-stances such as electrochemical [39,[46][47][48][49], liquid chromatography with diode array and mass spectrometry [50], high performance liquid chromatography [51,52], conductometric biosensor [53], photoelectrochemical reduction [54], voltammetric detection [55,56], biosensor electrode [57], and nanomaterial-based sensing [58]. However, these methodologies often require additional procedures for separation of analytes in sample preparation, leading to time-consuming and toxic organic solvents, as well as adverse effects on the environment.…”

Many scientists are increasingly interested in on-site detection methods of phenol and its derivatives because these substances have been universally used as a significant raw material in the industrial manufacturing of various chemicals of antimicrobials, anti-inflammatory drugs, antioxidants, and so on. The contamination of phenolic compounds in the natural environment is a toxic response that induces harsh impacts on plants, animals, and human health. This mini-review updates recent developments and trends of novel plasmonic resonance nanomaterials, which are assisted by various optical sensors, including colorimetric, fluorescence, localized surface plasmon resonance (LSPR), and plasmon-enhanced Raman spectroscopy. These advanced and powerful analytical tools exhibit potential application for ultrahigh sensitivity, selectivity, and rapid detection of phenol and its derivatives. In this report, we mainly emphasize the recent progress and novel trends in the optical sensors of phenolic compounds. The applications of Raman technologies based on pure noble metals, hybrid nanomaterials, and metal–organic frameworks (MOFs) are presented, in which the remaining establishments and challenges are discussed and summarized to inspire the future improvement of scientific optical sensors into easy-to-operate effective platforms for the rapid and trace detection of phenol and its derivatives.

This paper reports the preparation of multiwalled carbon nanotubes/4,4′‐dihydroxybiphenyl (MWCNTs‐DHB) nanolayered composite as a new modifier for modification of carbon paste electrode (CPE/MWCNTs‐DHB). CPE/MWCNTs‐DHB shows linear responses for phenol in the concentrations range of 0.04–220 μM with a current sensitivity of 0.67 μA μM−1 and a detection limit of 8.0 nM (S/N=3). The electrode shows high selectivity, good repeatability (RSD=4.1 %), excellent reproducibility (RSD=3.5 %), and acceptable stability (91.2 % over one‐month storage). Moreover, the modified CPE exhibits appreciable recoveries (93.0–104.0 %) indicating its acceptable performance for determination of phenol in tap and river water samples.
