“…Rhodamine 6G and riboflavin have both been used as analyte molecules in several cases to investigate the optimization of different production of SERS substrates. Furthermore, using the optimized substrates, the detection limit is determined for both analytes [4,23,33,[42][43][44][45].…”

In this study, metallic nanoislands were prepared by thermal annealing of gold thin film produced by vacuum evaporation on a glass substrate to investigate the surface-enhanced Raman scattering (SERS) effect on them. The influence of the analyte on the enhancement factor of SERS was studied with riboflavin and rhodamine 6G dye. Two laser excitation sources at 532 and 633 nm wavelengths were used for SERS measurements. We found that the enhancement factors of the gold nanoisland SERS substrates were influenced by the analytes’ adsorption tendency onto their surfaces. The SERS amplification was also found to be dependent on the electronic structure of the molecules; higher enhancement factors were obtained for rhodamine 6G with 532 nm excitation, while for riboflavin the 633 nm source performed better.

“…Rhodamine 6G and rhodamine B can be detected with SERS in vegetables and contaminants in rain, pond, and tap water [ 224 ]. A sensitive SERS detection of R6G with a linear range of 1 × 10 −9 –1 × 10 −5 mol/L and a detection limit of 1 × 10 −11 mol/L was also realized [ 225 ]. Xu’s team [ 226 ] used SERS signal intensity and chiral signal intensity to detect different concentrations of C. jejuni spiked in milk samples with a good linearity from 1 × 10 2 to 1 × 10 6 cfu/mL.…”

Point-of-care testing (POCT), as a portable and user-friendly technology, can obtain accurate test results immediately at the sampling point. Nowadays, microfluidic paper-based analysis devices (μPads) have attracted the eye of the public and accelerated the development of POCT. A variety of detection methods are combined with μPads to realize precise, rapid and sensitive POCT. This article mainly introduced the development of electrochemistry and optical detection methods on μPads for POCT and their applications on disease analysis, environmental monitoring and food control in the past 5 years. Finally, the challenges and future development prospects of μPads for POCT were discussed.

“…Combining nanostructured materials, as an effective plasmonic resonance phenomenon, with Raman spectroscopy is becoming a potential analytic tool for trace detection of analyte molecules with many advantages such as easy-to-use, low-cost, specific targets, and on-site detection. Specific studies on the development of several novel nanomaterials have been reported to assist effective Raman platforms including nanogold film-based Raman detection of rhodamine 6G and p-nitrophenol [28], Raman detection of multiple analytes based on Ag nanoparticle-modified SiO 2 nanofibrous [29], Ag nanostructure-assisted Raman sensing for monofluoroacetic acid [30], Ag nanoparticle-introduced Raman detection of carbofuran [31], on-site Raman detection of 1,2,3-benzotriazole on colloidal lignin particles [32], Ag-capped silicon nanopillar-based Raman detection of ochratoxin A [33], nano-shell composite array-based Raman sensor for antioxidant [34], and bimetallic plasmonic nanoparticle-assisted Raman detection of hazardous contamination [35]. Moreover, a series of scientific reports on several special metal-organic framework (MOF) structures has been investigated, leading to successful fabrication of novel Raman substrates applied in trace detection of phenol red [36], phenol-soluble modulin [37], and engine oil [38].…”

“…In addition, 2,6-DCP-one of the most significant chlorophenol compounds-has been widely applied in industrial manufacturing for several chemicals, medical compounds, and other products, despite being potentially carcinogenic [42]. Recently, organic compounds with high toxicity such as p-nitrophenol have been found to cause increasingly serious pollution in environmental water [28]. As bisphenol substances have been considered as having a serious impact on the environment and human health risks, the early monitoring of these compounds is not only significant, but also still has many challenges.…”

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.
