“…After that, the mixture was centrifuged for 10 min followed by collection of the black precipitate that aggregated in the bottom of the test‐tube. According to Salzmann's protocol CNOs ox were purified [52]. The CNOs ox were stirred in 3.0 M NaOH and rinsed several times using Milli‐Q water until a final pH of 7 was reached, then the samples were dried overnight at 110 °C (Scheme 1B).…”

Glassy carbon electrode (GCE) were modified with nanocomposites containing conductive polyaniline nanotubes (PANInt) and carbon nano‐onions (CNOs). Herein we report a simple and sensitive way for daidzein (DA) determination at concentrations between 1 and 10 μM by linear sweep voltammetry using GCE/PANInt/CNOs system. The DA electrochemical behavior was examined in two buffer environments (pH 7.5 and 4.5) using electrodes modified with the oxidized CNOs or their derivatives containing carboxyl and benzylamino functional groups. The direct electrooxidation of DA was observed at +0.65 V and +0.8 V at pH 7.5 and at +0.7 V and +1.1 V vs. Ag/AgCl at pH 4.5.

“…As a critical component in an electrochemical system, electrodes produce electric signal outputs by interacting with the targeted analytes. Recently, nanomaterials have inched their way into the design and fabrication of electrodes to improve electrochemical responses, due to large surface area (e.g., various nanosheets [ 27–33 ] ) and superior electrochemical properties (e.g., carbon nanotubes [ 40–43 ] and silicon nanowires [ 44–47 ] ). Typically, the nanomaterial‐based electrodes for metabolic analysis can be subclassified into three types according to the material functions, including (1) facilitating enzymatic reactions of the original electrodes; (2) serving as nanozymes with enhanced catalytic activities for replacing natural enzymes; and (3) acting as substrates of non‐enzymatic electrodes with direct electrocatalytic oxidation and good stability.…”

In vitro diagnostics (IVD) has played an indispensable role in healthcare system by providing necessary information to indicate disease condition and guide therapeutic decision. Metabolic analysis can be the primary choice to facilitate the IVD since it characterizes the downstream metabolites and offers real‐time feedback of the human body. Nanomaterials with well‐designed composition and nanostructure have been developed for the construction of high‐performance detection platforms toward metabolic analysis. Herein, we summarize the recent progress of nanomaterials‐assisted metabolic analysis and the related applications in IVD. We first introduce the important role that nanomaterials play in metabolic analysis when coupled with different detection platforms, including electrochemical sensors, optical spectrometry, and mass spectrometry. We further highlight the nanomaterials‐assisted metabolic analysis toward IVD applications, from the perspectives of both the targeted biomarker quantitation and untargeted fingerprint extraction. This review provides fundamental insights into the function of nanomaterials in metabolic analysis, thus facilitating the design of next‐generation diagnostic devices in clinical practice.

“…The papers of electrochemical sensors for detecting puerarin are abundant. Jing et al [ 33 ] proposed a method to synthesize the nanocomposite of graphene, poly(sodium 4-styrenesulfonate) (PSS), and WO 3 nanorods for the sensitive detection of puerarin with satisfactory consequences. A similar assay using the graphene-based sensors directed toward puerarin was shown superior stability and recovery in real samples [ 34 ].…”

Flavonoids have a variety of physiological activities such as anti-free radicals, regulating hormone levels, antibacterial factors, and anti-cancer factors, which are widely present in edible and medicinal plants. Real-time detection of flavonoids is a key step in the quality control of diverse matrices closely related to social, economic, and health issues. Traditional detection methods are time-consuming and require expensive equipment and complicated working conditions. Therefore, electrochemical sensors with high sensitivity and fast detection speed have aroused extensive research interest. Carbon nanomaterials are preferred material in improving the performance of electrochemical sensing. In this paper, we review the progress of electrochemical sensors based on carbon nanomaterials including carbon nanotubes, graphene, carbon and graphene quantum dots, mesoporous carbon, and carbon black for detecting flavonoids in food and drug homologous substances in the last four years. In addition, we look forward to the prospects and challenges of this research field.
