“…Recent research could find colorimetric methods being used to determine Vit D (Lee et al 2017;Keyfi et al 2018), Vit C (Kalaiyarasan and Joseph May 2019), and B1 (Duenchay et al 2020). Surface plasmon resonance (SPR) and localized surface plasmon resonance (LSPR)-based sensing have also generated a lot of interest for Vit A (Prakashan et al 2019), Vit D (Jo et al 2021), Vit C (Zhu et al 2020a), and Vit B3 (Verma and Gupta 2013) detection. Both electrochemical and optical sensing techniques are in high demand due to their simplicity of use, low cost, and increased performance.…”

Vitamins are essential nutrients that aid in metabolism, cell growth, and the appropriate functioning of other biomolecules. They are required for the proper functioning of various systems in human body. Both vitamin shortage and excess can pave the way for a variety of illnesses. They enter the body via food and supplements eaten, making it critical to measure the vitamin concentrations in food, medicines, and biological fluids. The concentrations of these vitamins are determined using a variety of techniques. The performance measure of the techniques like selectivity, sensitivity, and limit of detection is crucial in their utilization. Among the many techniques of determination, electrochemical sensing and optical sensing have garnered widespread interest because of their potential to improve performance. Additionally, the introduction of innovative materials has added a lot of benefits to sensing. The aim of this article is to summarize significant work toward recent improvements in electrochemical and optical methods for detecting different vitamins. Additionally, it attempts to assess the gaps in vitamin sensing in order to encourage researchers to fill such gaps that will benefit the community.

“…Most flat substrate-based LSPR sensors use glass as a flat substrate on which to deposit AuNPs [ 31 , 57 , 59 , 60 , 61 , 62 , 63 , 64 ]. One of the simplest ways to fabricate such LSPR sensing substrates is to dip glass coated with 0.5% 3-aminopropyltriethoxysilane (APTES) as an amine group linker into an AuNP solution ([ 57 ]; Figure 2 A).…”

“…Au nanorod (GNR) was also deposited on the glass and applied to detect various biomolecules [ 61 , 62 ]. To improve the LSPR signal of the GNR substrate, a signal enhancer molecule (i.e., berberine) was used for improving the LSPR signal shift [ 61 ].…”

“…This sensor could detect OTA, aflatoxin B1, ATP, and K + at sensitivities of 0.56, 0.63, 0.87, and 1.05 pM, respectively, accounting for a 1000-fold increase in the detection limit with a broad dynamic range of 10 pM to 10 μM with linearity. As another means to improve the LSPR signal, the surface of the GNRs was functionalized with citrate as a stabilizer [ 62 ]. The surface modification with citrate offered a good dispersion of the GNR particles without surfactant and high immobilization efficiency of GNR on substrate, resulting in a large peak shift.…”

Sensitive and accurate detection of small molecules from complex matrix has aroused increasing interest in many fields, yet remains an open challenge. Recent years have witnessed a considerable advance of aptasensors for diagnostic assay development towards diverse small molecules because aptamer is one of the most powerful classes of molecular receptors with advanced affinity and specificity. Herein, we reviewed the small‐molecule aptasensors in the past five years, focusing on the principles to specific applications in clinical diagnosis, food safety, and environmental monitoring. The first introductory section on the development of aptasensors in historical view and its analytical features contextualizes essential health‐related small molecules. The second part highlights the basic components of aptasensor and the detection principles of different sensors based on signal output modes. The subsequent part systematically discusses various small‐molecule sensing platforms by interfacing aptamers with diverse signal amplification strategies. Finally, challenges and perspectives for improving the aptasensor performance are also discussed. By describing biochemical and analytical procedures, this review highlights the optimal use of aptamers in the detection, quantification, and imaging of important health‐related small molecules and presents new insights, technical advances, and engineering strategies for practical applications.
