“…The immunosensor showed an excellent concentration range of 0.1–500 ng mL −1 , with a LOD of 0.01 ng mL −1 . 134 In an aqueous solution, Men et al synthesized Au–Pd nanocrystals. Using an Au–Pd-modified GCE, D2, and D3 were electrochemically identified in a solution that contained both organic and inorganic components.…”

“…The immunosensor exhibited a great concentration range from 0.1 ng/mL to 500 ng/mL with the lowest limit of detection of 0.01 ng/mL. [78] Wadhwa et al designed novel graphene quantum dot-gold (GQD-Au) hybrid nanoparticles that were used as a sensing platform for developing a state-of-the-art electrochemical aptasensor for the detection of vitamin D 3 . The sensor gave a linear response in the concentration range of 1-500 nM, with LOD of 0.70 nM, LOQ of 2.09 nM.…”

Recent advancements in electrochemical sensors for the detection of vitamins, particularly vitamin D, have drawn a lot of attention due to their outstanding advantages of simplicity and high sensitivity. For the purpose of detecting vitamin D in this circumstance, recent research has focused on developing electrochemical sensors. Although there is always space for improvement, electrochemical sensors for vitamin D detection and its transformation into point‐of‐care devices have made great strides lately. For example, the development of innovative electrode materials that can increase sensitivity and selectivity continues to garner a lot of interest. New suggestions on adsorptive detections using vitamin D carriers like nanoclays or hydroxyapatite‐clay composites are being developed. These biosensors hold huge potential for the detection of cheap, disposable, and biodegradable solutions. Also, the biosensor could monitor the depletion of vitamin levels, providing a real‐time platform for the Internet of Medical Things, fifth‐generation wireless communications, and smartphone‐based electrochemical sensors. Currently, electrochemical sensors based on smartphones have been proposed to detect using various biomarkers for monitoring several changes in glucose, etc. We believe smartphone‐based electrochemical sensors and adsorptive sensing platforms provides a novel way toward point‐of‐care tests for identifying especially vitamin D deficiency and real‐time monitoring

“…In the field of VD electrochemical sensors based on carbon nanomaterials, Thangphatthanarungruang prepared a graphene nanocomposite sensor for simultaneously measuring vitamins (A, D, E and K) that are lipid-soluble in various matrix samples (infant milk, yogurt and parsley) (Thangphatthanarungruang et al, 2020). Anusha designed a label-free impedance sensor using ethyl-3-(3-dimethyl aminopropyl) carbodiimide-N-hydroxysuccinimide/graphitic carbon nitride-β-cyclodextrin (EDC-NHS/GCN-β-CD) @AuNPs composite to assay serum samples for the presence of 25(OH)D 3 (Anusha et al, 2022). It is less destructive to its biomolecular activity, thus improving the sensitivity of detection.…”

Lipid hormone is produced by highly differentiated endocrine cells and directly secretes into the blood circulation or tissue fluid to act as information transmission. It influences the physiological functions of the human body by controlling the metabolic processes of multiple tissue cells. Monitoring the levels of lipid hormone is of great importance for maintaining human health. The electrochemical sensor is considered as an ideal tool to detect lipid hormone owing to its advantages such as quick response, convenience and low economic costs. In recent 3 years, researchers have developed various electrochemical sensors for the detection of lipid hormone to improve their sensitivity or selectivity. The use of nanomaterials (such as carbon nanomaterials, precious metal and polymer) is a key research object and a breakthrough for improving the sensing performance of electrochemical sensors for detection of lipid hormone. This paper reviews and discusses the basic principle, nanomaterials, actuality and future development trend of electrochemical sensors for the detection of lipid hormone in the past 3 years.
