Electrochemical sensors, which offer great performance with inexpensive additives, appeal to all market groups, allow the detection of vitamins, will likely continue to improve, and become a significant part of daily life in the future. This review explained why we think it will be life-changing, a few application areas that we think will have an immediate impact on nanosensing opportunities.

Abstract

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
