A critical review of electrochemical and optical Vitamin B6 sensing: evolution of biosensor platforms based on advanced nanosystems.

Abstract\nHIGHLIGHTSVitamin B6 (VB6) is a member of the water-soluble B vitamins which have a vital performance in nervous system operating activities. VB6 is highly demanded to maintain excellent skin and immune systems in the human body. furthermore, VB6 is tremendously substantial in the functions of some enzymes that participate in the metabolism of proteins, amino acids, etc. The deficiency of VB6 will eventuate in anemic situations and may lead to permanent injuries in the brain. moreover, recent studies disclosed that adequate Vitamin B6 in the human body can decrease the intensity of illnesses such as diabetes, stress, etc., in patients with COVID-19 infections. Thus, the detection of VB6 from real samples is crucial to control the amount of this vitamin in biological fluids and to monitor the pharmaceutical dosage quality. Various analytical approaches have been employed for the VB6 detection in biological and pharmaceutical samples. Although biosensing and sensing approaches hold several obvious advantages such as simplicity, capability for miniaturization, quick response time, etc. from other analytical methods. Hence, through the last decades, designing and fabricating biosensors with sufficient sensitivity and selectivity have been investigated by many researchers in order to detect VB6. The purpose of this review is to illustrate the importance of diverse electrochemical and optical approaches for VB6 detection. Additionally, novel VB6 detection techniques based on electrochemical, optical, and conventional methods have been considerably discussed, and compared with each other. Furthermore, a comprehensive summary of the current limitations and future challenges in VB6 analysis are explained and also create a pathway for subsequent expansions and applications.Vitamin B6 is an essential compound for proper function of human body.Various nanomaterial-based methods such as conational approach, electrochemical biosensing and apta-sensing analyses for Vitamin B6 detection has been developed.Different techniques for detecting of Vitamin B6 have been comprehensively discussed.Various electrochemical sensors fabrication and its application in Vitamin B6 detection with nanomaterials have been assessed.The article points out the recent progress limitations, and also the upcoming tasks in the successful sensor fabrication with the functionalized nanomaterials.Vitamin B6 is an essential compound for proper function of human body.Various nanomaterial-based methods such as conational approach, electrochemical biosensing and apta-sensing analyses for Vitamin B6 detection has been developed.Different techniques for detecting of Vitamin B6 have been comprehensively discussed.Various electrochemical sensors fabrication and its application in Vitamin B6 detection with nanomaterials have been assessed.The article points out the recent progress limitations, and also the upcoming tasks in the successful sensor fabrication with the functionalized nanomaterials.
