A new Voltametric sensor, based on molecularly imprinted polymer (MIP) for vitamin D3 Detection

Abstract

an extremely sensitive electrochemical sensor for vitamin D3 is fabricated based on hybrid imprinted polymer. A vitamin D3 absorptive molecularly imprinted polymer (MIP) are synthesized in the present of multi-walled carbon nanotubes (MWCNTs), and then mixed with graphite powder and n-eicosane as a binder for construction of carbon paste electrodes (CPEs). Electro oxidation of vitamin D3 is considered with this modified electrode. Several aspects of modified electrode construction was considered and improved. This linearity range of sensor was 5 × 10−8–7 × 10−6 M and lower detection limit was 3 × 10−8 M. The presented sensor was efficient for vitamin D3 quantification in real samples.
