Carbon dots-modified chitosan based electrochemical biosensing platform for detection of vitamin D

Here in, a carbon dots (CDs)-modified chitosan (CH) based biosensing platform was fabricated for vitamin D2 detection. Carbon dots were synthesized through microwave pyrolysis method, and characterized with transmission electron microscopy, Raman spectroscopy, Fourier transform infrared spectroscopy, and UV/VIS spectroscopy. Chitosan (1%) solution was prepared in acetic acid (1%) solution and followed by the addition of CDs to prepare the carbon...
