The hypersensitive detection of metal ions and amino acid becomes more important for environmental and human physical conditions monitor but remains still a great challenge. In this work, we have reported a green and straight forward procedure (solvothermal treatment) for the synthesis of N-doped hemicellulose-based carbon quantum dots (N-H-CQDs) used as an "off-on" fluorescence sensor for ultrasensitive detecting Ag+ ion and L-Cysteine (L-Cys). During this process, hemicellulose used as carbon source and nitrogen-rich deep eutectic
