This paper reports the synthesis of carbon quantum dots (CQDs) from chitin nanofibers (CNFs) as a newcarbon source via microwave assisted-hydrothermal route within three minutes. The FL of as-preparedCQDs can be quenched after addition of Cu2+ ions. However, in the presence of D-Penicillamine (DPA), Cu2+ ions prefer to bind to DPA owing to their high affinity toward DPA and subsequently the FL of CQDs iseffectively recovered. Therefore, here for thefirst time the Cu2+ ion modified CQDs (CQDs-Cu2+) wasutilized as a FL chemoprobe for quantitative determination of DPA in biological and pharmaceuticalsamples with satisfactory results.
