N-doped photoluminescent carbon dots from water hyacinth for tumour detection

N-doped photoluminescent carbon dots from water hyacinth for tumour detection: Publication date: Available online 5 February 2020Source: Materials Today: ProceedingsAuthor(s): Anju Paul, Manju KurianAbstractEarly diagnosis of life intimidating diseases such as cancer could drop down the mortality rate to a great extent. Carbon dots, being fluorescent materials hold a promising impact on the field of biomedicine. Herein, we report a single step, facile hydrothermal method for the synthesis of surface passivated, water soluble, spherical, fluorescent nitrogen doped carbon dots (N-CDs) from water hyacinth. From FT-IR and Raman Spectroscopic studies, surface functionalization was identified and nitrogen doping was confirmed by X-ray photoelectron spectroscopy. Optical properties were investigated by UV–Visible spectrophotometer and Fluorescence spectrometer and found t...
