One-pot microwave-assisted in situ reduction of Ag+ and Au3+ ions by Citrus limon extract and their carbon-dots based nanohybrids: a potential nano-bioprobe for cancer cellular imaging

In the present study, we demonstrate a rapid, in situ reduction of metal (Ag + and Au 3+ ) ions and subsequent carbonization of Citrus limon (lemon) extract to synthesize highly luminescent carbon-dots (C-dots) and their metal nanohybrids (MCNs) using one-pot microwave (MW) assisted technique within...

Description
Summary:In the present study, we demonstrate a rapid, in situ reduction of metal (Ag + and Au 3+ ) ions and subsequent carbonization of Citrus limon (lemon) extract to synthesize highly luminescent carbon-dots (C-dots) and their metal nanohybrids (MCNs) using one-pot microwave (MW) assisted technique within 6 min. In principle, l -ascorbic acid, citric acid and flavonoids reduce metal ions into corresponding metal nanoparticles followed by carbonization of carbohydrates in the lemon extract along with externally added ethylenediamine (EDA) to form EDA-functionalized C-dots based nanohybrids. The synthesized pristine C-dots, Ag/C-dot and Au/C-dot nanohybrids (
