dc.description.abstractIn this paper we present recent advances in Förster resonance energy transfer (FRET) sensing and bioimaging using nontoxic silicon quantum dots. (SiQDs) In our work, we prepare SiQDs-dye conjugates, with SiQDs serving as the donor which are covalently attached to organic dye acceptors via self-assembled monolayer linkers. Enzymatic cleavage of the peptide leads to changes in FRET response which was monitored using fluorescence lifetime imaging microscopy (FLIM-FRET). The combination of interfacial design and optical imaging presented in this work opens new opportunities for bio-applications using nontoxic silicon quantum dots.en_US
