Confocal microscope images of HT-1080 cells exhibiting internalised QDs. First row: negative control; second row: donor (b); third row: acceptor (b); fourth row: donor (b) and acceptor (b) added simultaneously; fifth row: donor (b) and acceptor (b) with preincubation. First column: excitation 543 nm, emission 603 nm; second column: excitation 633 nm, emission 668 nm; third column: overlay of green and red channels with bright field. Arrows indicate green QDs.
