Fluorescent quantum dots have been used to develop biosensing platforms and drug delivery in microfluidic devices. Quantum dots are useful due to their small size, precise excitation wavelength, and high quantum yield. These are advantages over traditional dyes which may interfere with the activity of the studied compound. However, the bulk creation and conjugation of quantum dots to molecules of interest remains a challenge. Microfluidic devices that conjugate nucleotides with quantum dots have been designed to solve this issue by significantly reducing the conjugation time from two days to minutes. DNA-quantum dot conjugates are of importance to detect complementary DNA and miRNA in biological systems.
