Nano-sized quantum dots(QDs) exhibit uniquely optical properties that are tunable with different sizes and shapes.QDs can emit narrow symmetric bands under a wide excitation range,possess antiphotobleaching stability,and be bio-functionalized on the large surface area.Therefore,QDs are attractive vectors for imaging-guided therapy.Small-interfering RNA(siRNAs)-based therapeutics hold great potential to target a large part of the currently undruggable genes,but overcoming the lipid bilayer to deliver siRNA into cells has remained a major challenge to solve for widespread development of siRNA therapeutics.In this mini-review,we focus on theranostic QD/siRNA assembles for enhancing delivery of siRNA and facilitating evaluation of therapeutic efficacy via imaging of QDs,with special attention to carbonaceous QDs for delivery of siRNA.
