Selective labeling of the endoplasmic reticulum in live cells with silicon quantum dots.

چکیده
A simple and novel approach was developed to obtain water-dispersible silicon quantum dots (Si-QDs) of low toxicity that were able to selectively label the endoplasmic reticulum (ER) in live cells. A block copolymer (Pluronic F127) was used to coat the surface of Si-QDs. Si-QDs form aggregates with diameters of 20-40 nm and show an outstanding optical stability upon UV irradiation. Our F127-treated Si-QDs would be a powerful tool for long-term real-time observation of the ER in live cells.

Background: Defects in endoplasmic reticulum homeostasis are common occurrences in different diseases, such as diabetes, in which the function of endoplasmic reticulum is disrupted. It is now well established that ion channels of endoplasmic reticulum membrane have a critical role in endoplasmic reticulum luminal homeostasis. Our previous studies showed the presence of an ATP-sensitive cationic...
