Informing the Brightest Minds

Aggregating several quantum dots into a protective polymer envelope, MultiDots provide a brighter, longer-lasting signal with sharp peaks that wipe the ambiguity out of your research. Now imagine all that with magnetic capabilities—allowing you to concurrently observe and manipulate analytes.

Brightness and Excitation

The broad absorption spectrum shared by MultiDots of all colors means you can perform multiplex studies with a single light source. Meanwhile, the sharp spectral peaks produced will ensure your results are clear of emission overlap.

Photostability

Now you can store tagged cells and re-examine them later, without losing signal to photobleaching. When compared to Alexa dyes and other organic dyes, such as FITC, MultiDots do not photobleach when using powerful lasers, such in confocal microscopy.

Access

Although composed of several quantum dots, water-soluble MultiDots remain small enough to access the areas you need.

“…our electron microscopy has shown these novel nanoparticles can indeed get access to the myofilament lattice within muscle cells.” Prof. Beth Brainerd, Professor of Medical Science, Brown University
