Benchmarking Smartphone Fluorescence-Based Microscopy with DNA Origami Nanobeads: Reducing the Gap toward Single-Molecule Sensitivity

Read open access article here.

Nice paper! GATTA-Beads imaged with smartphone camera. The paper shows how Gattaquant GATTA-Beads can be applied to benchmark the sensitivity of instruments.

Gattaquant Fluorescent beads are important microscopy tools which can be used for calibration of microscopes, particle tracking or quantitative determination of point spread functions especially in STED microscopy. Particularly for the last point a small structure size keeping a high brightness is an immense advantage. Products from the GATTA-Bead series fulfill this requirement perfectly with a diameter of only 23 nm. Additionally, they show a clearly improved homogeneity and flexibility compared to other beads. We offer GATTA-Beads in the colors red (ATTO 647N), orange (ATTO 594), green (ATTO 542) and blue (Oregon Green 488). Moreover, we offer alternative dyes which are indicated on the table below.

On request we can also design special solutions for your specific requirements. All samples will be delivered on a sealed glass slide which you can comfortably put directly on your microscope.
