In recent years the field of optical microscopy has developed several new technologies which have allowed to the breaking of the diffraction limit postulated by Ernst Abbé. However, due to the lack of standardized methods for measuring and quantifying the resolution obtained by such a system, the user could not be sure that the used microscope provides the resolution which is required for his experiment. Now Gattaquant have introduced tools and methodologies which address these needs, providing convenient, fast and accurate products to measure resolution for these ground-breaking new microscopy techniques.
Lastek have been appointed distributors for Gattaquant in Australia and New Zealand, to complement their portfolio of advanced microscopy capabilities from Abberior Instruments and other leading suppliers.
Gattaquant's innovative nanorulers now allow a fast, easy and precise determination of resolution values in any common super-resolution system (STED, SIM, (d)STORM, DNA-PAINT) as well as in diffraction limited applications (GATTA-Confocal). On the one hand the instantaneous visible, significant result makes it easy for users to proof their microscope’s resolution and on the other hand provides an opportunity for microscope manufacturers to demonstrate the performance of their products in an eye-catching way.
Additionally, GATTAquant have developed point-like light sources performing the highest brightness density in the world. These gattabeads are ideal tools for exact and quantitative characterizations of super-resolution microscopes (especially STED systems) or as reference points for drift correction or particle tracking. Hereby gattabeads are not only much brighter than conventional beads of comparable size but also provide a higher homogeneity and flexibility.
