Colloidal probes

Special colloidal probes for direct surface force measurement, measurement of adhesion forces, study of colloidal interactions between particle and surface and many other applications.

We offer two types of the probes:

Special colloidal probes with spherical particles calibrated by size and fixed on the very end of the needle tip. The particles diameter have sizes 250nm, 650nm and 900nm what gives to colloidal probes the possibility to preserve the AFM resolution at the submicron level.
Colloidal probes with near perfect micro-spheres of various materials attached at the end of tipless cantilevers.
