This colloidal probe combines the well-known features of the proven Pyrex-Nitride AFM probes series such as high application versatility and compatibility with most commercial SPMs with a reproducible sphere radius instead of a sharp AFM tip. The excellent radius and the minimized variation of diameter provide reproducible signals.
Pyrex-Nitride AFM probes are designed for various imaging applications in contact or dynamic mode.
The so called "Colloidal Probe Technique", where single colloids are attached with polymer glue to AFM cantilevers for force measurements, offers possibilities for a better understanding of fundamental interactions in a variety of fields. Examples are adhesion phenomena, particle-surface interactions, mechanical properties, suspensions, hydrodynamics and boundary slip - to name just some out of an increasing number of applications.
The Pyrex-Nitride AFM probes have silicon nitride AFM cantilevers with very low force constants. The AFM probe series features a support chip that is made of Pyrex. The AFM cantilevers are stress compensated and have a 65 nm chromium / gold back side coating for high laser reflectivity.
The AFM probe offers unique features:
Only one AFM cantilever with sphere, please choose long or short!
Colloidal AFM probes based on PNP AFM cantilevers are not suitable for application in fluids. For this kind of application we recommend colloidal AFM probes based on qp-CONT or qp-SCONT AFM cantilevers.
