Applications:

Tipless AFM Cantilevers and Cantilever Arrays

Description:

NanoWorld Pyrex-Nitrid probes are designed for various imaging applications in contact or dynamic mode. Tipless cantilevers are often used for applications that require functionalization of the cantilever surface or attaching objects (like spheres or particles) to the end of the cantilever. These and various other applications are especially interesting for the fields of life science and biology.

The Pyrex-Nitrid probes have silicon nitride cantilevers with very low force constants. The probe series features a support chip that is made of Pyrex. The TR series features two different triangular cantilevers. Both sides of the chip have identical cantilevers.

All chips are pre-separated prior to shipment and come in Gel-Pak containers.

Gold Coating / Gold Reflex CoatingThe gold coating consists of a 35 nm thick gold layer deposited on the front side of the cantilevers.The gold reflex coating deposited on the detector side of the cantilevers enhances the reflectance of the laser beam. As the coating is almost stress-free the bending of the cantilevers due to stress is less than 2 degrees.
