Novascan Technologies microfabricates the highest quality, most reliable and most published AFM probes with Bead, Sphere and Colloids attached to AFM cantilevers available. Many of our skilled technicians individually have over 15 years of experience mounting particles ranging in size from 600 nm to over 30 μm. Using these optimized production techniques, Novascan can offer you the best AFM probe at a very modest price. Our best selling particle probes are listed below. We also welcome the opportunity to fabricate using client-supplied custom particles or client supplied cantilevers.

Bead, Sphere and Colloidal AFM probes can be further modified with the application of defined surface chemistries such as carboxyl, methyl, hydroxyl, amine, biotin, streptavidin, succinimide, maleimide, antibody or metallic coating such as gold and platinum. Our the best selling coated particle AFM probes are also listed below.

Non-Calibrated and Pre-Calibrated AFM Bead, Sphere and Colloidal probes -- As you may be aware the reported nominal spring constant values from all AFM probe manufacturers are well known to be very inaccurate, often by tens of percent or more. As such if you are measuring forces, the manufacturer's nominal value should never be used! Instead cantilever spring constants must be calibrated for each probe if you want accurate and reproducible data. Further, calibration should generally be performed BEFORE MODIFICATIONS because of the added mass. In addition to Non-Calibrated probes, Novascan now offers the best Pre-Calibrated AFM Bead, Sphere and Colloidal probes to save you time and prevent inaccurate data.
