Novascan Technologies provides particle attachment to AFM probes. Our expericed technicians utilize a number of attachment methods for mounting particles ranging in size from 600 nm to 30 μ. Standard particle types and sizes appear below. We also welcome the opportunity to mount client-supplied custom partcles.

Particle probes can be further modified with the application of defined surface chemistries or coating with metallic surfaces. See the products listed below for further information.

• Inter- and Intra-molecular Force Measurement
• Chemical Sensing and Detection
• Hydrophilic/Hydrophobic Interaction
• Attractive/Repulsive Regimes
• Adhesion Forces
• Unbinding Forces
• Surface Mapping
