Buyer’s Guide

Scanning probe microscopy

Sponsored by Bruker Nano Surfaces

PeakForce Tapping™ is the most significant breakthrough in AFM technology since the advent of TappingMode™. By applying a precisely controlled force response curve at every pixel, PeakForce Tapping permits the use of reduced imaging forces, protecting both fragile probes and samples with no decrease in image resolution.
