AFM Control System for Video Rate Imaging and Manipulation

Executive SummaryAtomic force microscopes (AFM), are a very high-resolution type of scanning probe microscope. Imaging speeds, however, are limited by the inertia and resonances of the scanning systems and of the AFM cantilever. It is desirable to increase the scan speed of applications without the need to make physical changes to the dynamics of the...

Efficient Selection of Carbon Nanotubes by Desired Properties

IntroductionIn the beginning powder form, carbon nanotubes (CNTs) have a wide range of physical dimensions and electrical properties at the level of individual CNTs. A number of researchers have tried various methods of selecting and manipulating (CNTs) produced in batch quantities. However, these processes do not select CNTs by specific dimensions,...

Improved AFM Manipulation of Nano-Objects

IntroductionIn traditional atomic force microscope (AFM) based nano-manipulation systems, a cantilever is used as the probe tip to manipulate nano-sized objects. Because of the need for good contact with the object, a "pre-loaded" force must be exerted by the cantilever on the object, making it difficult for an operator to "feel"...

Improved Force Sensing on Nano-Manipulated Objects

IntroductionEfficient manipulation of nano-sized objects will require an effective means for sensing the force exerted by a nanoprobe on the object. Current PZT (lead zirconium titante)-based piezoelectric force sensors are limited in their sensitivity.Description of TechnologyBy using a highly sensitive polyvinylidene fluoride (PVDF) piezoelectric...

Real-time Nanomanipulation Using AFM

IntroductionAn efficient system for manipulation of nano-sized objects would be greatly aided by the ability of an operator to "feel" the objects he/she is manipulating.Description of TechnologyThe invention proposes an atomic force microscope (AFM) based Augmented Reality System consisting of an AFM connected to a haptic device allowing the...
