Study of the noise of micromechanical oscillators under quality factor

Description: The performance of devices based on micro- and nanomechanical oscillators depends critically on the quality factor (Q). The quality factor can be externally increased about two orders of magnitude by coherent amplification of the oscillation at resonance with a fast feedback amplifier. Here, theory ...

Energy dissipation in tapping-mode scanning force microscopy with low quality factors

Description: The phase angle of the cantilever oscillation in tapping mode scanning force microscopy can be related to the energy dissipated per oscillation period through an analytical model that assumes a sinusoidal movement of the cantilever [J. Tamayo and R. García, Appl. Phys. Lett. 73, 2926 (1998); J. P. C...

Nanomechanical systems: Inside track weighs in with solution

Description: The performance of biosensors that rely on tiny vibrating cantilevers suffers when they are operated in a liquid. The solution is to place the liquid inside the cantilever. ©2007 Nature Publishing Group. , Peer Reviewed

Structure of human chromosomes studied by atomic force microscopy

Description: In this work human chromosomes have been treated with RNase and pepsin to remove the layer of cellular material that covers the standard preparations on glass slides. This allows characterization of the topography of chromosomes at nanometer scale in air and in physiological solution by atomic force...

Structure of human chromosomes studied by atomic force microscopy: Part II. Relationship between structure and cytogenetic bands

Description: In the first part of this work, human chromosomes were characterized by atomic force microscopy (AFM) in air and in aqueous solution. The analysis of the images suggests that the last level of organization consists of a radial arrangement of chromatin loops which are anchored to a fiber which is fol...
