TLDR
In this article, a room-temperature motion sensor with record sensitivity was created using a levitating silica nanoparticle and feedback cooling to reduce the noise arising from Brownian motion enables a detector that is perhaps even sensitive enough to detect non-Newtonian gravity-like forces.Abstract:

Single nanoparticle sensing with nanoelectromechanical resonators operating at nonlinear regime
TL;DR: Yüksel et al. as discussed by the authors developed a measurement architecture to operate at the nonlinear regime and measure frequency shifts induced by analytes in a rapid and sensitive manner, which can be used for thin nanomechanical structures which possess a limited dynamic range.

A nanostructured surface increases friction exponentially at the solid-gas interface
TL;DR: In this article, the authors report experimental results of dissipation showing exponential dependence on viscosity for oscillating surfaces modified with nanostructures, and attribute the observed exponential enhancement to the stochastic nature of interactions of many coupled nano-structures with the gas media.
Journal ArticleDOI
Tuneable Gaussian entanglement in levitated nanoparticle arrays
TL;DR: In this paper , a variable, deterministic scheme to generate Gaussian entanglement in the motional steady state of levitated nanoparticles using coherent scattering is proposed, which can be used to couple and entangle nanoparticles directly or via an optical bus.

Higher order correlations in a levitated nanoparticle phonon laser
TL;DR: In this paper, the authors present theoretical calculations of higher order correlations for a phonon laser, demonstrated recently using an optically levitated nanoparticle, and show that the results for steady state and transient correlations agree well with experimental data.

Single spin detection by magnetic resonance force microscopy
TL;DR: The long relaxation time of the measured signal suggests that the state of an individual spin can be monitored for extended periods of time, even while subjected to a complex set of manipulations that are part of the MRFM measurement protocol.

Single spin detection by magnetic resonance force microscopy
TL;DR: In this article, the authors reported the detection of an individual electron spin by magnetic resonance force microscopy (MRFM) and achieved a spatial resolution of 25nm in one dimension for an unpaired spin in silicon dioxide.

Zeptogram-Scale Nanomechanical Mass Sensing
TL;DR: Analysis of the ultimate sensitivity of very high frequency nanoelectromechanical systems indicates that NEMS can ultimately provide inertial mass sensing of individual intact, electrically neutral macromolecules with single-Dalton (1 amu) resolution.

A nanomechanical mass sensor with yoctogram resolution
TL;DR: This unprecedented level of sensitivity allows us to detect adsorption events of naphthalene molecules, and to measure the binding energy of a xenon atom on the nanotube surface, which could have applications in mass spectrometry, magnetometry and surface science.

On the Resistance Experienced by Spheres in their Motion through Gases
TL;DR: In this article, the authors derived the force exerted by the impinging molecules leaving the surface depending on how they leave, assuming the usual Maxwellian distribution of velocities in the gas, the force was found to be M where M=(4π/3) Nma2cmV, N, m, a, and V being the number per unit volume, mass, radius, and mean speed of the molecules and V the speed of a droplet.
