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:

Feedback Control of Optically Trapped Nanoparticles and its Applications
TL;DR: In this article, the authors demonstrate a solvable model of Feynman's ratchet using a silica nanoparticle inside a feedback controlled one dimensional optical trap, which can be used to stabilize and cool the two torsional degrees of freedom of the particle along with the three center of mass DOF.

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.
Journal Article
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.
