We have searched for large deviations from Newtonian gravity by means of a finite-frequency microcantilever-based experiment. Our data eliminate from consideration mechanisms of deviation that posit strengths $\ensuremath{\sim}{10}^{4}$ times Newtonian gravity at length scales of $20\text{ }\text{ }\ensuremath{\mu}\mathrm{m}$. This measurement is 3 orders of magnitude more sensitive than others that provide constraints at similar length scales.

A review of short-range gravity experiments in the LHC era (2014, methodology): “Very high-precision experiments were performed (Figure 24) by the Stanford University group using cantilevers (Smullin et al. 2005, Geraci et al. 2008, Chiaverini et al. 2003).”
Classical and Quantum Consistency of the DGP Model (2004, background): “In principle this is the length scale below which we cannot compute the gravitational potential at the surface of the Earth! Notice that this scale exceeds by almost 2 orders of magnitude the present experimental bound on modifications of gravity [25, 26, 27].”
