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 [Formula presented] times Newtonian gravity at length scales of [Formula presented]. This measurement is 3 orders of magnitude more sensitive than others that provide constraints at similar length scales.
