About Attonewtons
An attonewton (aN) is 10⁻¹⁸ N - the force scale of individual photon recoil and quantum vacuum effects. The thermal noise floor of an AFM cantilever at room temperature is ~1-10 aN/√Hz. A 532 nm photon absorbed by a trapped ion imparts ~0.3 aN of recoil. Casimir forces between conducting surfaces 10-100 nm apart are 1-100 aN. NEMS resonators have demonstrated force sensitivity below 1 aN/√Hz, enabling single-molecule adsorption detection. Optomechanical cavities probe radiation pressure at the attonewton scale to test quantum measurement limits. 1 aN = 10⁻¹⁸ N.
About Millinewtons
A millinewton (mN) is 10⁻³ N - the force scale of lightweight structures and precision connectors. A mosquito weighs ~1-3 mN; a grain of rice ~29 mN; a paper clip ~40 mN. USB connector insertion forces are specified at 40-80 mN; keyboard switch actuation (ISO 9241) 40-80 mN. Piezoelectric hard drive head positioning actuators deliver 10-100 mN. Spider dragline silk (4 µm diameter) breaks at 40-60 mN - among the highest specific strengths in nature. Flexible electronics peel-force and thin-film adhesion tests also operate in the mN range. 1 mN = 10⁻³ N.
