About Micronewtons
A micronewton (µN) is 10⁻⁶ N - the force scale of satellite microthrusters and MEMS actuators. Ion FEEP microthrusters on CubeSats produce 1-1,000 µN to compensate atmospheric drag at sub-500 km altitudes. Newton's law gives F = Gm₁m₂/r² ≈ 6.674 µN between two 1 kg masses 10 cm apart. Comb-drive electrostatic actuators in lab-on-a-chip devices operate at micronewton forces for cell sorting. AFM cantilevers mapping cell stiffness apply 10-100 µN. Red blood cells deform measurably at ~10-20 µN - an optical tweezers assay used to detect malaria. 1 µN = 10⁻⁶ N.
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.
