About Nanonewtons
A nanonewton (nN) is 10⁻⁹ N - the force scale of AFM, MEMS, and nanoscale adhesion. AFM contact-mode tip-sample forces are held to 1-100 nN to image surfaces without damage. A single gecko seta generates ~200 nN of adhesion via van der Waals forces; one million setae per foot give ~10 N total grip. Smartphone MEMS accelerometers sense nanonewton inertial forces from proof-mass displacements. Carbon nanotubes fracture at forces in the nanonanonewton range per tube. CubeSat cold-gas microthrusters produce single-digit nN thrust for attitude control. 1 nN = 10⁻⁹ 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.
