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 Piconewtons
A piconewton (pN) is 10⁻¹² N - the force scale of molecular biology and nanotechnology. Optical and magnetic tweezers apply 0.1-100 pN forces to single DNA strands and protein complexes. Unzipping one DNA base pair requires ~10-15 pN; a kinesin motor protein stalls at ~7 pN. AFM cantilevers resolve piconewton van der Waals forces between single atoms and surfaces. The covalent C-C bond ruptures under ~4,000 pN in controlled AFM pulling experiments. These forces underpin mechanobiology, drug-target mechanics, and nanofabrication. 1 pN = 10⁻¹² N.
