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.
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.
