a Schematic of optical tweezers used for nanopore DNA detection [48]. When the optical tweezers system is in equilibrium, the optical force (Fot) is equal to the electric field force (Fel). b Schematic of magnetic tweezers used for nanopore DNA detection [49]. When the magnetic tweezers system is in equilibrium, the magnetic force (FMt) is equal to the electric field force (Fel). c Schematic of AFM used for nanopore DNA detection [50]. d Schematic of TFFS used for nanopore DNA detection [51]
