Qui, descriviamo una configurazione di pinzette magnetiche ad alta velocità che esegue misurazioni nanomeccaniche su biomolecole sensibili alla forza alla velocità massima di 1,2 kHz. Presentiamo la sua applicazione a forcine di DNA e complessi SNARE come sistemi modello, ma sarà applicabile anche ad altre molecole coinvolte in eventi meccanobiologici.
