Presently, biological micromanipulators are based on suction using micropipettes to grasp objects. New technologies and materials are necessary for better micromanipulation of soft biomedicine targets.
The micropipette-based and other types of micromanipulators that are currently employed for biological application lack accurate force control and may cause damage to the cells or tissues. Conventional electric motors and their associated gear boxes have also reached their limits despite their miniaturisation.
