The paper considers the conditions for capturing a dielectric nanoparticle in a liquid by an optical tweezers trap. It is shown that the displacement of a nanoparticle from the equilibrium position under the action of a local physical field not associated with a laser trap shaper can be used to create a nanosensor for fields of physical or chemical origin.
