Trapping and Sensing Biomolecules and Nanoparticles
Researchers at Purdue University have developed a new method that could help solve the nanoparticle diffusion time issue as well as stabilize nano-objects in the hotspot of the aperture. Using light, a long range flow is induced that captures nanoparticles in a solution and delivers them to the aperture trap. This technique operates on a subsecond scale, beating the time limits of previous processes. In order to immobilize nano-objects on a hotspot of the aperture, researchers applied a DC or low frequency AC field, which essentially traps the nano-object on the hotspot. This is especially important for the aforementioned quantum emitters, as they interact positively with the hotspots and allow for more revealing information on quantum technology to be ascertained.
