Distribution Time of Gold Nanoparticles Pass through the Solid State Nanopore in Deionized Water

Nanopore has the proming to be used as the detection senser for the single molecule at single molecular level or the nanoparticles in different meterials. The diameters of the nanopores can be changed in a large rang with the increasing fabrication technology. For this case, the nanopore could be used as particles‘ sizes senser. We used 15nm gold nanoparticles as exsamples to analyze the effects of nanopore/nanoparticle ratio in deionized water. In the detection experiments, we found that the gold nanoparticles would pass through the nanopore in different behaves. Besides, the diameters of the nanopores might effect the precision accuracy of the translocation events. In view of the former results, we notice that on the basis of nanopore detection technique, nanoparticles translocation share many similarities with DNA.
