Optimization of plasmonic nanostructure for nanoparticle trapping
journal contribution
posted on 2024-07-09, 15:03 authored by Jingzhi Wu, Xiaosong GanWe present a detailed analysis of nanoparticle trapping using plasmonic nanostructures, which predicts an improvement of two orders of magnitude in trapping force obtained by optimizing the plasmon resonance of the nanostructures. As the result, a total of four orders of magnitude enhancement in trapping force can be achieved comparing to the case without the nanostructures. In addition, it is illustrated that tuning the resonance wavelength is achievable by varying the diameter and/or the height of the nanorods.
