Engineered nano-sphere array of gold-DNA core–shells and junctions as opto-plasmonic sensors for biodetection

Abstract: Several engineered optoplasmonic structures including DNA rods as junctions between GNPs for controlling and improving the absorbance were proposed.

“…Besides nanoparticles, several other nanomaterials have also been explored for their possible contributions in enhancing the performance of plasmonic sensors. Some of these include nanorods [92][93][94], nanowires [95][96][97][98][99], nanosheets [100][101][102], nanotubes [103,104], fullerenes [105,106], TM dichalcogenides, [107,108] hexagonal boron nitride [109,110], and core-shells [111][112][113]. Studies focussing on the integration of nanomaterials in plasmonics for sensing applications have led to breakthrough technologies such as wearable plasmonic sensors [114,115] and multi-parameter sensing [116][117][118].…”
