In the world of nanotechnology, plasmonic nanostructures, which support electromagnetic fields, are important for manipulating nanoscale objects. Currently, controlling the dynamics of suspended particles can be difficult. Some approaches include plasmonic nanotweezer systems, which are slow and inefficient and there are no known plasmonic tweezers that can rapidly deliver and "lock" nano-objects in specific hotspots. One approach is to use an AFM tip to pick and move the object to the desired location which is very complicated and needs expensive equipment. Hence, there is a need for easier manipulation of nanostructures for this purpose.

To address such issues, researchers at Purdue University have developed a hybrid device and method for the precise placement of nanostructures near the plasmonic antenna. It is possible to "print" the nanoparticles in the plasmonic hotspots by applying a DC electric field, or to manipulate nanoparticles such as pharmaceutical particles and place them close to these plasmonic hotspots to allow detection via Raman spectroscopy. This product is advantageous as it only requires a plasmonic nanostructure chip, a light source, and a function generator, making it cost-effective. Additionally, it is reconfigurable and reusable, making this technology superior to current approaches in nanostructure manipulation.
