We introduce a nanoplasmonic platform merging multiple modalities for optical trapping, nanospectroscopy, and biosensing applications. Our platform is based on surface plasmon polariton driven monopole antenna arrays combining complementary strengths of lo ...
The electric field enhancement associated with detailed structure within novel optical antenna nanostructures is modeled using the surface integral equation technique in the context of surface-enhanced Raman scattering (SERS). The antennae comprise random ...
This work focuses on trapping subwavelength objects using resonant plasmonic structures. Trapping entities include latex spheres, living cells and metallic particles; the plasmonic structures involved include subwavelength disks, subwavelength apertures, a ...
In this thesis we study the properties of optical wire antennas. As experimental method for our investigations we use apertureless near-field optical microscopy. This technique achieves high spatial resolution well beyond the diffraction limit by utilizing ...
The fabrication of gold nanodots by stencil lithography and its application for optical biosensing based on localized surface plasmon resonance are presented. Arrays of 50−200 nm wide nanodots with different spacing of 50−300 nm are fabricated without any ...
This work presents analyses and developments in nanofabrication using stencil lithography and its application for electronics and biosensing. Metallic nanostructures are fabricated using stencil lithography studying the pattern transfer from the stencil to ...
We study the trapping of nanoscopic objects in the near-field of plasmonic nanostructures and demonstrate experimentally that 10nm particles can be trapped in the 15nm gap of a dipole antenna. Applications for biosensing are discussed. ...
