Plasmonic Nanohole Arrays for Real-Time Multiplex Biosensing
نویسندگان
چکیده
Large-scale studies of biomolecular interactions required for proteome-level investigations can benefit from a new class of emerging surface plasmon resonance (SPR) sensors: nanohole arrays and surface plasmon (SP) enhanced optical transmission. In this paper we present a real-time, label-free multiplex SPR imaging sensor in a microarray format. The system presented is built around a low-cost microscope with laser illumination, integrated with microfluidics. The specific binding kinetics of biotin and streptavidin are measured from several sensing elements simultaneously, demonstrating the feasibility of using nanohole arrays as a high-throughput SPR microarray sensor.

High-throughput Fabrication of Plasmonic Nanohole Array Sensors for Label-free Kinetic Biosensing
In this work, we demonstrate high-throughput fabrication of periodic metallic nanohole arrays in an almost centimeter square area through simple metal deposition and peeling off processes, called template stripping [1]. A thin silica layer is used to protect the template-stripped Ag nanoholes from unwanted oxidation and also to provide a robust surface on which lipid membranes can be formed. We...

In this work we present a surface plasmon resonance sensor based on enhanced optical transmission through sub-wavelength nanohole arrays. This technique is extremely sensitive to changes in the refractive index of the surrounding medium which result in a modulation of the transmitted light. The periodic gold nanohole array sensors were fabricated by high-throughput thermal nanoimprint lithograp...

Surface plasmon resonance (SPR) imaging is a powerful technique for high-throughput, real-time, label-free characterization of molecular interactions in a microarray format. In this paper, we demonstrate SPR imaging with nanohole arrays illuminated by a laser source. Periodic nanoholes couple incident photons into SPs, obviating the need for the prism used in conventional SPR instruments, while...
