Mid-infrared plasmonic biosensing with graphene

Hatice Altug, Dordaneh Etezadi, Daniel Rodrigo Lopez, Odeta Limaj

Infrared spectroscopy is the technique of choice for chemical identification of biomolecules through their vibrational fingerprints. However, infrared light interacts poorly with nanometric-size molecules. We exploit the unique electro-optical properties o ...

LSPR Chip for Parallel, Rapid, and Sensitive Detection of Cancer Markers in Serum

Sebastian Maerkl, Jose Luis Garcia Cordero

Label-free biosensing based on metallic nano-particles supporting localized surface plasmon resonances (LSPR) has recently received growing interest (Anker, J. N., et al. Nat. Mater. 2008, 7, 442-453). Besides its competitive sensitivity (Yonzon, C. R., et ...

A new strategy for improving fluorescent immunoassays using photonic crystals

Hans Peter Herzig, Elsie Barakat

The most widely used substrates for fluorescent immunoassay are based on transparent materials such as glass or plastic with almost no optical functionality. Very recently, optical nanostructures made of metal on dielectrics have been proposed to perform p ...

Hybridization chain reaction performed on a metal surface as a means of signal amplification in SPR and electrochemical biosensors

Carlotta Guiducci, Fabio Mario Spiga, Giampaolo Zuccheri

A more specific and intense signal is desirable for most kinds of biosensors for biomedical or environmental applications, and it is especially so for label-free biosensors. In this paper, we show that hybridization chain reaction (HCR) can be exploited fo ...

Integral Equation Analysis of Plane Wave Scattering by Coplanar Graphene-Strip Gratings in the THz Range

Juan Ramon Mosig, Julien Perruisseau-Carrier, Juan Sebastian Gomez Diaz

The plane wave scattering and absorption by finite and infinite gratings of free-space standing infinitely long graphene strips are studied in the THz range. A novel numerical approach, based on graphene surface impedance, hyper-singular integral equations ...

Ieee-Inst Electrical Electronics Engineers Inc2013

We study the characteristics of surface plasmons propagating along graphene sheets, focusing on the effect of spatial dispersion and applied magnetostatic bias, and taking into account the influence of the surrounding media, applied electrostatic biasing f ...

, , , ,

The construction, alignment, and performance of a setup for broadband wide-angle dispersion measurements, with emphasis on surface plasmon resonance (SPR) measurements, are presented in comprehensive detail. In contrast with most SPR instruments working wi ...

American Institute of Physics2013

Understanding and mastering the key area of CMOS biointerfaces requires a plurality of skills going beyond traditional disciplines. Indeed, biosensor design requires knowledge of biology and chemistry, surface and semiconductor technology, and electronics. ...

Beyond Scaling

Luca De Michielis

Over the recent decades, the balance between increasing the complexity of computer chips and simultaneously reducing cost per bit has been accommodated by down-scaling. While extremely successful in the past, this approach now faces grave limitations leadi ...

EPFL2012

There is a significant need for antibodies that can bind targets with greater affinity. Here we describe a. novel strategy employing chemical semisynthesis to produce symmetroadhesins: antibody-like molecules having nonprotein hinge regions that are more f ...
