Fabrication and characterization of nonenzymatic glucose sensor based on bimetallic hollow Ag/Pt nanoparticles prepared by galvanic replacement reaction

Fig.1. Schematic of the formation of BH-Ag/Pt NPs at different stages of galvanic replacement process Daqian Ma et al., successfully fabricated a non-enzymatic glucose sensor by immobilization of bimetallic hollow Ag/Pt nanoparticles (BH-Ag/Pt NPs) using the galvanic replacement reaction onto the surface of the pretreated pure Au electrode. The morphology and composition of the BH-Ag/Pt […]

Wide-angle, broadband, and highly efficient holography

Wide-angle, broadband, and highly efficient holography

Jacob Scheuer, Yuval Yifat, Michal Eitan-Wiener, Zeev Iluz, Yael Hanein and Amir Boag Coupled dipole-patch nano-antenna cells are used in a new approach to impose an arbitrary phase profile on reflected light. 28 January 2016, SPIE Newsroom. DOI: 10.1117/2.1201512.006252 Computer-generated holography is a widely used technology for various applications, e.g., from authentication and optical data storage, to […]

Plasmonic optical tweezers: A long arm and a tight grip

Plasmonic optical tweezers: A long arm and a tight grip

  By taking advantage of the thermal gradient that is generated in plasmonic systems and by using an a.c. field, plasmonic tweezers can have a large radius of action and can trap and manipulate single nano-objects.   To have access to this paper, please visit: http://www.nature.com/nnano/journal/v11/n1/full/nnano.2015.253.html

Plasmons Enhance Detection of Wavefront Aberrations

Plasmons Enhance Detection of Wavefront Aberrations

DUBLIN, Dec. 8, 2015 — A sensor that exploits plasmonics to gauge nanoscale distortions in lightwaves could yield more powerful tools for metrology and chemical sensing, as well as sharper microscopes. The method detects wavefront aberrations indirectly by measuring changes in the reflectivity of gold films. It may be the first to use plasmons to […]

National Convention Centre, Canberra, Australia The aim of the 2016 International Conference On Nanoscience and Nanotechnology (ICONN 2016) is to bring together Australian and International communities (students, scientists, engineers and stake holders from academia, government laboratories, industry and other organisations) working in the field of nanoscale science and technology to discuss new and exciting advances […]

Infrared spectroscopy with visible light

Spectral measurements in the infrared optical range provide unique fingerprints of materials, which are useful for material analysis, environmental sensing and health diagnostics1. Current infrared spectroscopy techniques require the use of optical equipment suited for operation in the infrared range, components of which face challenges of inferior performance and high cost. Here, Kalashnikov et al. develop […]
