In this work, we report about optical spectrometry using gold nano-structures printed on a polymer based integrated optical waveguide. The optical waveguide is a single mode buried waveguide, having dimensions of 3x2.2μm. It is made from a combination of photo-polymerizable materials and is fabricated by photolithography on a glass substrate. To sense the electric field inside the waveguide, a ...

The development of small molecules is essential to modulate the cellular functions of biological targets in living system. Target Guided Synthesis (TGS) approaches have been used for the identification of potent small molecules for biological targets. We herein demonstrate an innovative example of TGS using DNA nano-templates that promote Huisgen cycloaddition from an array of azide and alkyne ...

Bulk gold powder (approximately 10(3) nm particle size) is a highly active catalyst for the oxidative dehydrogenation of secondary amines to imines under the mild conditions of 1 atm O2 and 60-100 degrees C.

Gold nanoparticles supported on cerium(IV) oxide powder showing strong absorption at around 550 nm due to surface plasmon resonance oxidized aromatic alcohols to corresponding aldehydes almost quantitatively in an aqueous suspension under irradiation of green light.

In this chapter, we outline protocols for assembling and characterizing peptide-gold nanoparticle conjugates. We describe two strategies for attaching peptides to gold nanoparticles. One involves the covalent coupling of cysteine-terminated peptides directly to a particle surface via a sulfur-gold bond. Alternatively, peptides are coupled to bovine serum albumin (BSA) via a bifunctional molecul...

Thanks to their unique optical and electromagnetic properties, noble-metal nanoparticles are proven very useful in many scientific fields, from nanotechnology to biology, including detection of cancer cells. Irradiated gold nanoparticles, as a nano-smolder could be widely used in biomedical contexts such as tumor therapy. Laser destruction of a cancerous tissue depends on thermal and physical p...

In Nanosciences, connecting an individual nano-object remains a technological bottleneck. The way nano-objects can be coupled to the micro and macroscopic environment without loosing their intrinsic properties is the main issue of so-called “NanoAddressing”. In LAAS-CNRS, the “Nanoaddressing/Nanobiotechnologies” group, created two years ago, develops and validate new concepts for achieving smar...

An amorphous complex precursor with uniform Mn/Ni cation distribution is attempted for preparing a nano-structured layered Li-rich oxide (Li1.2Mn0.6Ni0.2O₂)cathode material, using diethylenetriaminepentaacetic acid (DTPA) as a chelating agent. The materials are characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and electr...

The successful application of various nanoplatforms in medicine under in vitro conditions has generated some interest in medicine-nanotechnology. The spinel-type MnZn ferrite nano powders were synthesized by Solution Combustion Synthesis (SCS) method. The important classes of soft magnetic materials Mn-Zn ferrites have high magnetic permeability and low power losses.Mn-Zn-Fe2O4 have a spinal st...
