摘要:
Provided is a method for modifying silicon with an organic molecule, under mild conditions. If the attached molecule is bi-functional, it may be subsequently reacted with a bio-molecule, to form a covalently attached layer of bio-molecule on the silicon surface.
摘要:
A porous silicon structure is stabilized by anodically oxidizing the structure and then subjecting it to chemical functionalization to protect non-oxidized surface regions, preferably in the presence of 1-decene under thermal conditions. This process creates a protective organic monolayer on the surface of the structure, rendering it highly stable.
摘要:
A method is disclosed for stabilizing porous silicon. A porous silicon structure having a surface terminated with hydrogen atoms is subjected to organic thermal processing to substitute the hydrogen atoms with a protective organic layer. The resulting structures are found to have unprecedented stability.

摘要:
The invention substantially relates to an imaging system for the chemical, biological or biochemical analysis of a sample (10), comprising a device (40) for holding the sample (10), a device (20) for optical detection, a lighting device (30), liable to emit a monochromatic light beam, and a wide aperture objective (f1), It is substantially characterized in that the objective (f1) is configured for, downstream of the sample (10): focusing the excitation light beam reflected at a point (C) located in the focal plane (FF) of said objective (f1), and transforming the retransmitted or scattered light beam into a quasi-parallel beam, and in that the system further comprises a device (70) for selectively blocking the collected light beam by said objective (f1).
摘要:
One subject of the present invention is a transparent solid support coated with at least one layer of metal and with at least one layer of transparent conductive oxide (TCO), especially tin-doped indium oxide (ITO) in order to form a solid support that can be used at the same time or independently for detection by SPR and by an electrochemical method. The invention comprises a process for producing such supports, especially by cathode sputtering using a device comprising a radiofrequency (RF) generator, this device also being included in the invention. Another subject of the invention is a kit and a method for detection or identification of an organic or mineral compound by surface plasmon resonance (SPR) and/or electrochemical plasmon resonance comprising or using such supports.
