TOP NANO 21”Nanostructures for Optical Devices and Elements”

Typical layerthicknesses20-100 nm

Typical linewidths50-150 nm

Optical nanostructures with line widths in the order of or less than 100 nm, and aspect ratios (linewidth / depth) of up to 1:1. Examples of application areas include anti-reflection surfaces, grating polarisersand resonant filters for application at uvand visible wavelengths.

Layer materials, thicknesses and nanostructuring are application specific

A four layer structure repeated two times gives a nice flat-top resonance effect. The grating period is 716 nm.

TOP NANO 21Nanostructures for Optical Devices and Elements

Subwavelength grating grid polariser fabricated by the slope evaporation of metal onto a replicated grating nano-structure.

Smoke detector unit: Potential application of nano-structured polariser to improve sensitivity of detector.

Anti-reflection surface - applicationof grating nanostructure to reduce the reflectivity of an optical surface.

10


TOP NANO 21Non-wetting surface coatings for precision optics

The perfluorosilanisation of smooth glass or other mainly SiO2 containing substrate surfaces results in surfaces with lowest wettability by liquids (twice lower than Teflon™) without optical losses.

The main advantage of the coatings is the strongly reduced contamination of precision optics. Cleaning efforts of optical elements is strongly reduced.

Manipulation at the nanoscale with force feedback is made accurate and easy through:

• A large workspace (∅ 300mm, which means a reduction factor of the order of 100'000)

• A force ranging from humansensitivity to 2.5kg.

High Performance Nanocrystalline Photovoltaics for Indoor Applications

This innovative photovoltaic devicewith enhanced sensitivity at low light levels uses an electroactive dye to absorb light and deliver electricity; the dye is adsorbed on a semiconductor in contact with an electrolyte, in contrast with conventional all-solid-state devices

Electrochemical photovoltaic devices maintain their conversion efficiency under low light conditions indoors where conventional solid state cells perform poorly.

16



DHM, a new instrument for cell characterisation and imaging at the nanometric scale by digital holographic microscopy

Thickness resolution of approximately 40 nanometers and a transverse resolution of 360 nm have been obtained for living cells in cultures.

DHM offers diverse and important applications in medicine and biology: diagnosis based on the non perturbing observation of living tissues and cells, and functional image of cells in culture for drug screening in pharmaceutical industry.

17



Conformation and Molecular Interaction of Proteins at Nanoscale Patterned Interfaces of Biomaterials and Biosensors

Proprietary surface chemistry in conjunction with planar wave guides adapted to the specific requirements of assay and functionality featuring extremely low non-specific binding.

High performance fluorescence imaging system and microarray-based assays with improved biological information enabled through highest sensitivity.
