tonics, as they are characterised by a high lumine- scence quantum yield and a high colour purity of the emitted light,” stresses Utochnikova.


After dissolving in solution, negatively charged europium complexes are spontaneously caught by positively charged free terminals of anchors attached to nanotubes due to electrostatic interaction. As a result, each nanotube is durably coated with mole- cules capable to emit visible light. Upon completion of the reaction, the modified nanotubes are washed and dried. The final product is a sooty powder. If the powder is, however, exposed to UV irradiation, the lanthanide complexes anchored to nanotubes start immediately to emit red light.


The concept of how to modify the nanotubes and the reagents – ionic liquid and lanthanide complex for carbon nanotube coating – has been developed in Prof. Pietraszkiewicz‘s research group at the IPC PAS, whereas the modification of nanotubes and spectral studies have been performed by research groups from the University of Namur, Belgium, and CNR-ISOF from Bolonia, Italy. The photonic mate- rial received can be used, among others, to detect molecules including those of biological importance. The identification would then take place by analysing of how the luminescence of nanotubes changes upon deposition of molecules under study thereon. Good charge conductivity combined with high lumine- scence properties make new nanotubes an attractive material also for OLED-based technologies.

Nanomaterials in Food


The NanoLyse project addresses the increasing need for analytical tools for the measurement of engi- neered nanomaterials in food. The first phase of the project focused on the procurement and characte- risation of suitable nanoparticles for use in method and reference material development.


Silver and silica nanoparticles were obtained from several commercial suppliers and the most suitable ones in terms of size, dispersibility and stability were chosen. NANOGAP’s silver nanoparticles product, NGAP NP Ag-2103, was chosen as the preferred silver material.

EU Advances the Future of Glass Applications


The ‚European forum on new glass applications‘ (Efonga) project sought to bring together the many fields active in glass working, from basic knowledge of materials to optimisation of the industrial pro- duction process. Groups involved in the EU-funded project were already operative and cooperating within the framework of the European Group of the International Commission on Glass.


One of the project‘s most important goals was to develop basic knowledge in the chemistry of glasses with a view to creating new glasses and related ap- plications, especially nano-structured glass materials.
