At the core-facility SUSDIAM many operations of synthesis and/or processing of diamond in various forms (thin layers, suspensions, powders) are performed. The production line at the Gdańsk University of Technology enables the following processes:
- Deposition of thin electrode layers of micro- and nanocrystalline diamond doped with boron and/or nitrogen on a number of substrates (silicon, glassy carbon, titanium, quartz glass) for optoelectronic, sensory and electrochemical applications. Such electrodes are suitable for subsequent modification enabling selective sensing of a desired substance. The electrodes have already proven useful as detectors of toxins, DNA, proteins, viruses, and more.
- Preparation of suspensions of nanodiamonds. The team at the Gdańsk University of Technology specializes in creating suspensions of various nanodiamonds:
- detonation nanodiamonds without color centers: size range 5-50 nm; mean size 5 nm;
- high-pressure, high-temperature (HPHT) nanodiamonds: size range 50-1000 nm;
- conductive CVD nanodiamond powders doped by boron;
- deagglomerated HPHTor CVD nanodiamonds with nitrogen-vacancy-nitrogen centers: size range 300 nm – 1400 nm;
- Surface termination of the nanodiamonds may be controlled (oxidized, hydrogenated, carboxylated, graphitized) depending on the pre-processing performed. The range of solvents used as dispersion media includes, but is not limited to: deionized water, dimethyl sulfoxide (DMSO), isopropanol, toluene, ethanol. The concentration of the particles in the suspensions may be tuned from 100 ppm to single percents.
- Optical characterization of nanodiamond suspensions (fluorescence, particle size distributions, zeta potentia
As part of the project, was created the establishment of a robust pipeline for reliable production of NDs with narrowly definable parameters. This is be utilized within the project itself, but can be offered externally on a collaborative or pay-for-service basis to academic and commercial institutions. The Laboratory of Materials and Components Synthesis (LIME) at Gdańsk University of Technology has already gained experience in using carbon nanotechnologies in several technology-transfer-oriented projects in a manner similar to the planned project outcome. The built Core-facility is generally available to all interested customers for the supply of developed nanodiamond materials and realized customized services. All interested parties can use the Core-facility after contacting the head of facility or Centre for Knowledge and Technology Transfer Gdansk Tech. The head of the Laboratory is prof. hab. Eng. Robert Bogdanowicz.
