Different microstructures were created on the surface of a polycrystalline diamond plate (obtained by microwave plasma-enhanced chemical vapor deposition—MW PECVD process) by use of a nanosecond pulsed DPSS (diode pumped solid state) laser with a 355 nm wavelength and a galvanometer scanning system. Different average powers (5 to 11 W), scanning speeds (50 to 400 mm/s) and scan line spacings (“hatch spacing”) (5 to 20 µm) were applied. The microstructures were then examined using scanning electron microscopy, confocal microscopy and Raman spectroscopy techniques. Microstructures exhibiting excellent geometry were obtained. The precise geometries of the microstructures, exhibiting good perpendicularity, deep channels and smooth surfaces show that the laser microprocessing can be applied in manufacturing diamond microfluidic devices. Raman spectra show small differences depending on the process parameters used. In some cases, the diamond band (at 1332 cm−1) after laser modification of material is only slightly wider and shifted, but with no additional peaks, indicating that the diamond is almost not changed after laser interaction. Some parameters did show that the modification of material had occurred and additional peaks in Raman spectra (typical for low-quality chemical vapor deposition CVD diamond) appeared, indicating the growing disorder of material or manufacturing of the new carbon phase.

Diamond is increasingly used in biomedical applications because of its unique properties such as the highest thermal conductivity, good optical properties, high electrical breakdown voltage as well as excellent biocompatibility and chemical resistance. Diamond has also been introduced as an excellent substrate to make the functional microchip structures for electrophoresis, which is the most popular separation technique for the determination of analytes. In this investigation, a diamond electrophoretic chip was manufactured by a replica method using a silicon mold. A polycrystalline 300 micron-thick diamond layer was grown by the microwave plasma-assisted CVD (MPCVD) technique onto a patterned silicon substrate followed by the removal of the substrate. The geometry of microstructure, chemical composition, thermal and optical properties of the resulting free-standing diamond electrophoretic microchip structure were examined by CLSM, SFE, UV-Vis, Raman, XRD and X-ray Photoelectron Spectroscopy, and by a modified laser flash method for thermal property measurements.

In this paper Raman spectra of diamonds from two different ureilites, JaH 054 and Sahara 98505, were measured. Obtained results for both ureilites showed the Raman shift ranged between 1321 cm −1 and 1336 cm −1 for JaH 054 and between 1329 cm −1 and 1336 cm −1 for Sahara 98505. FWHM parameter (full width at half maximum) varied also in wide range especially for Sahara 98505. Raman imaging was done for JaH 054 sample and diamonds of different Raman shifts ( 1321 cm −1 , 1328 cm −1 , 1330 cm −1 ) were found in few tens μm sized area of carbon vein. Raman peaks of ureilitic diamonds were compared with literature data of laboratory diamonds produced under high pressure, under low pressure with MW PACVD method and with other ureilites. Presented research showed that even in highly shocked ureilites Raman shift versus FWHM parameter plots are similar with CVD diamonds for ureilites. However, the origin of diamonds in ureilites is not explained based on the obtained results, close coexistence of different diamonds in investigated ureilites suggests that the mechanism of diamond creation in meteorites was very complex and could be multi‐step process.

We have studied the Raman spectroscopic signatures of nanodiamonds from the Allende meteorite in which some portions must be of presolar origin as indicated by the isotopic compositions of various trace elements. The spectra of the meteoritic nanodiamond show a narrow peak at 1326 cm−1 and a broad band at 1590 cm−1. Compared to the intensities of these peaks, the background fluorescence is relatively high. A significant frequency shift from 1332 to 1326 cm−1, peak broadening, and appearance of a new peak at 1590 cm−1 might be due to shock effects during formation of the diamond grains. Such changes may have several origins: an increase in bond length, a change in the electron density function or charge transfer, or a combination of these factors. However, Raman spectroscopy alone does not allow distinguishing between a shock origin of the nanodiamonds and formation by a CVD process as is favored by most workers.

An artificial heart valve ring made of titanium alloy Ti6Al4V was coated with nanocrystalline diamond (NCD) with the use of RF PACVD technique. Then the heart valve with NCD coating and Derlin disc was tested by means of a long-term mechanical fatigue examination in a home-designed apparatus manufactured at the Technical University of Lodz (Poland). Before and after the mechanical fatigue experiments, the surface of the valve ring was examined by Scanning Electron Microscopy (SEM) and by Raman Spectroscopy. The investigations verified the good quality of the coating covering all the surfaces, even in the most critical points where plasma didn't penetrate well during the coating deposition. Moreover, the comparison of studies before and after mechanical fatigue experiments show that the surface after the experiments is in good condition, still tight, and the range of the NCD layer thickness is the same as before the operation. The Raman spectra indicate that the NCD coating still covers all the surface of the ring (even in the places of the disc–ring interaction during relative motion of the disc).

The confocal Raman micro-spectroscopy was used for extraterrestrial carbonaceous matter characterisation. Different allotropic forms of carbon, mainly graphite and lonsdaleite, were identified in various meteorites: ordinary chondrites DaG 610 and NWA 869, in NWA 3118 carbonaceous chondrite, and in iron meteorites Morasko and in Sikhote Alin.

The investigations presented here focus on optimization of DNA microfluidic devices. Different wide bandgap materials such as diamond, Al2O3, polymer (polydimethylsiloxane) and quartz are compared with regard to optical and electrical properties, bioinertness and heat transfer. Different phenomena occurring during capillary electrophoretic separations are taken into consideration. The advantages and drawbacks of using different materials are discussed taking into consideration technological possibilities of manufacturing microstructures and economical aspects.
