Nanocrystalline diamond SG-FET: role of grain boundaries and cell culture process
Krátká, Marie ; Kromka, Alexander ; Ukraintsev, Egor ; Brož, A. ; Kalbáčová, M. ; Rezek, Bohuslav
Fetal bovine serum layer morphology and thickness is not changing (significantly). KFM measurement show that surface potential difference between diamond and gold reduces after each process. That result indiactes changes in surface termination. FET shifts possibly related with change of diamond itself.
AFM study of FBS, BSA, Fn proteins adsorbed on H-/O-diamond
Ukraintsev, Egor ; Kromka, Alexander ; Rezek, Bohuslav
Cell growth indicates that Fibronectin is behind micro-array formation. Using AFM we measured conformations of particular proteins from Fetal bovine serum in solution and in air. AFM data are not convincing.
H-terminated diamond-capped impedance transducer: Novel molecular sensor
Stehlík, Štěpán ; Ižák, Tibor ; Kromka, Alexander ; Dolenský, B. ; Havlík, M. ; Rezek, Bohuslav
Sensitivity of an intrinsic nano-crystalline diamond (NCD) layer to naphthalene Trogers base derivative decorated with pyrrole groups(TBPyr) was characterized by impedance spectroscopy. The transducer was made of Au interdigitated electrodes (IDE) with 50um spacing on alumina substrate which were capped with the NCD layer.
Synthesis, structure, and opto-electronic properties of organic dies on diamond
Rezek, Bohuslav ; Čermák, Jan ; Ukraintsev, Egor ; Hubík, Pavel ; Mareš, Jiří J. ; Ledinský, Martin ; Fejfar, Antonín ; Kočka, Jan ; Kromka, Alexander
We prepare a thin-film heterojunction of polypyrrole (Ppy) on hydrogen-terminated diamond by electro-polymerization from solution. We combine advanced scanning techniques (AFM, KFM, micro-Raman) to characterize microscopic structural, chemical, and opto-electronic properties of such system.
