We chemically immobilized live, motile Escherichia coli on micrometer-scale, photocatalytically patterned silicon surfaces via amine- and carboxylic acid-based chemistries. Immobilization facilitated (i) controlled positioning; (ii) high resolution cell wa ...
Poly(propylene sulfide-bl-ethylene glycol) (PPS-PEG) is an amphiphilic block copolymer that spontaneously adsorbs onto gold from solution. This results in the formation of a stable polymeric layer that renders the surface protein-resistant when an appropri ...
The vacuum deposition of complex functional molecules and nanoparticles by thermal sublimation is often hindered due to their extremely low vapor pressure. This especially impedes the application of ultrahigh vacuum (UHV) based analytical and surface modif ...
Organic-inorganic hybrid coatings are becoming increasingly important due to their unique property combination [1, 2], including high optical transparency, improved scratch and abrasion resistance and excellent weathering, thanks to the synergism between t ...
It is well known in secondary ion mass spectrometry (SIMS) that sample topography leads to decreased mass resolution. Specifically, the ion's time of flight is dependent on where it was generated. Here, using matrix-enhanced SIMS, it is demonstrated that, ...
NOVELTY - The plate has electrically conductive substrate (1) that is covered with light sensitive matrix (2). The matrix comprises light absorber, charge carrier, probe molecule and photo-sensitizer (3) arranged to oxidize probe molecule by irradiation of ...
The incorporation of ceramide in phase-separated monolayers of ternary lipid mixtures has been studied by a combination of atomic force microscopy (AFM), fluorescence, and time-of-flight secondary ion mass spectrometry (ToF-SIMS). Replacement of a fraction ...
Electrospray ionisation mass spectrometry was used to analyze the reactions of metal compds. with mixts. of selected proteins. Three representative medicinally relevant compds., cisplatin, transplatin and the organometallic ruthenium compd. RAPTA-C, were r ...
The ion, beam deposition (IBD) of rhodamine dye molecules on solid surfaces in high vacuum is explored in order to characterize the possibility of fabricating molecular coatings or nanostructures from nonvolatile molecules. Molecular ion beams with a well- ...
Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) has been used to probe the interaction of the anticancer drug cisplatin with oligonucleotides. The binding kinetics, the nature of the adducts formed, and the location of the binding s ...
