Atomic force microscopy (AFM) was performed in PeakForce QNM mode using a multimode AFM (Brüker) with a NanoScope V controller and silicon probes (resonance frequency of 50–90 Hz and spring constant of ~0.4 N/m). Based on obtained height micrographs of PDMS-r-PEG brushes deposited...
(emission wavelength 530 nm) and 540 nm for dead cells (emission wavelength 618 nm). Subsequently, the target HeLa cell was cultured inside the microgripper’s bucket for an additional 4 h. A second manipulation was then performed to transport the HeLa cell along a rectangular ...

The dashed grey line in c and d at 310 nm indicates the wavelength used for tracing the reaction kinetics. All Spectra were normalized to a maximum absorbance of one arbitrary unit (AU) Full size image The reaction between DHBQ and ClO2 at pH 3 was generally fast. A tenfold excess of ...

Time-frequency analysis of functional optical mammographic images Simultaneous dual-wavelength studies were performed at 760 and 830 nm at a framing rate of ~2.7 Hz. Optical measures were performed on women lying prone... RL Barbour,HL Graber,CH Schmitz,... - Proceedings of SPIE - The Internat...
Hence, the cells inside the islet are still excitable like in our present simulations, but the whole islet oscillates with the frequency of the wave emission from the edges (the results hold for the three-dimensional geometry as well). These results will be published elsewhere. Note that our ...
As can be seen, the diameter of semicircle in the high-medium-frequency region for all samples is reduced after 20 cycles, suggesting the charge transfer become easier. The improved impedance characteristics of the SSHC electrode are attributed to the maintenance of its structure and the enhanced...
analyzed using monochromatic electromagnetic radiation in the UV and visible ranges at a wavelength of 585 nm. The solution’s pH has a considerable effect on the adsorption procedure. The impact of solution pH on dye adsorption was studied while maintaining a constant temperature and a constant ...
Using a 100 × objective with a 0.9 numerical aperture at 638 nm laser excitation wavelength, a laser beam of ~ 11 mW was focused to a spot area of ~ 1 µm2. Raman spectra were collected per sample from 100 to 3000 cm−1 with an acquisition time of 10 s and five...
