Etaloning, fluorescence and ambient light suppression by modulated wavelength Raman spectroscopy
We demonstrate that wavelength modulation overcomes frequent obstacles for in situ and in vivo implementations of Raman spectroscopy, namely autofluorescence, removal of the system transmission function...
PublicationsCharacterization of atherosclerotic plaque depositions by Raman and FTIR imaging
Spectroscopy-based imaging techniques can provide useful biochemical information about tissue samples. Here, we employ Raman and Fourier transform infrared (IR) imaging to characterize composition and...
PublicationsMicro continuous flow-through synthesis of triangular silver nanoprisms and their incorporation in complexly composed polymer microparticles
The micro fluid segment technique is used for the continuous-flow synthesis for small silver nanoparticles by reduction of silver ions with sodium borohydride in aqueous solution and for the growth of...
PublicationsThe invention of immersion ultramicroscopy in 1912 – the birth of nanotechnology?
Dawn of nanotechnology: The immersion ultramicroscope was patented a century ago. When an analyte was examined with an antique instrument and with state-of-the-art technology, the historic assumptions...
PublicationsPlanar SQUID Magnetometer Integrated with Bootstrap Circuitry under Different Bias Modes
A planar Superconducting Quantum Interference Device (SQUID) magnetometer consisting of a parallel gradiometer SQUID with integrated input coils connected to an on-chip pickup loop was designed and fabricated...
PublicationsComprehensive FISH probe design tool applied to imaging human immunoglobulin class switch recombination
We present a web engine boosted fluorescence in-situ hybridization (webFISH) algorithm using a genome-wide sequence similarity search to design target-specific single-copy and repetitive DNA FISH probes....
PublicationsRSFQ electronics for controlling superconducting polarity switches
Superconducting radiation sensors are of particular interest for imaging applications in the sub-mm wavelength band because of their extraordinary sensitivity. The rising number of sensors integrated in...
PublicationsOptical properties of silicon nanowire arrays formed by metal-assisted chemical etching: evidences for light localization effect
We study the structure and optical properties of arrays of silicon nanowires (SiNWs) with mean diameter of 100 nm and length of about 1-25 µm formed on crystalline silicon (c-Si) substrates by using metal-assisted...
PublicationsSensitive and absolute absorption measurements in optical materials and coatings by laser-induced deflection technique
The laser induced deflection (LID) technique, a photo-thermal deflection setup with transversal pump-probe-beam arrangement, is applied for sensitive and absolute absorption measurements of optical materials...
PublicationsTemperature-Dependent Raman Study of the Smectic to Nematic Phase Transition and Vibrational Analysis Using Density Functional Theory of the Liquid Crystalline System 4-Decyloxy Benzoic Acid
Room-temperature Raman spectra of the thermotropic liquid crystalline system, 4-decyloxy benzoic acid (4DBA) have been recorded and the experimentally observed bands are assigned by density functional...
