High Pressure Synthesized Magnesium Diboride- and Dodecaboride-Based Superconductors: Structure and Properties

The critical current density, jc, of high-pressure synthesized MgB2-based balk materials correlates with the amount and distribution of higher borides (MgB12) and Mg-B-O inclusions, which in tern correlates...

Placenta perfusion – a suitable ex vivo model to charcterize interaction of nano-particles with human tissue?

Optical transmission through subwavelength hole arrays in ultrathin metal films

Contrary to thick opaque metal films, where an extraordinary high transmission of light is observed through subwavelength hole arrays, in ultrathin metal films perforation can lead to a suppressed or an...

Identification and characterization of single tumor cells from peripheral blood by Raman spectroscopy and optical tweezers

From Bulk to Single-Cell Classification of the Filamentous Growing Streptomyces Bacteria by Means of Raman Spectroscopy

Classification of Raman spectra recorded from single cells is commonly applied to bacteria that exhibit small sizes of approximately 1 to 2 μm. Here, we study the possibility to adopt this classification...

Online-Calibration for Reliable and Robust Lab-on-a-Chip Surface Enhanced Raman Spectroscopy Measurement in a Liquid/Liquid Segmented Flow

Concerning the usability of lab-on-a-chip surface enhanced Raman spectroscopy (LOC-SERS) for analytical tasks applying chemometric data evalutation, a secure, reproducible, and stable data output independent...

Fourier Transform Raman and DFT Study of Blue Shift C-H Stretching Vibration of Diazines on Hydrogen Bond Formation

Diazines form various types of hydrogen bonds with water, wherein C–H groups are sometimes involved directly and sometimes indirectly. On hydrogen bond formation, the wavenumber of C–H stretching vibration...

Checking and Improving Calibration of Raman Spectra using Chemometric Approaches

A wavenumber and intensity calibration procedure of Raman spectra by using chemometric techniques is presented. This approach allows the fine tuning of calibration parameters and routines with the final...

Micromanipulation of sepsis relevant bacteria with dielectrophoresis

Monitoring of monocytic host response by Raman spectroscopy
