Lens-free inline holographic microscopy with numerical correction of layers with different refractive index
Digital inline holographic microscopy is applied for lens-free imaging with high lateral resolution. Microfluidic chambers for imaging of cells in water-like or native solutions, e.g. thick layers of glass...
PublikationenBlood cell diagnostics by a chip lensless microscope
We present the digital inline holographic microscopy for blood cell counting. The microscope unit contains a pinhole chip for illumination, a micro-fluidic chip, and a CMOS-chip for detection. The design...
PublikationenPhase dynamics of two parallel stacks of coupled Josephson junctions
Two parallel stacks of coupled Josephson junctions (JJs) are investigated to clarify the physics of transitions between the rotating and oscillating states and their effect on the IV-characteristics of...
PublikationenMembrane based thermoelectric sensor array for space debris detection
As manmade space debris in the low earth orbit becomes an increasing risk to space missions, which could even result in total mission loss, it has become even more critical to have detailed knowledge of...
PublikationenKRAS mutation screening by chip-based DNA hybridization – a further step towards personalized oncology
The use of predictive biomarkers can help to improve therapeutic options for the individual cancerpatient. For the treatment of colon cancer patients with anti-EGFR-based drugs, the KRAS mutation statushas...
PublikationenDroplet based microfluidics: spectroscopic characterization of Levofloxacin and its SERS detection
Levofloxacin (Levo), a second generation fluoroquinolone, has both clinical and environmental relevance. Therefore, the implementation of fast, robust and cost effective techniques for its monitoring is...
PublikationenRaman-Mikrospektroskopie für eine schnelle Erregerdiagnostik
Viele Applikationsfelder in der Lebensmittelindustrie erfordern eine schnelle und zuverlässige Identifizierung pathogener Keime. Die Raman-Spektroskopie als sensitive und hochspezifische Nachweismethode...
PublikationenAqueous Black Colloids of Reticular Nanostructured Gold
Since ancient times, noble gold has continuously contributed to several aspects of life from medicine to electronics. It perpetually reveals its new features. We report the finding of a unique form of...
PublikationenPalladium versus Platin – Das Metall im Katalysezentrum eines molekularen Photokatalysators bestimmt den Mechanismus der Wasserstoffproduktion mit sichtbarem Licht
To develop highly efficient molecular photocatalysts for visible light-driven hydrogen production, a thorough understanding of the photophysical and chemical processes in the photocatalyst is of vital...
PublikationenHole injection dynamics from two structurally related Ru–bipyridine complexes into NiOx is determined by the substitution pattern of the ligands
The dyes bis[2,2'-bipyridine][4,4'-dicarboxy-2,2'-bipyridine]ruthenium(II) dihexafluorophosphate, [Ru(bpy)2dcb](PF6)2 (Ru1) and tris(4,4'-bis(ethylcarboxy)-2,2'-bipyridine)ruthenium(II) dihexafluorophosphate,...
