Statistical model on the optical properties of silicon nanowire mats
Randomly grown silicon nanowire (SiNW) mats show a high light absorption even for long wavelengths despite the small volume of silicon. We present a statistical model that gives a physical understanding...
PublikationenTwo-color Raman spectroscopy for the simultanous detection of chemotherapeutics and antioxidative status of human skin
Aiming at the development of strategies to prevent the hand-foot-syndrome, we propose evaluation of the amount of chemotherapeutics in the human skin together with carotenoids the latter serving as marker...
PublikationenSynthesis and Resonance Energy Transfer Study on a Random 2 Terpolymer Containing a 2-(Pyridine-2-yl)thiazole Donor-Type Ligand 3 and a Luminescent [Ru(bpy)2(2-(triazol-4-yl)pyridine)]2+ Chromophore
A statistical terpolymer, containing a 2-(pyridine-2-yl)-1,3-thiazole donor-type system and an acceptor-type [Ru(bpy)2-(2-(triazol-4-yl)pyridine)]2+ chromophore as well as methyl methacrylate as comonomer,...
PublikationenCharacterizing cytochrome c states – TERS studies of whole mitochondria
Protein structures (cytochrome c) were visualized by TERS measurements on whole mitochondria referring to specific spectral features describing the electronic state of the heme moiety
PublikationenLight-narrowed optically pumped Mx-magnetometer with miniaturized Cs cell
We demonstrate a new way of operating an optically pumped magnetometer with miniaturized cesium cell using the light-narrowing effect. The magnetometer setup shows improvement of shot-noise limited sensitivity...
PublikationenWavelength-dependent photoproduct formation of phycocyanobilin in solution – indications for competing reaction pathways
Phycocyanobilin (PCB), an open-chain tetrapyrrole, makes up - slightly modified - the chromophore in phytochromes, the importance of which triggered model studies on the photochemistry of free PCB. We...
PublikationenSurface enhanced Raman spectroscopy (SERS) – progress and trends
Surface enhanced Raman spectroscopy (SERS) combines molecular fingerprint specificity with potential single-molecule sensitivity. Therefore, the SERS technique is an attractive tool for sensing of molecules...
PublikationenViren mit Leitfähigkeit detektieren
Die Jenaer Biochip-Initiative hat ein chipbasiertes Verfahren entwickelt, das anders als etablierte Biochips den Gleichstromwiderstand als Messgröße nutzt. Damit lassen sich Krankheitserreger wie das...
PublikationenSingle and multilayer metamaterials fabricated by nanoimprint lithography
We demonstrate for the first time a fast and easy nanoimprint lithography (NIL) based stacking process of negative index structures like fishnet and Swiss-cross metamaterials. The process takes a few seconds,...
PublikationenDemonstration of digital readout circuit for superconducting nanowire single photon detector
We demonstrate the transfer of single photon triggered electrical pulses from a superconducting nanowire single photon detector (SNSPD) to a single flux quantum (SFQ) pulse. We describe design and test...
