Cell type-specific delivery of short interfering RNAs by dye-functionalised theranostic nanoparticles
Efficient delivery of short interfering RNAs reflects a prerequisite for the development of RNA interference therapeutics. Here, we describe highly specific nanoparticles, based on near infrared fluorescent...
PublikationenA SPECTROSCOPIC APPROACH TO STUDY SEQUENCE DEPENDENT HEME-BINDING MODES IN CYSTEINE-BASED PEPTIDES AND PROTEINS
Heme (iron protoporphyrine IX) is a prosthetic group in many bacterial proteins as well as an important iron source and therefore crucial for survival and growth of bacteria. Many bacterial heme-binding...
PublikationenRefractometer based on resonance investigation of capillary cladding modes
A simple refractometer is demonstrated using a fused silica capillary spliced between two single-mode fibers. From a fundamental mode of a lead-in single-mode fiber, a number of cladding modes in the short...
PublikationenOptical breathing of nano-porous antireflective coatings through adsorption and desorption of water
We report on the direct consequences of reversible water adsorption on the optical performance of silica-based nanoporous antireflective (AR) coatings as they are applied on glass in photovoltaic and solar...
PublikationenWet-chemical passivation of anisotropic plasmonic nanoparticles for LSPR-sensing by a silica shell
Metal nanoparticles showing the effect of localized surface plasmon resonance (LSPR), a collective oscillation of the conduction electrons upon interaction with light, represent an interesting tool for...
PublikationenHigh-Capacity Directly Modulated Optical Transmitter for 2-μm Spectral Region
The 2-µm wave band is emerging as an attractive region for optical communications because of several major advantages. First of all, the Hollow-Core Photonic Band Gap Fiber (HC-PBGF), which has ultra-low...
PublikationenReflectivity and Bandwidth Modulation of Fiber Bragg Gratings in a Suspended Core Fiber by Tunable Acoustic Waves
The acousto-optic modulation of fiber Bragg gratings in a four holes suspended core fiber is experimentally demonstrated. Strong modulations with a reflectivity amplitude decrease by up to 67% and a 57%...
PublikationenOptical phonon features of triclinic montebrasite: dispersion analysis and non-polar Raman modes
Polarized infrared and Raman spectra of triclinic LiAl(PO4)(OH) [montebrasite] single crystal were recorded for appropriate optical configurations. Dispersion analysis was applied on the infrared reflectivity...
PublikationenBroadband sample holder for microwave spectroscopy of superconducting qubits
We present a practical design and implementation of a broadband sample holder suitable for microwave experiments with superconducting integrated circuits at millikelvin temperatures. Proposed design can...
PublikationenExploitation of the hepatic stellate cell Raman signature for their detection in native tissue samples
Hepatic stellate cells (HSCs) surround liver sinusoids and store retinol while they are quiescent. During fibrotic liver diseases and acute-on-chronic liver failure they change to the activated state in...
