Liquid-Crystal and MEMS modulators for beam-shaping through multimode fibre
The previous five years have shown a rapidly growing interest in digital micromirror device (DMD) as a spatial light modulator for complex photonics applications, primarily due to their high switching...
PublicationsLaser tweezers Raman spectroscopy of E. coli under antibiotic stress in microfluidic chips
Analyzing the cells in various body fluids can greatly deepen the understanding of the mechanisms governing the cellular physiology. Because of the variability of physiological and metabolic states, it...
PublicationsNanoapertures without nanolithography
We propose and experimentally demonstrate the implementation of lithography-free nanoapertures on optical fibers. By sputtering metallic nanofilms onto the end face of step index fibers that contain central...
PublicationsCharacterization of mecC gene-carrying coagulase-negative Staphylococcus spp. isolated from various animals
The presence of the methicillin resistance gene mecC in coagulase-negative Staphylococcus spp. (CoNS) is scarce. The aim of this study was to characterize mecC-positive CoNS isolated from various wild...
PublicationsExcited-state dynamics of heteroleptic copper(I) photosensitizers and their electrochemically reduced forms containing a dipyridophenazine moiety – a spectroelectrochemical transient absorption study
The electrochemically singly-reduced Cu(I) photosensitizers of the type [Cu(xant)(N^N)]+ (with xant = xantphos ligand and N^N = bidentate diimine ligand: dipyrido[3,2-a:20,30-c]phenazine = dppz or 3,6,11,12-tetramethyl-dipyrido[3,2-a:20,30-c]phenazine...
PublicationsA novel multidrug-resistant PVL-negative CC1-MRSA-IV clone emerging in Ireland and Germany likely originated in South-Eastern Europe
This study investigated the recent emergence of multidrug-resistant Panton-Valentine leukocidin (PVL)-negative CC1-MRSA-IV in Ireland and Germany. Ten CC1-MSSA and 139 CC1-MRSA isolates recovered in Ireland...
PublicationsAll-fiber Integrated In-line Semiconductor Photoconductor
Here, we present a fully fiber-integrated semiconductor wire based photoconductor for the photodetection of light at visible and near-infrared wavelengths. The device consisting of an electrically connected...
PublicationsPredictive strength of photophysical measurements for in vitro photobiological activity in a series of Ru(II) polypyridyl complexes cerived from the π-extended ligands
This study investigates the correlation between photocytotoxicity and the prolonged excited-state lifetimes exhibited by certain Ru(II) polypyridyl photosensitizers comprised of π-expansive ligands. The...
PublicationsTransverse single-mode operation in a passive large pitch fiber with more than 200 μm mode-field diameter
In this Letter, we present, to the best of our knowledge, the largest effective single-mode fiber reported to date. The employed waveguide is a passive large pitch fiber (LPF), which 02.01.2019shows the...
PublicationsCombination of high-resolution optical coherence tomography and raman spectroscopy for improved staging and grading in bladder cancer
We present a combination of optical coherence tomography (OCT) and Raman spectroscopy (RS) for improved diagnosis and discrimination of different stages and grades of bladder cancer ex vivo by linking...
