Cultivation-Free Raman Spectroscopic Investigations of Bacteria
Raman spectroscopy is currently advertised as hot and ambitious technology, which brings all features to the table needed to characterize and identify bacteria. Rapidness, ease-of-use and non-invasiveness...
PublicationsGiant faraday rotation through ultra-small Fe0n clusters in superparamagnetic FeO-SiO2 vitreous films
Magneto optical (MO) glasses and, in particular, Faraday rotators are becoming key components in lasers and optical information processing, light switching, coding, filtering, and sensing. The common design...
PublicationsNanoparticle functionalised small-core suspended-core fibre – a novel platform for efficient sensing
Detecting small quantities of specific target molecules is of major importance within bioanalytics for efficient disease diagnostics. One promising sensing approach relies on combining plasmonically-active...
PublicationsCiprofloxacin: pH-dependent SERS signal and its detection in spiked river water using LoC-SERS
Monitoring the successful removal of antibiotics in waste and surface waters is of high interest to overcome the occurrence of antibacterial resistance in the ecosystem. Among the newly developed analytical...
PublicationsTrace detection of tetrahydrocannabinol (THC) with a SERS-based capillary platform prepared by the in situ microwave synthesis of AgNPs
In the present study, an ultra-sensitive and highly reproducible novel SERS-based capillary platform was developed and utilized for the trace detection of tetrahydrocannabinol (THC). The approach combines...
PublicationsRemoving image artefacts in wire array metamaterials
Hyperlenses and hyperbolic media endoscopes can overcome the diffraction limit by supporting propagating high spatial frequency extraordinary waves. While hyperlenses can resolve subwavelength details...
PublicationsTip-Enhanced Raman Spectroscopy
Tip-enhanced Raman spectroscopy (TERS), a combination of Raman spectroscopy and apertureless near-field scanning optical microscopy using a metallic tip which resonates with the local mode of the surface...
PublicationsAuto-calibration of a Lens-free Holographic Microscope With Microfluidic Chip for Medical Application
The lens-free inline holographic microscopy will be extended by the use of microfluidic chips with a total thickness up to 5.5 mm. The microfluidic chip contains an integrated pinhole mask and additional...
PublicationsThe waterfront of Karlburg and Salz in the Early and High Middle Ages – interdisciplinary (geo)archaeological and geophysical studies
For a deeper understanding of the relationship between a riverine settlement und a nearby river in the Early and High Middle Ages, some basic characteristics of inland navigation at this time have to be...
PublicationsFossata Magna – a canal contribution to harbour construction in the 1st millennium AD
Navigable canals are an exception in the 1st millennium AD in central Europe – but not as rare as often thought. Although they form key elements of the European harbour network, only a few prominent...
