High performance fiber-Fabry-Perot resonator for quantum optics applications

Quantum optics experiments frequently require the separation of single-photon-level signals from strong classical fields. In circumstances in which the signals are spectrally close, and one cannot make...

Strawberry-like SiO2/Ag nanocomposites immersed filter paper as SERS substrate for acrylamide detection

In this work, based on the strawberry-like SiO2/Ag nanocomposites (SANC) immersed filter paper, a newly surface-enhanced Raman scattering (SERS) substrate was constructed for the detection of acrylamide...

Deep Learning for ‚Artefact‘ Removal in Infrared Spectroscopy

It has been well recognized that infrared spectra of microscopically heterogeneous media do not merely reflect the absorption of the sample but are influenced also by geometric factors and the wave nature...

Microwave-Assisted Synthesis of Core–Shell Nanoparticles—Insights into the Growth of Different Geometries

Microwave irradiation is utilized for the rapid synthesis of gold–silver core–shell bimetallic nanoparticles (NPs) in a two-step process. A strategy of establishing a bilayer organic barrier around...

Metastable atomic layer deposition: 3D self-assembly towards ultra-dark materials

Black body materials are promising candidates to meet future energy demands, as they are able to harvest energy from the total bandwidth of solar radiation. Here, we report on high-absorption near-blackbody-like...

Investigating origins of FLIm contrast in atherosclerotic lesions using combined FLIm-Raman Spectroscopy

Background: Fluorescence lifetime imaging (FLIm) is a spectroscopic imaging technique able to characterize the composition of luminal surface of arterial vessels. Studies of human coronary samples demonstrated...

Autofluorescence guided welding of heart tissue by laser pulse bursts at 1550 nm

Wound healing and other surgical technologies traditionally solved by suturing and stapling have recently been enhanced by the application of laser tissue welding. The usage of high energy laser radiation...

New Methodology to Process Shifted Excitation Raman Difference Spectroscopy Data: A Case Study of Pollen Classification

Shifted excitation Raman difference spectroscopy (SERDS) is a background correction method for Raman spectroscopy. Here, the difference spectra were directly used as input for SERDS-based classification...

Adressing differentiation in live human keratinocytes by assessment of membrane packing order

Influence of nanobody binding on fluorescence emission, mobility and organization of GFP-tagged proteins

Advanced fluorescence microscopy studies require specific and monovalent molecular labelling with bright and photostable fluorophores. This necessity led to the widespread use of fluorescently labelled...
