Turning on hotspots: supracolloidal SERS probes made brilliant by an external activation mechanism†
We achieved external activation of local hot-spot sites in supracolloidal assembly structures. The concept was demonstrated by boosting surface-enhanced Raman scattering (SERS) efficiency by one order...
Publikationen | 13.11.2023Laboratory-Based Correlative Soft X-ray and Fluorescence Microscopy in an Integrated Setup
Correlative microscopy is a powerful technique that combines the advantages of multiple imaging modalities to achieve a comprehensive understanding of investigated samples. For example, fluorescence microscopy...
Publikationen | 13.11.2023Quantitative analysis of peroxisome tracks using a Hidden Markov Model
Diffusion and mobility are essential for cellular functions, as molecules are usually distributed throughout the cell and have to meet to interact and perform their function. This also involves the cytosolic...
Publikationen | 13.11.2023SERS-based methods for the detection of genomic biomarkers of cancer
Genomic biomarkers of cancer are based on changes in nucleic acids, which include abnormal expression levels of some miRNAs, point mutations in DNA sequences, and altered levels of DNA methylation. The...

This study aimed at investigating the chemical and mineralogical compositions of five Roman coins (four copper-based and one silver-based alloys) corrosion products, and explore the topographic and morphological...
Publikationen | 09.11.2023Ternary Łukasiewicz logic using memristive devices
Memristive devices based on the Valence Change Mechanism (VCM) are promising devices for storage class memory, neuromorphic computing and logic-in-memory (LIM) applications. They are suited for such a...
Publikationen | 09.11.2023Fast functional mapping of ligand-gated ion channels
Ligand-gated ion channels are formed by three to five subunits that control the opening of the pore in a cooperative fashion. We developed a microfluidic chip-based technique for studying ion currents...
Publikationen | 06.11.2023Integration of Passivated Gold Mirrors into Microfabricated Alkali Vapor Cells
Measurements of weak magnetic fields demand a small distance between the sensor and the to-be-measured object. Optically pumped magnetometers (OPMs) utilize laser light and the Zeeman effect in alkali...
Publikationen | 01.11.2023Low-temperature ion beam sputtered optical coatings
In thin film deposition processes, the lower limit of the deposition temperature is determined by the used coating technology and the duration of the coating process and is usually higher than room temperature....
Publikationen | 26.10.2023Mode of action of marginolactones on bacterial membranes
Azalomycin F (AzaF) is a macrolactone produced by Streptococcus spp. While its antimicrobial properties against gram-positive bacteria are known, its exact mode of action is not clear yet. This would be...
