Time Optimization of Seed-Mediated Gold NanotriangleSynthesis Based on Kinetic Studies
The synthesis of shape-anisotropic plasmonic nanoparticles such as gold nanotriangles is of increasing interest. These particles have a high potential for applications due to their notable optical properties....
PublicationsDriving plasmonic nanoantennas at perfect impedance matching using generalized coherent perfect absorption
Coherent perfect absorption (CPA) describes the absence of all outgoing modes from a lossy resonator, driven by lossless incoming modes. Here, we show that for nanoresonators that also exhibit radiative...
PublicationsComparison of functional and discrete data analysis regimes for Raman spectra
Raman spectral data are best described by mathematical functions; however, due to the spectroscopic measurement setup, only discrete points of these functions are measured. Therefore, we investigated the...
PublicationsKinetic-Model-Free Analysis of Transient Absorption Spectra Enabled by 2D Correlation Analysis
Here, we present, to the best of our knowledge for the first time, a systematic study of utilizing 2D correlation analysis in the field of femtosecond transient absorption (fs-TA) spectroscopy. We present...
PublicationsSERS characterization of dopamine and in situ dopamine polymerization on silver nanoparticles†
Dopamine (DA) regulates several functions in the central nervous system and its depletion is responsible for psychological disorders like Parkinson’s disease. Several analytical approaches have been...
PublicationsMorpho-molecular signal correlation between optical coherence tomography and Raman spectroscopy for superior image interpretation and clinical diagnosis
The combination of manifold optical imaging modalities resulting in multimodal optical systems allows to discover a larger number of biomarkers than using a single modality. The goal of multimodal imaging...
PublicationsMonitoring Excited-State Relaxation in a Molecular Marker in live cells – a Case Study on Astaxanthin
Small molecules are frequently used as dyes, labels and markers to visualize and probe biophysical processes within cells. However, very little is generally known about the light-driven excited-state reactivity...
PublicationsControlling Growth of Poly (Triethylene Glycol Acrylate-Co-Spiropyran Acrylate) Copolymer Liquid Films on a Hydrophilic Surface by Light and Temperature
A quartz crystal microbalance with dissipation monitoring (QCM-D) was employed for in situ investigations of the effect of temperature and light on the conformational changes of a poly (triethylene glycol...
PublicationsSurface-enhanced Raman spectroscopy to characterize different fractions of extracellular vesicles from control and prostate cancer patients
Dopamine (DA) regulates several functions in the central nervous system and its depletion is responsible for psychological disorders like Parkinson’s disease. Several analytical approaches have been...
PublicationsRotation Active Sensors based on Ultrafast Fibre Lasers
Gyroscopes merit an undeniable role in inertial navigation systems, geodesy and seismology. By employing the optical Sagnac effect, ring laser gyroscopes provide exceptionally accurate measurements of...
