Merging Top-Down and Bottom-Up Approaches to Fabricate Artificial Photonic Nanomaterials with a Deterministic Electric and Magnetic Response
Artificial photonic nanomaterials made from densely packed scatterers are frequently realized either by top-down or bottom-up techniques. While top-down techniques offer unprecedented control over achievable...
PublikationenSpatiotemporal Organization of Biofilm Matrix Revealed by Confocal Raman Mapping Integrated with Non-Negative Matrix Factorization Analysis
Biofilms are microbial aggregates of microorganisms surrounded by a hydrogel-like matrix formed by extracellular polymeric substances (EPS). The formation of biofilms is intrinsically complex, from the...
PublikationenCombined Raman and AFM detection of changes in HeLa cervical cancer cells induced by CeO2 nanoparticles – molecular and morphological perspectives
The design of nanoparticles for application in medical diagnostics and therapy requires a thorough understanding of various aspects of nanoparticle–cell interactions. In this work, two unconventional...
PublikationenWater-Soluble Polymeric Carbon Nitride Colloidal Nanoparticles for Highly Selective Quasi-Homogeneous Photocatalysis
Heptazine-based polymeric carbon nitrides (PCN)are promising photocatalysts for light-driven redox transformations. However, their activity is hampered by low surface area resulting in low concentration...
PublikationenSurface characterization of nanoscale co-crystals enabled through tip enhanced Raman spectroscopy.
Atomic Force Microscopy coupled with Tip Enhanced Raman Spectroscopy (AFM-TERS) was applied to obtain information about the structure and surface composition of single nano co-crystals. For this purpose,...
PublikationenRecent advances in nano-photonic techniques for pharmaceutical drug monitoring with emphasis on Raman spectroscopy
Innovations in Raman spectroscopic techniques provide a potential solution to current problems in pharmaceutical drug monitoring. This review aims to summarize the recent advances in the field. The developments...
PublikationenBladder tissue characterization using probe-based Raman spectroscopy: Evaluation of tissue heterogeneity and influence on the model prediction
Existing approaches for early-stage bladder tumor diagnosis largely depend on invasive and time-consuming procedures, resulting in hospitalization, bleeding, bladder perforation, infection and other health...
PublikationenAntimicrobial resistance pattern and virulence profile of S. aureus isolated from household cattle and buffalo with mastitis in Egypt
Methicillin-resistant S. aureus from cows with mastitis has received a growing interest worldwide. The present study aimed to provide a detailed description of the resistance and virulence traits of isolates...
PublikationenPC-2DCOS: A Principal Component Base Approach to Two-Dimensional Correlation Spectroscopy
This paper introduces the newly developed principal component powered two-dimensional (2D) correlation spectroscopy (PC 2D-COS) as an alternative approach to 2D correlation spectroscopy taking advantage...
PublikationenUV laser induced gold nanoparticle fabrication dependent on initial film properties
The laser parameters, energy density and number of pulses, influence the UV laser-induced formation of gold nanoparticles on glass substrates. But also the deposition rate and the thickness of the gold...
