Combined 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...

Molecular characterisation of extended-spectrum β-lactamase (ESBL) producing Escherichia coli in wild birds and cattle, Ibadan, Nigeria

Hollow microsphere combined with optical harmonic Vernier effect for strain and temperature discrimination

Achieving a new generation of enhanced sensors requires the development of structures that result from the fusion of different concepts and effects. In this paper, we combine a special strain sensing structure...

Beyond Beer’s law: Spectral Mixing Rules

Based on Beer’s law, it is assumed that the absorbance of a mixture is that of the neat materials weighted by their relative amounts (linear mixing rule). In this contribution, we show that this is an...

A virtual “Werkstatt” for digitization in the sciences

Data is central in almost all scientific disciplines nowadays. Furthermore, intelligent systems have developed rapidly in recent years, so that in many disciplines the expectation is emerging that with...

DNA-Biofunctionalization of CTAC-capped gold nanocubes

Clinical diagnostics and disease control are fields that strongly depend on technologies for rapid, sensitive, and selective detection of biological or chemical analytes. Nanoparticles have become an integral...

Effects of small crystallite size on the thermal infrared (vibrational) spectra of minerals

The thermal infrared (TIR, or vibrational) emission spectra of a suite of synthetic Mg-Fe olivines exhibit notable differences from their natural igneous counterparts in terms of their band shapes, relative...

Influence of adhesion intermediate layers on the stability of nanodiamond composite films deposited on Si substrates by coaxial arc plasma

Nanodiamond composite (NDC) films deposited on silicon substrates by coaxial-arc-plasma-deposition at room temperature are easily peeled off with increasing film thickness. This research adapted additional...

Comparison of standard and HD FT-IR with multimodal CARS/TPEF/SHG/FLIMS imaging in the detection of the early stage of pulmonary metastasis of murine breast cancer

Lungs, due to their high oxygen availability and vascularization, are an ideal environment for cancer cell migration, metastasis and tumour formation. These processes are directly connected with extracellular...

Surface 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,...
