Conventional spontaneous Raman spectroscopy of interfacial molecules typically requires plasmonic or electronic enhancement, ...

Fiber optic SERS probes, called “optrodes,” combine spectroscopy with the flexibility and versatility of fiber optic cables. These optrodes both serve as the light carrier (the fiber) and contain the ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Rheology is the science of material flow and deformation, studying the transformation of fluids to solid-like materials and any state in between. Measurements of flow and deformation are frequently ...

The medical field is a new frontier for Raman spectroscopy. Raman has already been employed in dentistry and cancer investigations, and it is now expanding into Point-of-Care (POC) applications. This ...

At its simplest, Raman spectroscopy is a light-scattering technique. When monochromatic light, usually from a laser, hits a sample, most of it returns unchanged. But a small portion scatters ...

Laser wavelength selection, a critical determinant of accuracy and data quality, is guided by factors such as resonance, fluorescence, and sample absorption. Ensuring the correct laser wavelength ...

Graphene is a material that has a one-atom layer of carbon atoms with a thickness of only 335 pm. It can be modified using oxidization and functionalization. For example, graphene gains properties ...

Since its discovery in 2004, graphene has become a highly prized material in electronics applications owing to its unusual electronic structure. 1 Although graphene is only composed of carbon atoms, ...

Bio-monitoring refers to tracking changes in biological molecules or reactions over time. When using miniaturized flow systems, the ability to monitor concentrations within microchannels is essential ...
