nano-FTIR reveals cell membrane penetration mechanism of enveloped virus e.g. COVID at nanoscale

Researchers from Georgia employed nano-FTIR spectroscopy and IR nanoscale imaging for investigating how individual enveloped viruses (CoV, IFV, HIV, Ebola, etc.) enter into a host cell, revealing new membrane penetration mechanisms and inhibition processes for antiviral therapies.

Ultrafast spectroscopy of electronic nano-motion in nanowires

The neaSNOM microscope equipped with a THz illumination unit were applied in ultrafast spectroscopy to take snapshots of super-fast electronic nano-motion. The scientists were able to record a 3D movie of electrons moving at the surface of a semiconductor nanowire.
