Cathodoluminescence spectroscopy

STEM-CL
Understanding the localization and the interactions of biomolecules at the nanoscale and in the cellular context remains challenging. Electron microscopy (EM), unlike light-based microscopy, gives access to the cellular ultrastructure yet results in grey-scale images and averts unambiguous (co-)localization of biomolecules. Multimodal nanoparticle-based protein labels for correlative cathodoluminescence electron microscopy (CCLEM) and energy-dispersive X-ray spectromicroscopy (EDX-SM) are presented. The single-particle STEM-cathodoluminescence (CL) and characteristic X-ray emissivity of sub-20 nm lanthanide-doped nanoparticles are exploited as unique spectral fingerprints for precise label localization and identification. To maximize the nanoparticle brightness, lanthanides are incorporated in a low-phonon host lattice and separated from the environment using a passivating shell. The core/shell nanoparticles are then functionalized with either folic (terbium-doped) or caffeic acid (europium-doped). Their potential for (protein-)labeling is successfully demonstrated using HeLa cells expressing different surface receptors that bind to folic or caffeic acid, respectively. Both particle populations show single-particle CL emission along with a distinctive energy-dispersive X-ray signal, with the latter enabling color-based localization of receptors within swift imaging times well below 2 min per 2 while offering high resolution with a pixel size of 2.78 nm. Taken together, these results open a route to multi-color labeling based on electron spectromicroscopy.

About Cathodoluminescence
Attolight’s technology is based on cathodoluminescence spectroscopy technology. Cathodoluminescence (CL) is a well known phenomenon that refers to the light emitted by any material under electron irradiation. The best known cathodoluminescence application is former television sets based on cathode ray tubes. CL becomes a very powerful defect inspection method when implemented in a modern electron microscope (EM) that is capable of fast, non-destructive defect inspection on a full wafer scale. Although cathodoluminescence has been known for a long time, technical implementations have been limited to manual laboratory use.
