Electron microscopy (EM) has been used for over 70 years in biological research, from tissue and cell ultrastructure down to the molecular organisation of proteins and macromolecules. EM is often used in combination with a variety of additional techniques, in the hope of linking structure to function and gaining a better understanding of life science specimens. Oxford Instruments NanoAnalysis provides tools, cameras, and analytical systems that are optimised for applications in life sciences, improving sensitivity, increasing throughput, and changing how we interpret biological information from the basic units of life through to complex medical research.
Energy Dispersive X-ray Spectrosmetry (EDS) is opening new dimensions for biological electron microscopy, adding compositional information (colour EM) to greyscale ultrastructural images in SEM and TEM. The additional elemental information can be used for a variety of applications including, but not restricted to, measuring the quantity and localising endogenous biological elements, imaging ultrastructure without any stain in resin-embedded and cryo-specimens, investigating the location and distribution of nanoparticles in cells and tissues, determining ion gradients across specified areas, investigating the composition of pollutants or contamination of biological material and the identification of a diverse range of stains and immunolabels.
