An innovative technology boosts image quality for protein structures

Two research teams have developed laser phase plate systems that enhance image quality in cryo-electron microscopy (cryo-EM) for protein structure determination. This advancement, detailed in a Nature publication on June 12, 2026, aims to improve the resolution and detail captured for a wide array of protein samples. Cryo-EM is a crucial technique for visualizing biological molecules at near-atomic resolution, but image quality can be limited by factors such as electron scattering and specimen drift. The new laser phase plate technology works by manipulating the phase of the electron beam, effectively correcting for aberrations and increasing the contrast in the resulting images. This could significantly benefit researchers studying complex protein assemblies, membrane proteins, and other challenging biological targets that are difficult to crystallize for traditional X-ray crystallography. The development promises to accelerate drug discovery and our understanding of fundamental biological processes by providing clearer views of molecular machinery. The researchers anticipate that this technology will become a standard tool in cryo-EM facilities, enabling more robust and reliable structural analyses.
