AI Article Synopsis
- X-ray microscopy has advantages like deep penetration and chemical analysis through near-edge resonances.
- The study utilizes ptychography, a technique that doesn't need isolated samples, to achieve resonant imaging and distinguish between two oxygen-rich materials.
- The research includes imaging freeze-dried Deinococcus radiodurans cells to demonstrate potential applications for chemical mapping in unsliced biological samples.
Article Abstract
The unique strengths of x-ray microscopy are high penetration depth and near-edge resonances that provide chemical information. We use ptychography, a coherent diffractive imaging technique that disposes of the requirement for isolated specimens, and demonstrate resonant imaging by exploiting resonances near the oxygen K edge to differentiate between two oxygen-containing materials. To highlight a biological system where resonant ptychography might be used for chemical mapping of unsliced cells, reconstructions of freeze-dried Deinococcus radiodurans cells at an energy of 517 eV are shown.
