‘A new day for chemistry’: Molecular CT scan could dramatically speed drug discovery

Dr. Tamir Gonen, an electron crystallography expert at UCLA, teamed up with colleagues, along with Brian Stoltz at Caltech, to see whether the Gonen lab’s electron microscopy imaging methods would work with smaller organic molecules. The California team reported it worked nearly every time, delivering a resolution on par with x-ray crystallography. Scientists say the new technique could revolutionize fields both inside and outside of research.
