New NIST Method Measures 3D Polymer Processing Precisely
JILA scientists have developed a fast, simple sample preparation method that enhances imaging of DNA to better analyze its physical properties and interactions.
Described in ACS Nano, JILA’s gentle, yet effective process involves binding DNA to mica, a flat silicate mineral. This process extends the DNA’s configuration—similar to expanding the bellows of an accordion—so that eight times more of the molecule can be analyzed as compared to previous methods.
