In situ X-ray scattering reveals coarsening rates of superlattices self-assembled from electrostatically stabilized metal nanocrystals depend non-monotonically on driving force

Kavli Affiliate: David T. Limmer | First 5 Authors: Christian P. N. Tanner, James K. Utterback, Joshua Portner, Igor Coropceanu, Avishek Das | Summary: Self-assembly of colloidal nanocrystals (NCs) into superlattices (SLs) is an appealing strategy to design hierarchically organized materials with new functionalities. Mechanistic studies are still needed to uncover the design principles for […]

Modular DNA origami-based electrochemical detection of DNA and proteins

Kavli Affiliate: Paul W. K. Rothemund | First 5 Authors: Byoung-jin Jeon, Matteo M. Guareschi, Jaimie M. Stewart, Emily Wu, Ashwin Gopinath | Summary: The diversity and heterogeneity of biomarkers has made the development of general methods for single-step quantification of analytes difficult. For individual biomarkers, electrochemical methods that detect a conformational change in an […]
