AFM-Based Single Molecule Techniques: Unraveling the Amyloid Pathogenic Species

Giovanni Dietler, Francesco Simone Ruggeri, Andrea Cerreta

Background: A wide class of human diseases and neurodegenerative disorders, such as Alzheimer's disease, is due to the failure of a specific peptide or protein to keep its native functional conformational state and to undergo a conformational change into a ...

Toward an Effective Control of DNA's Submolecular Conformation on a Surface

Giovanni Dietler, Aleksandre Japaridze, Dusan Vobornik, Andrea Cerreta, Ewelina Wioletta Lipiec

DNA adopts different conformations based on its environment. We reveal conditions that either preserve the DNA's physiological B-conformation, even upon its placement in UHV, or lead to a partial B-form to A-form reorganization upon DNA's deposition on a s ...

Fine DNA structure revealed by constant height frequency modulation AFM imaging

Giovanni Dietler, Dusan Vobornik, Andrea Cerreta

Few examples of sub nanometer resolution on biomolecules can be found in literature. In particular, AFM experiments on DNA mostly fail to show the double helical groove periodicity, and so far such a feat was only achieved in liquid. Here we describe a met ...

FM-AFM constant height imaging and force curves: high resolution study of DNA-tip interactions

Giovanni Dietler, Livan Bladimir Alonso Sarduy, Dusan Vobornik, Andrea Cerreta, Susana del Carmen Tobenas Borron

Interaction of the atomic force microscopy (AFM) tip with the sample can be invasive for soft samples. Frequency Modulation (FM) AFM is gentler because it allows scanning in the non-contact regime where only attractive forces exist between the tip and the ...
