Infrared nanospectroscopic mapping of a single metaphase chromosome

Giovanni Dietler, Andrzej Kulik, Francesco Simone Ruggeri, Ewelina Wioletta Lipiec

The integrity of the chromatin structure is essential to every process occurring within eukaryotic nuclei. However, there are no reliable tools to decipher the molecular composition of metaphase chromosomes. Here, we have applied infrared nanospectroscopy ...

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

Giovanni Dietler, Dusan Vobornik, Aleksandre Japaridze, 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 ...

Infrared nanospectroscopy characterization of oligomeric and fibrillar aggregates during amyloid formation

Giovanni Dietler, Giovanni Longo, Francesco Simone Ruggeri, Ewelina Wioletta Lipiec

Amyloids are insoluble protein fibrillar aggregates. The importance of characterizing their aggregation has steadily increased because of their link to human diseases and material science applications. In particular, misfolding and aggregation of the Josep ...
