Conference: Insights into Hydrogen Bonded Systems: from Single Molecule to the Bulk

Speaker: Dr. Teresa Naranjo (Postdoctoral Researcher of the Photoactivated Processes Unit)

Short- bio

Teresa studied her Bachelor in Chemistry at Universidad Complutense de Madrid, UCM, at Madrid (Spain). She obtained a Master degree in Organic Chemistry from the same university in 2014. She moved to IMDEA Nanoscience, where she obtained her PhD in Organic Chemistry in 2018, under the supervision of Dr. Emilio M. Pérez. She worked on the study hydrogen-bonded supramolecular architectures taken advantage of single molecule manipulation through the Optical Tweezers technique. Currently, she works as a postdoctoral researcher in the Photoactivated Processes Unit at IMDEA Energy, thanks´ to a CAM scholarship, co-financed by the European Social Fund through the Youth Employment Operative Program and the Youth Employment Initiative (YEI).

Currently, June 2019, she is co-author of 7 papers in in peer-reviewed journals.

Summary

Supramolecular chemistry has been defined as “chemistry beyond the molecule” and focuses on the examination of the weaker and reversible noncovalent interactions between molecules. Decades after the birth of supramolecular chemistry, there are many techniques to measure noncovalent interactions in the bulk and under equilibrium conditions. As ensembles of molecules rapidly lose coherence, we cannot extrapolate bulk data to single molecule events under non-equilibrium conditions, more relevant to the dynamics of biological systems. The central topic of this talk consist on the study of supramolecular chemistry, in particular in hydrogen-bonded systems, from a single molecule point of view. For this, we have used Optical Tweezers as a single molecule manipulation technique.

On one hand, we are going to talk about the development of a new method to measure the average mechanical strength of H-bonded supramolecular complexes, at the single-molecule level, under nonequilibrium conditions.

On the other hand, we are going to talk about the mechanics and dynamics of individual molecular shuttles in aqueous conditions. Using DNA as a handle and as a single molecule reporter.
