In this paper we use force spectroscopy to characterize the thermodynamics, kinetics and selectivity of binding of an anticancer peptide bis-intercalating DNA. We find that the kinetics of bis-intercalation are very slow (hours) and strongly force-dependent showing the existence of a mono-intercalated intermediate state that remained elusive until now. Binding selectivity is demonstrated through a novel single-molecule footprinting assay that provides rapid access to the sequence-selectivity of small ligands with one base pair resolution.

**Review articles**

### • F. Ritort, *The noisy and marvelous molecular world of biology*, Inventions 4, 24 (2019). At the molecular level biology is intrinsically noisy. The forces regulating the myriad of molecular reactions in a cell are tiny, on the order of piconewtons, yet they proceed in concerted action making life possible. This mini-review describes the role played by energy and physical information in biology from a personal biophysical perspective. The article is written in memoriam of Jorge Wagensberg, physics professor at the University of Barcelona, who passed away on the 3rd March 2018 at the age of 69. Wagensberg was an inspiring scientist and philosopher who saw in science and art the beauty of nature and knowledge. His love for all expressions of intellectual mankind will remain as a source of inspiration and legacy to future generations of scientists.

### • F. Ritort, *Pinzas ópticas y su aplicación a sistemas biológicos*, Revista Española de Física Vol 32, No 4 (2018). The 2018 Nobel Prize for Physics was awarded “for groundbreaking inventions in the field of laser physics” to Arthur Ashkin (1/2 of the prize), Donna Strickland and Gérard Mourou (who together shared the other 1/2). This review (written in spanish) focuses on the work of Arthur Ashkin – the oldest living Nobel laureate! – who got the prize for the invention of Optical Tweezers.The tweezers turned out to a fabulous tool for manipulating small objects and performing quantitative measurements on them. They have been used in particular in the field of biophysics to measure mechanical properties of DNA, RNA and proteins and from these measurements we have learnt a lot how these molecules of life work, but there is a lot yet to be explored!

### • J. Camunas-Soler, M. Ribezzi-Crivellari and F. Ritort, *Elastic properties of nucleic acids by single-molecule force spectroscopy*, Annual Review of Biophysics, vol. 45, 65-84 (2016). We review the current knowledge on the use of single-molecule force spectroscopy techniques to extrapolate the elastic properties of nucleic acids. We emphasize the lesser-known elastic properties of single-stranded DNA. We discuss the importance of accurately determining the elastic response in pulling experiments, and we review the simplest models used to rationalize the experimental data as well as the experimental approaches used to pull single-stranded DNA. Applications used to investigate DNA conformational transitions and secondary structure formation are also highlighted. Finally, we provide an overview of the effects of salt and temperature and briefly discuss the effects of contour length and sequence dependence.

Special emphasis is placed on single-molecule experiments and their contribution to expanding our current understanding of fundamental concepts, such as temperature, energy, entropy, and information

After briefly reminding key concepts about free energy measurements and calculations we discuss issues concerning the correct definition of mechanical work, the non-Galilean invariance of fluctuation theorems and free energy recovery from unidirectional work measurement.

### • A. Alemany and F. Ritort, *Fluctuation theorems in small systems: extending thermodynamics to the nanoscale*, Europhysics News, vol. 41, 27-30 (2010). Single molecule experiments make it possible to resolve energy processes with unprecedented detail at the level of 1 kBT, the typical energy scale of Brownian fluctuations. This is a very concise review about fluctuation theorems and the application to obtain equilibrium information from non-equilibrium experiments.

### • F. Ritort, *Fluctuations in open systems*, Physics, vol. 2, 43 (2009). Small nonequilibrium systems behave quite unexpectedly when in contact with a thermal reservoir. However, all of them, from molecular machines to molecular magnets, are described by a single fluctuation theorem.

Ritort, *Investigating the thermodynamics of small biosystems with optical tweezers*, Physica E (Low-dimensional Systems and Nanostructures), doi:10.1016/j.physe.2009.06.055. We present two examples of how single-molecule experimental techniques applied to biological systems can give insight into problems within the scope of equilibrium and nonequilibrium mesoscopic thermodynamics. The first example is the mapping of the free energy landscape of a macromolecule, the second the experimental verification of Crooks fluctuation theorem. In both cases the experimental setup comprises optical tweezers and DNA molecules.

Ritort, *The nonequilibrium thermodynamics of small systems*, Comptes Rendus Physique,8 (2007) 528-539.Nonequilibrium thermodynamics of small systems describes energy exchange processes between a system and its environment in the low energy range of a few kBT where Brownian fluctuations are dominant. In this article I discuss some aspects about fluctuation theorems and path thermodynamics that call for the necessity of a better understanding of large deviations in nonequilibrium statistical physics. I also emphasize how single molecule experiments are a valuable source of knowledge and information that can greatly contribute to the unveiling of the most important and relevant questions in this exciting field of research.
