An assessment of the resolution limitation due to radiation-damage in x-ray diffraction microscopy

open access: yes, 2005
X-ray diffraction microscopy (XDM) is a new form of x-ray imaging that is being practiced at several third-generation synchrotron-radiation x-ray facilities.

Opsin vs opsin: new materials for biotechnological applications

open access: yes, 2014
The need of new diagnostic methods satisfying, as an early detection, a low invasive procedure and a cost-efficient value, is orienting the technological research toward the use of bio-integrated devices, in particular bio-sensors.

Lipidic cubic phase injector is a viable crystal delivery system for time-resolved serial crystallography

open access: yesNature Communications, 2016
Serial femtosecond crystallography using X-ray free-electron lasers has huge potential for time-resolved structural experiments. Here, the authors present a structure of the light-driven proton pump bacteriorhodopsin using these techniques.

Excited-state dynamics of bacteriorhodopsin

open access: yesBiophysical Journal, 1985
Near infrared emission of bacteriorhodopsin at neutral pH and at room temperature was characterized by a large Stokes shift. This characteristic was lost in an acidic pH (approximately pH 2) where a remarkable enchancement (more than 10 times) in the fluorescence quantum yield accompanied the red shift in the main absorption band.

Mixed Potential Energy Surfaces of the Ultrafast Isomerization of Retinal in Bacteriorhodopsin

open access: yesEPJ Web of Conferences, 2013
We observe, using electronic two-dimensional photon echo spectroscopy, that the cis and trans potential energy surfaces of the ultrafast isomerization of retinal in bacteriorhodopsin are mixed via the hydrogen out of plane (HOOP) mode.

Dynamics of active membranes with internal noise

open access: yes, 2005
We study the time-dependent height fluctuations of an active membrane containing energy-dissipating pumps that drive the membrane out of equilibrium.
