Journal ArticleDOI
Simultaneous three-dimensional dynamic deformation measurements with pulsed digital holography
TL;DR: The three deformation components x, y, z of a vibrating object are measured simultaneously by use of digital holography with a double-pulse ruby laser source, and the shape of the object is measured by the two-wavelength contouring method.
Journal ArticleDOI
Optical tweezers based force measurement system for quantitating binding interactions: system design and application for the study of bacterial adhesion.
TL;DR: An optical force measurement system for quantitating forces in the pN range between micrometer-sized objects has been developed and has been used to measure the binding forces between Escherichia coli bacterial adhesins and galabiose-functionalized beads.
Journal ArticleDOI

TL;DR: A mathematical model of the force-versus-elongation behavior of an individual pilus has been developed and a biological model system has been established for in situ measurements of the forces that occur during mechanical stretching of pili.
Journal ArticleDOI

TL;DR: It is shown that BabA is acid responsive-binding is reduced at low pH and restored by acid neutralization, and that bio-selection and changes in BabA binding properties through mutation and recombination with babA-related genes are selected by differences among individuals and by changes in gastric acidity over time.
Journal ArticleDOI
Aberration compensation in digital holographic reconstruction of microscopic objects
TL;DR: In this paper, the authors present a method for the compensation of the aberrations appearing when a lensless hologram of a microscopic object is reconstructed using a relatively low resolution device (CCD sensor).
