Optical Calibration of Holographic Acoustic Tweezers
Sonia Marrara, David Bronte Ciriza, Alessandro Magazzu +8
Recently, acoustic tweezers based on an array of ultrasonic transducers have been reported taking inspiration from holographic optical tweezers. In the latter technique, the calibr…
Optimal calibration of optical tweezers with arbitrary integration time and sampling frequencies -- A general framework
Laura Pérez-Garcéa, Martin Selin, Antonio Ciarlo +6
Optical tweezers (OT) have become an essential technique in several fields of physics, chemistry, and biology as precise micromanipulation tools and microscopic force transducers.…
Optically Driven Janus Micro Engine with Full Orbital Motion Control
David Bronte Ciriza, Agnese Callegari, Maria Grazia Donato +11
Microengines have shown promise for a variety of applications in nanotechnology, microfluidics and nanomedicine, including targeted drug delivery, microscale pumping, and environme…
The optical imager Galileo (OIG)
Bortoletto F., Benetti S., Bonanno G. +9
The present paper describes the construction, the installation and the operation of the Optical Imager Galileo (OIG), a scientific instrument dedicated to the 'imaging' in the visi…
Investigation of dust grains by optical tweezers for space applications
A. Magazzù, D. Bronte Ciriza, A. Musolino +10
Cosmic dust plays a dominant role in the universe, especially in the formation of stars and planetary systems. Furthermore, the surface of cosmic dust grains is the bench-work wher…
Faster and more accurate geometrical-optics optical force calculation using neural networks
David Bronte Ciriza, Alessandro Magazzù, Agnese Callegari +5
Optical forces are often calculated by discretizing the trapping light beam into a set of rays and using geometrical optics to compute the exchange of momentum. However, the number…
Optical trapping and critical Casimir forces
Agnese Callegari, Alessandro Magazzù, Andrea Gambassi +1
Critical Casimir forces emerge between objects, such as colloidal particles, whenever their surfaces spatially confine the fluctuations of the order parameter of a critical liquid…
Optical Tweezers: A Comprehensive Tutorial from Calibration to Applications
Jan Gieseler, Juan Ruben Gomez-Solano, Alessandro Magazzù +9
Since their invention in 1986 by Arthur Ashkin and colleagues, optical tweezers have become an essential tool in several fields of physics, spectroscopy, biology, nanotechnology, a…
Controlling the dynamics of colloidal particles by critical Casimir forces
Alessandro Magazzù, Agnese Callegari, Juan Pablo Staforelli +3
Critical Casimir forces can play an important role for applications in nano-science and nanotechnology, owing to their piconewton strength, nanometric action range, fine tunability…
IGR J19294+1816: a new Be-X ray binary revealed through infrared spectroscopy
J. J. Rodes-Roca, G. Bernabeu, A. Magazzù +2
The aim of this work is to characterize the counterpart to the INTEGRAL High Mass X-ray Binary candidate IGR J19294+1816 so as to establish its true nature. We obtained H band spec…
Microscopic Engine Powered by Critical Demixing
Falko Schmidt, Alessandro Magazzu, Agnese Callegari +3
By converting energy into mechanical work, engines play a central role in most biological and technological processes. In particular, within the current trend towards the developme…
