Cell migration is a fundamental property of all animal cells which is involved in processes such as embryogenesis, immune response, tissue regeneration and cancer metastasis. Directional migration requires cell polarization which could happen in response t ...
Combination of glass nanocapillaries with optical tweezers allowed us to detect DNA-protein complexes in physiological conditions. In this system, a protein bound to DNA is characterized by a simultaneous change of the force and ionic current signals from ...
The first practical, portable “dynamometer”, designed in 1798 by Regnier, was used to quantify the muscular strength of men and animals. It was promptly used by ethnologists to test the strength of the “savages”. A smaller improved model (Collin dynamomete ...
We propose to control the motion of nanoparticles using phase-gradient metasurfaces. The latter are used to generate surface waves, which put the particles into motion, when illuminated by a normally incident plane wave. We present an initial study of the ...
Recent advances in remote powering and telemetry permitted the use of sensors inside body. A few studies have been already done on smart knee prostheses, but all focused on monitoring the in-vivo contact forces and moments. A smart design, compatible with ...
In Italy, biomechanics research and the analysis of human and animal movement have had a very long history, beginning with the exceptional pioneering work of Leonardo da Vinci. In 1489, da Vinci began investigating human anatomy, including an examination o ...
The Bell-Evans model which predicts the linear dependence of the most probable intermolecular bond rupture force on the logarithm of stretching force loading rate is usually used to discuss the dynamic force spectroscopy experiment data. This model is cons ...
The present invention related to an optical force sensing element for microsurgical instruments (22), for measuring force F in three orthogonal directions x, y, z, comprising a monolithic cylinder structure (1), a cylindrical surface (4) and a top surface ...
Besides their excellent dielectric and thermo-mechanical characteristics Low Temperature Cofiring Ceramics (LTCC) are also well suited for the fabrication of 3D micromechanical components such as sensors for mechanical quantities. This paper describes the ...
