MagPiezo: A Magnetogenetic Platform for Remote Activation of Endogenous Piezo1 Channels in Endothelial Cells

open access: yesAdvanced Functional Materials, EarlyView.
MagPiezo enables wireless activation of endogenous Piezo1 channels without genetic modification using 19 nm magnetic nanoparticles and low‐intensity magnetic fields. It generates torque forces at the piconewton scale to trigger mechanotransduction in endothelial cells, standing as a novel platform to interrogate and manipulate Piezo1 activity in vitro.

Length Separation of Fibers

Aerosol Science and Technology, 1994
A classifier for separating conductive fibers according to length using dielectrophoresis has been developed and tested. The classifier consisted of two concentric steel cylinders with an annular space having a width of 3.18 mm. A high-voltage alternating field applied between the cylinders caused fibers to drift to the central cylinder.

Length distributions of hemoglobin S fibers

Journal of Molecular Biology, 1990
Electron microscopy of sickle cell hemoglobin fibers fixed at different times during gelation shows an exponential distribution of fiber lengths, with many short fibers and few long ones. The distribution does not change significantly with time as polymerization progresses.

BIOPERSISTENCE, FIBER LENGTH, AND CANCER RISK ASSESSMENT FOR INHALED FIBERS

Inhalation Toxicology, 2001
We briefly review the evidence that the carcinogenic risk posed by inhaled fibers depends principally on the lung burden of long fibers. We use a deposition clearance model to generate time-dependent lung burdens in rats of a dozen long fibers for various exposure concentrations.

Fiber Properties and Paper Fracture – Fiber Length and Fiber Strength

Trans. of the XIth Fund. Res. Symp. Cambridge, 1997, 1997
Phenomenological theories on the effect of pulp fiber properties on the fracture energy of paper are discussed. The effect of fiber length and strength is clarified experimentally. Fiber length appears to affect fiber failure probability only slightly. When fiber strength is changed, the fracture energy decreases greatly with only a small increment in ...
