borders, interdisciplinarity of nanotechnology – nanowiki #5

In the future, When Science has reached its plenitude of action, Chemistry and physics will not be but mere aspects of Molecular Mechanics. At the nanometric scale the frontiers between biology, chemistry and physics become confused And between these three A new discipline is being shaped: Nanotechnology A whole generation of scientists, capable of dealing […]

What is Nanotechnology

NANO TECHNOLOGY IS WHAT THE NEW WORLD ORDER ILLUMINATI WILL USE TO IMPLANT YOU WITH THEIR MARK TO TRACK AND CONTROL YOU… THIS IS REAL AND ALREADY BEING DONE TO SO CALLED “PSYCHIATRIC PATIENTS” ALL OVER THE UNITED STATES…. UNIVERSITY HOSPITALS LIKE THE UNIVERSITY OF LOUISVILLE HOSPITAL IN LOUISVILLE KENTUCKY ARE ALREADY IMPLANTING PEOPLE NOW […]

Wound healing assay (Fluxion Biosciences)

A wound healing assay being performed in a BioFlux microfluidic channel (Fluxion Biosciences). Wounding is created using a laminar flow stream of trypsin to cleave off cells along part of the channel. Wound response is monitored using time lapse microscopy. For more information, please see www.fluxionbio.com. Duration : 0:0:25

U type 1 hole for trapping cells

Using 3T3 cells as a model system, the motion of each individual cell was calculated using a one-way coupled Lagrangian method. The cell was assumed to be a solid sphere, and interactions with other cells were only considered when a cell sedimented in the trap. The ordinary differential equations were solved along the cell trajectory […]

cell trapping microfluidic device

Duration : 0:0:38 To investigate the dynamics of the cell trapping process, the simulated loading of the individual trapping arrays and sieve conformations was analyzed at discrete time steps. Analysis of the figure reveals that the filling of the traps at the prescribed flow rate and cell concentration 1 l /min, 5*106 cells/ml occurs quite […]

c type sieve

Duration : 0:1:0 “C-shaped sieve” shows pronounced aggregation of the cells in the downstream section of the trap. Large cell aggregates are particularly unfavorable for microscale cell culture, as they can quickly exhaust the local nutrients and reduce oxygenation efficiency, stressing the culture to the point of cell death by necrosis or apoptosis. related article: […]

cell trapping microfluidic device 2

cell loading experiment Experimental loading of PDMS microfluidic array devices with 3T3 cells. Validation of the predictive value of modeling, using 3T3 cells flowed through microfluidic devices containing U-type sieves under the simulation flow parameters, showed excellent agreement between experiment and simulation with respect to cell number per trap and the uniformity of cell distribution […]

flat type seive for trapping cells

The “flat-type sieve” consists of an array of nine sieves arranged in a symmetric diamond-shaped pattern. Under simulated conditions, sieves closer to the chamber entrances captured cells well for both geometries, while the downstream sieves remained empty. related article: Building a Better Cell Trap: Applying Lagrangian Modeling to the Design of Microfluidic Devices for Cell […]
