Bacteria turn tiny gears

Swarms of bacteria turn two 380-micron long gears, opening the possibility of building hybrid biological machines at the microscopic scale.

Lipid bilayer formation

Shows the deposition of liposomes on to the surface of an optical chip and their subsequent rupture and merger to form a lipid bilayer. Protein molecules then embed and float in the surface of the bilayer. This is an excerpt from a video that iemedia solutions (http://www.iemedia.co.uk) produced for the Scientific Instrumentation Division of the […]

DNA Hydridization Fluidics Movie

DNA Hybridization CD: The final step in nucleic acid analysis is detection. Fluorescence is often used for detection, and specifically fluorescence microarrays are used when scanning for many elements at once. The Madou BioMEMS group had developed a modular, microfluidic DNA microarray/hybridization CD that allows for rapid hybridization and detection. DNA probes are spotted onto […]

Okayama University’s Artificial Muscle

DigInfo: http://movie.diginfo.tv – With the increasing elderly population who need physical istance moving around, Okayama University is working on a Mckibben Artificial Muscle system that uses air pressure to help the elderly and disabled move. The system consists of a thin mesh over a rubber tube that expands and contracts like real muscles as air […]

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 […]

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: […]

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 […]

Mystery Micro Objects #4 – UFO; Morgellons; Microchip ?

Can you help identify this object? Watch this strange unidentified object as it releases a translucent gel like hexagon from a crystal cup. These strange microscopic objects were found in skin lesions of a person who suffers from both Lyme Disease and Morgellons. She also lives directly under a flight path of a major airport […]
