Drop that Pipette: Science by Design

Drop that Pipette: Science by Design

An unexpected collaboration between a synthetic biology lab at UCSF and a Palo Alto-based design firm is stirring up the way that research is conceived and conducted, by integrating innovation and "design thinking" into the scientific method.

A Drop Pipette for Use in the Kahn Test

A quantum pipette

Curved quantum waveguides are known to bind particles. We show that a number of charged fermions in such a trap can be tuned by an external electrostatic eld; if the latter is slowly increased, the bent duct can serve as a single particle ejector.

A mechanical pipette.

An automatic pipette is a very useful equipment for any laboratory carrying out Kahn tests on a large number of sera. A number of devices were tried in a field laboratory which was functioning as a serological laboratory for the CeylonArmy Command during the years 1945 and 1946. A mechanical pipette which can easily be prepared with materials salvaged from a small workshop is described below. T...

Measurement of membrane elasticity by micro-pipette aspiration.

The classical micro-pipette aspiration technique, applied for measuring the membrane bending elasticity, is in the present work reviewed and extended to span the range of pipette aspiration pressures going through the flaccid (low pressures) to tense (high pressures) membrane regime. The quality of the conventional methods for analysing data is evaluated using numerically generated data and a n...
