Abstract: Methods, systems, and apparatuses for extracting non-polar lipids from microalgae are achieved using a lipid extraction device having an anode and a cathode that forms a channel and defines a fluid flow path through which an aqueous slurry is passed. An electromotive force is applied across the channel at a gap distance in a range from 0 5 mm to 200 mm to cause the non-polar lipids to be released from the algae cells. The non-polar lipids can be extracted at a high throughput rate and with low concentrations of polar lipids such as phospholipids and chlorophyll.

An internal pipe (4) that forms, together with the chamber wall, an annular gap (12) through which the fluid flows is arranged in the chamber (2). A supply valve (20) is located upstream of or at, the fluid inlet, and an outlet valve (30, 40) is provided at the particle outlet. At least one magnet (14, 36) is arranged outside said annular gap, between the fluid inlet and the cleaned fluid outlet in the direction of flow. A rotatable, helical scraper (10) is located in the annular gap (12), which scraper transports magnetizable particles which have deposited on the chamber wall and/or the internal pipe to the particle outlet (28, 38).

Abstract: A microfluidic device for separating target components from a source fluid includes one or more source channels connected to one or more collection channels by one or more transfer channels. The target components of the source fluid can be magnetic or bound to magnetic particles using a know binding agent. A source fluid containing magnetically bound target components can be pumped through the source channel of the microfluidic device. A magnetic field gradient can be applied to the source fluid in the source channel causing the magnetically bound target components to migrate through the transfer channel into the collection channel. The collection channel can include a collection fluid that is stagnant until a predefined volume of source fluid is processed or a predefined volume of target components accumulate in the collection channel, at which point collection fluid can be pumped into the collection channel to flush the target components out of the collection channel. The target components can be subsequently analyzed for detection and diagnosis.
