We propose a technology that will sit at the front-end of sequencing pipelines, present and future, and will significantly enhance the quality and throughput of DNA sequencing. Although much attention has been given to throughput/cost of the sequencing process itself, the same cannot be said for the preparation of samples. Identified bottlenecks are (1) sequencing technologies require days of upfront sample preparation which is further increased when sequencing selected parts of the genome; (2) genome assembly relies on computationally intensive comparisons to the reference genome because existing technologies produce short sequence reads; (3) it is difficult to begin with small amounts of sample material comprising micro-biopsies and single cells. The CELL-O-MATIC project will synergize efforts from SMEs, academics and large companies to address these bottlenecks by developing chip-based systems that process DNA from individual cells, ready for next generation high-throughput sequencing. Single cell analysis has numerous applications in systems biology but we will emphasize DNA isolation and sequencing from circulating tumor cells (CTC), which have a strong prognostic value in cancer management. A second innovation will be to develop methods that enable up to whole chromosome lengths of DNA to be contiguously mapped using nanofluidics. The inclusion of nanofluidics makes the project particularly distinctive and introduces European SMEs to an area that so far has been the domain of US companies. A modular prototype comprising, a chip, fluid and thermal control, sonication and optical detection will be developed. Samples prepared using CELL-O-MATIC technology will be benchmarked in a high throughput environment with samples prepared by existing methods. Finally, the information obtained from the CELL-O-MATIC processed sample material will be validated for its utility as an aid to clinical decision making.


There is provided a method and device for measuring an ion concentration of a sample. The method comprises exposing a chemical sensor to the sample to provide an electrical output signal 5 representing said ion concentration and controlling a titrator exposed to the sample to release or absorb a quantity of ions to the sample. The method may use feedback means comprising Pulse Width Modulation control to drive the titrator such that the sample maintains a stable ion concentration.

Patent
DNA Electronics Ltd. | Date: 2013-03-28

A plug side surface of a plug housing is provided with a claw portion. The claw portion includes a plug lock surface facing in a direction away from a connector mounting surface. Each assistant fitting of a receptacle connector includes a receptacle lock surface that faces in a direction approaching the connector mounting surface and is opposed to the plug lock surface in a mated state. The plug lock surface includes a lock maintaining surface and an unlocking surface. Assuming that an angle formed between a reference plane and the lock maintaining surface is a lock maintaining angle and an angle formed between the reference plane and the unlocking surface is an unlocking angle, the lock maintaining angle is smaller than the unlocking angle.

Patent
DNA Electronics Inc. | Date: 2016-07-11

The invention generally relates to using magnetic particles and alternating magnet fields to separate a target analyte from a sample. In certain embodiments, methods of the invention involve contacting a sample with magnetic particles including first moieties specific for a target analyte, thereby forming target/particle complexes in the sample, flowing the sample through a channel including second moieties attached to at least one surface of the channel, applying alternating magnetic fields to the flowing sample to result in target/particle complexes being brought into proximity of the surface to bind the second moieties and unbound particles remaining free in the sample, binding the target/particle complexes to the second moieties, and washing away unbound particles and unbound analytes of the sample.

A device for sensing a property of a fluid comprising a first substrate having formed thereon a sensor configured in use to come into contact with a fluid in order to sense a property of the fluid, and a wireless transmitter for transmitting data over a wireless data link and a second substrate having formed thereon a wireless receiver for receiving data transmitted over said wireless link by said wireless transmitter. The first substrate is fixed to or within said second substrate. Additionally or alternatively, the device comprises a first substrate defining one or more microfluidic structures for receiving a fluid to be sensed and a second substrate comprising or having attached thereto a multiplicity of fluid sensors, the number of sensors being greater than the number of microfluidic structures. The second substrate is in contact with the first substrate such that at least one of the sensors is aligned with the or each microfluidic structure so as to provide an active sensor for the or each structure, and such that one or more of the sensors is or are not aligned with any microfluidic structure and is or are thereby redundant.
