Abstract:
Methods of modifying a nucleophilic surface of a support are described. The methods involve reacting a multifunctional electrophilic reagent with nucleophilic groups on the surface of the support. The resulting electrophilic surface can be used for the covalent attachment of particles (e.g., beads) having nucleophilic functional groups. For example, nucleic acid templates with nucleophilic (e.g., amine) groups can be attached to a surface of the particles. The nucleophilic groups on the nucleic acid templates can then be used to attach the particles to the modified surface of the support. The resulting support-bound particles can be used to analyze (e.g., sequence) the nucleic acid templates on the particles.
Abstract:
An electrically powered wheel for vehicles comprises an outer ring forming a rotor and an inner portion forming a stator; said outer ring being configured to drive the rotation of a tyre when fitted to said wheel and incorporating an arrangement of magnetic material or being constituted of magnetic material; said inner portion incorporating a powered conductive arrangement with a plurality of distinct winding portions; a connection for connecting said wheel to a controller which varies the mode of the powering of said distinct winding portions; whereby dependent upon the magnetic relationship between said magnetic material and said plurality of distinct winding portions, rotation of said outer ring is achieved, in use, whilst the inner portion remains static; wherein said wheel is configured to support the load of a vehicle.
