Abstract: The present invention provides an improved capacitive bead sensor for detection and/or quantification of target analytes in a sample, with a detection limit down to single-beads, which is re-usable for multiple bead tests, or for a continuous flow of beads, and which is easily manufacturable and automatable. It enables sensitivity down to single molecule detection without the need for enzymatic amplification such as PCR, by use of various structural advantages and electronic signal amplification techniques that further allow for multiplex target detection not only across various nucleic acid targets but across entire target classes allowing for simultaneous detection of viral nucleic acids and host antibodies to that virus for example.

Abstract: A portable diagnostic device has a lysate stage (167) with a port for receiving a sample and containing magnetic beads with a probe, and an outlet port. A series of assay stages (161-164) are linked with the lysate vessel, each with a reservoir linked by channels. The final stage (164) has a sensor (169) for detecting beads attached to analyte molecules which have been conveyed according to attachment to probes on beads. Larger transport beads cause reporter beads which are tethered by target NA and probes to be transported to the final sensor stage, where they are released and detected when the transport beads have been removed.

Abstract: The invention relates to a method to encapsulate nanoparticles into a protein cage by inserting the nanoparticles into the core through holes. Currently commercially available nanoparticles can be functionalized using the inventive method. The inventive hybrids have applications in biosensing and bioimaging. The use of an affinity between poly-histidine chains and nitrilotriacetic acid as chelating reagent to obtain the inventive cages and hybrid assemblies by the method according to the invention is shown in FIG. 1.
