Abstract: The present invention relates to a protein receptacle capable of receiving several exogenous polyamino acid sequences, concomitantly, for expression in various systems and for different uses. The present invention relates to polynucleotides capable of generating the aforementioned protein receptacle. The present invention also relates to vector and expression cassette comprising the aforementioned polynucleotide. The present invention further relates to the cell comprising the aforementioned expression vector or cassette. The present invention further relates to a method for producing said protein receptacle and for pathogen identification or disease diagnosis in vitro. The present invention further relates to the use of said protein receptacle and kit comprising said protein receptacle for diagnostic purposes or as vaccine compositions.

Abstract: The application describes a biosensor system to measure the presence of single molecules of interest or multiple molecules simultaneously in aqueous solutions without the need for trained personnel or dedicated laboratory space. The system uses a lab-on-a-chip platform to contain and manipulate a biosensor component that, through a series of controlled steps, converts the presence of each of the molecule/s of interest into a unique nucleic acid identifier designated by a specific sequence. The generation of the unique nucleic acid identifier is strictly correlated with the presence of the molecule of interest. The platform contains: multiple, sequential, interconnected chambers; transformer coils that induce magnetic fields; the potential for various electric fields; thermal controls; electronics for measurements; and power control.
