Abstract: The present invention relates to a sensor for an electronic tongue or nose for analysing a sample or detecting a target. The sensor comprises a support, on one surface of which a plurality of sensitive areas are located, each sensitive area comprising at least one receptor and being capable of transmitting a measurable signal generated by the interaction of at least one constituent of the sample or one target with at least one receptor. The sensor is characterised in that it comprises at least three sensitive areas that differ from one another in terms of their respective receptor compositions, at least one of the sensitive areas comprising a mixture of at least two different receptors, while the two other sensitive areas each comprise at least one of the two receptors.

Abstract: This invention relates to a conjugated molecule comprising a peptide derived from the CD4 receptor coupled to an organic molecule by means of a linker as well as a process for its preparation. Said organic molecule comprises a 5 to 21 amino acid anionic polypeptide. Such a conjugated molecule can be used in antiviral treatment, namely in the treatment of AIDS.

Abstract: The present invention relates to an activated peptide derived from the CD4 receptor, which is capable of coupling by covalent bonding to an organic molecule and thus makes it possible to generate multiple potentially antiviral derivatives. The present invention also relates to a conjugated molecule comprising the CD4-receptor-derived peptide and an organic molecule, preferably the GPR1 peptide or a polyanion. Such a conjugated molecule can in particular be used in antiviral treatments, in particular the treatment of AIDS. The invention also relates to the methods for preparing the activated peptide derived from the CD4 receptor and the conjugated molecule.
