  • Publication number: 20140147938
    Abstract: The present invention relates to a non covalent molecular structure comprising a carbon nanostructure and a pyrene based glycoconjugate (I) which is linked to the said carbon nanostructure by a non covalent link, the said glycoconjugate (I) having the formula: wherein B is a group which is present on any of the ten carbon atoms of the pyrene structure represented in (I) susceptible to bear a substituent, and is represented by the following group: —(CH2)n-CO—NH-A, wherein n is an integer from 1 to 9, A is a group of formula: The present invention also relates to an electronic device comprising the said non covalent molecular structure, and to the use of this device for the detection of a lectin involved in bacterial or viral infections. Thus the invention also relates to a method for detecting the presence of a lectin in a sample to be analysed.
