Abstract

Sensing compositions, sensing element, sensing systems and sensing devices for the detection and/or quantitation of one or more analytes, Compositions comprising carbon nanotubes in which the carbon nanotubes retain their ability to luminesce and in which that luminescence is rendered selectively sensitive to the presence of an analyte. Compositions comprising individually dispersed carbon nanotubes, which are electronically isolated from other carbon nanotubes, yet which are associated with chemical selective species, such as polymers, particularly biological polymers, for example proteins, which can interact selectively with, or more specifically selectivity bind to, an analyte of interest. Chemically selective species bind, preferably non-covalently, to the carbon nanotube and function to provide for analyte selectivity. Chemically selective species include polymers to which one or more chemically selective groups are covalently attached. Chemically selective polymers include, for example, proteins and polysaccharides.
