The long-term health problems
associated with a high blood glucose level show important reduction
when diabetics can control and maintain a ‘‘normal’’ blood
glucose level. Actual technologies for glucose measurement,
mostly based on enzymes and proteins, show important limitations
in their uses [7,8]. For example, an implantable sensor for
continuous glucose monitoring is expected to find useful applications
to help diabetics. To date, none of the actual technologies
have been shown to be robust enough for the development of these
in-vivo applications. Development of new glucose sensitive materials
and new analytical approaches are still needed.
