detection
of AIV H5N1 gene sequences using a DNA aptamer immobilized
hybrid nanomaterial-modified electrode was developed, as shown
in Fig. 1. The hybrid nanomaterial (MWNT/PPNWs/GNPs) provides
a porous structure with a large effective surface area, highly electrocatalytic
activities and electronic conductivity. In order to enhance
the recognition and selectivity of the biosensor, DNA aptamers were
used as capture probes. The results indicate that this strategy may
provide a sensitive, selective, simple, and inexpensive detection
method for the AIV genotype.
