In the second project, long capture probe similar to the first project was applied in a CVD graphene-based biosensor. Here, a secondary reporter probe with gold nano-particles conjugated with target complementary oligonucleotide was applied. The reporter probe enhanced the sensitivity of the biosensor and the detection limit was as low as 64 fM. More importantly, it has the ability to differentiate single-base mismatch from fully complementary sequence which suggested an excellent specificity. In the final chapter, a reduced graphene oxide-based electrochemical biosensor was developed for sensing botulinum neurotoxin type A. An artificially synthesized recognition probe (SNAP-25-GFP) with cleavage site for botulinum neurotoxin type A was immobilized on the surface of reduced graphene oxide. Initially, the electrode surface was covered making it inaccessible to the redox probe in the standard buffer. When botulinum neurotoxin type A presented in the analyte, the probe on the surface of reduced graphene oxide was removed exposing the electrode, thus recovering the electrochemical signal. This sensing system demonstrated a very good limit of detection against botulinum neurotoxin A with excellent specificity, which only fresh and active botulinum neurotoxin A can be detected. More importantly, this electrochemical-sensing platform was proved to be functioning when botulinum neurotoxin A dispersed in milk, mimicking a real-life sample. The low interference suggested its potential to be applied as an on-site toxin screening platform.
