Enhancing graphene/CNT based electrochemical detection using magneto-nanobioprobes
This protocol describes an optimized signal amplification strategy to develop an ultra-sensitive magneto-electrochemical biosensing platform. The new protocol combines the advantages of carbon nanotube (CNT) and reduced graphene oxide (rGO) together with electrochemical bursting of magnetic nanoparticles. The method involves synthesis of gold-iron (Au/Fe) nano-structures functionalized with specific antibodies to be used as nanobioprobes (Ab-Au/Fe). The next step requires the precise designing of the rGO/CNT nanohybrid sensing platform. The combined system offers the enhanced electrochemical properties giving a synergistic effect in electroanalytical performance of the resulting electrode material along with a large number of metal ions (Fe2+) available on electrode demonstrating ultra-high sensitivity of developed assay. This method provides a promising biosensing platform for environmental or clinical applications where sensitivity is a major issue

The protocol looks very exciting for sensitive detection of analytes, and could be an alternate for existing techniques
thanks
Very exciting protocol for sensitive detection of analytes. I need more details on the electrode characterization part of this method.
A simple, efficient and innovative approach for biosensing, using new generation smart nanoscale materials (graphene, CNTs and Fe/Au nanocrystals) has been presented. The technique may be useful for development of new highly efficient biosensors. Definitely an impressive piece of work.

very nice protocol:)i really like the stuff.
I think this is a pretty elegant protocol. The whole idea of combining the advantages of both reduced Graphene Oxide and Carbon Nanotube nanohybrid to achieve an enhanced synergistic effect for electroanalytical performance is pretty exciting. Since enhanced sensitivity is a major issue as mentioned, the whole process gives a very elegant way of utilizing the nanometer sized magnetic particles of iron, coated with another inert layer for enhanced biosensing. Regards!
Congratulations to the Authors for this game changing innovation, I encourage you to bring this to the market , it seems to have huge potential for low cost diagnostics
