Tobacco Mosaic Virus Biotemplated Electrochemical Biosensor Academic Article uri icon

abstract

  • This work demonstrates the first utilization of virus molecules as nano-scale biotemplates assembled on an electrochemical biosensor, allowing for an 8-times increased signal and an improved biosensing performance of 9.5-fold. The versatile and inexpensive biological Tobacco mosaic virus was integrated as a high aspect ratio, low footprint, low-cost, easy to genetically functionalize, nanostructured three-dimensional scaffold for the synthesis of novel multifunctional electrodes. The biotemplated scaffold allows for an increased surface area resulting in higher electrochemical currents, better signal-to-noise ratio and improved sensitivity when incorporated into miniaturized biosensors.
