AB  - Electrical-based biosensing platforms offer ease of fabrication and simple 
      sensing solutions. Recently, two-dimensional (2D) semiconductors have been proven 
      to be excellent for the fabrication of field effect transistors (FETs) due to 
      their large transconductance, which can be efficiently used for developing 
      sensitive bioplatforms. We present a 2D molybdenum trioxide (MoO3) FET based 
      biosensing platform, using bovine serum albumin as a model protein. The 
      conduction channel is a nanostructured film made of 2D alpha-MoO3 nanoflakes, with 
      the majority of nanoflake thicknesses being equal to or less than 2.8 nm. The 
      response time is impressively low (less than 10 s), which is due to the high 
      permittivity of the 2D alpha-MoO3 nanoflakes. The system offers a competitive 
      solution for future biosensing applications.
