Project Diagnosis of Trimethylaminuria with a Handheld Optoelectronic Nose



The inventors have developed a sensitive handheld device which can detect TMA vapors at concentrations well below the diagnostically significant concentration of TMA. Current methods require expensive instrumentation, complicated preparation of sensors, lack of portability, and long times of analysis.



  • Method of detection not limited to handheld devices (which the manuscript addresses)
  • First report of a line reader/sensor for a biological application
  • Novel method of TMA detection
