title: Monitoring system of cell's viability and function for bioartificial liver support system.
abstract: OBJECTIVE
  To develop an online cell monitoring system for rapid understanding the cell's viability and functional activity, hence appropriate measures could be adopted in time.
  
  
  METHODS
  Traditional off line technique was changed into online monitoring in this instrument for rapid detecting albumin and urea. Monocolor light source and integrated photoelectric sensor were adopted in this system.
  
  
  RESULTS
  It was demonstrated in experiment that this system was designed of a novel and simple construction, which could fulfill the requirements of measuring the cell's functional activity in Bioartificial liver.
  
  
  CONCLUSIONS
  This design is proved feasible and reliable. It provides a novel system to monitor cell's viability and function on line quickly. Using this monitoring system, the closed-loop controlling of Bioartificial liver support system can be realized.
