In microfluidics, the emergingfield of microphysiological systems (MPS) is overcoming the challenge ofphysiological irrelevancy by animal models for drug discovery and development. Liver function iscritically influenced by drugs owing to its role in drug metabolism and detoxification. Human serumalbumin (HSA) is one of the most important secreted biomarkers which indicate normal liver function. Amicrofluidic albumin immunosensor was developed to be integrated with liver-on-a-chip MPS forcontinuous feedback over disease modeling and treatment. A gold-electrode based electrochemicalimmunosensor was established by anti-HSA antibody immobilization. The liver MPS was found to beefficient for live monitoring of disease modelling and drug treatment over the period of 6 days. Thesystem emulated and analyzed real-time toxicity modeling with HSA sensing. The detection limit ofintegrated sensor was 1 mg/ml with successive reproducibility. The proposed sensor was also validatedwith metabolic biomarkers’ assays. Molecular assays supported the sensor monitoring and depicted liverinjury and recovery. The liver MPS with combined albumin sensor chip may be a promising platform tomimic real-time drug assessment.
