OmniCellar is a high-precision platform that combines 3D bioprinted organ-on-a-chip models with aptamer-based electrochemical sensors to monitor tissue health in real time. These sensors track glucose and lactic acid levels every 30 minutes for up to a week, revealing disease progression and drug effects with exceptional accuracy. By replacing destructive lab testing with dynamic metabolic readouts, OmniCellar helps researchers predict treatment outcomes more reliably, reducing development costs and accelerating therapies for chronic and age-related diseases
