WEBINAR: Smart Cell Monitoring & Analysis
Fundamental Challenges in Biomedical ResearchBridging between model systems and true physiology
How relevant are the models that we use? Do they reliably inform us? Are they predictive and ‘translational’?
Recognising added complexity
Genetics, Epi-genetics, Environment Patients are unique and change over time

WEBINAR: Smart Cell Monitoring & Analysis
Continuous Live-Cell Analysis: Electrical✔ Impedance or extracellular field potential (MEA)
✔ In situ (incubator) via specialist electrode plates
✔ Signals are non-invasive, label-free, long-term
✔ Applications - Neuronal, Cardio-myocyte, Other
✔ Surrogate for a number of cellular phenotypes e.g. proliferation, adhesion
✔ Impedance signals can be difficult to interpret. High cell numbers usually required. Consumables are costly.
