In recent years, the field of biomedical research has been dramatically transformed through the advent of three-dimensional (3D) cell culture systems, notably organoids. These miniature organ-like structures hold immense promise for mimicking the complex architectural and functional properties of native organs, surpassing the limitations inherent to traditional two-dimensional (2D) culture systems. With the capability to replicate essential cellular interactions and microenvironments, organoids provide a more physiologically relevant platform for understanding human biology and disease mechanisms. As researchers explore the potential of organoids to revolutionize drug discovery, disease modeling, and personalized medicine, there is a pressing need for sophisticated analytical techniques to assess their multifaceted characteristics accurately.

The identification and application of compatible analytical platforms are pivotal to the successful characterization of organoids. Traditional methods often fail to capture the intricate electrophysiological, biophysical, and optical properties inherent in these 3D structures. As such, researchers are increasingly turning to advanced technologies that allow for a more comprehensive understanding of organoid function, behavior, and development. By integrating omics approaches and computational modeling with experimental data, scientists can forge a pathway to elucidate the biological principles governing organoid physiology. This multidisciplinary approach promises to enhance the reliability and applicability of organoids in clinical and industrial settings.

Electrophysiological assessment is one crucial aspect that cannot be overlooked. The ability to monitor cellular electrophysiology within organoids reveals invaluable insights into neural function, cardiac rhythms, and tissue connectivity. Techniques such as extracellular recordings and patch-clamp electrophysiology are becoming standard in organoid research, enabling scientists to analyze the functional behaviors of electrically active cells. By understanding how electrical signals propagate through organoid structures, researchers can gain a deeper understanding of various pathophysiological conditions, including neurological disorders and arrhythmias.
