3D HD-MEA , because planet earth is not flat either

Current flat technologies cannot measure the majority of neurons in a tissue or organoid.
Our first-in-class chip design comes with unique potential:

Measurement supremacy

Reproducible probing of cytoarchitecture,
label-free deep access to biologically relevant cells.

Integrated microfluidics

Increased cell viability,
Flawless compound delivery.

Retain tissue integrity

Easy, non-destructive anchoring,
multiple uses, quick turnover.
