Overview

The perfect tool for your brain research

Investigating cellular networks requires time, expertise and effort to obtain the performance necessary to validate research hypotheses. With 3Brain as your technology partner, you can easily capture every cell signal in high resolution.

Our powerful CMOS MEA (microelectrode array / multielectrode array) system collects high-density electrophysiological data from preparations made of brain slices, neuronal tissue, human-derived stem cells,brain organoids, retinal tissue and cardiac cultures and tissues.

Different HD-MEA chip models for our microelectrode arrays are available to match your experimental needs in terms of resolution, field of view and stimulation capabilities.

Electrodes are coated with platinum to provide a stable and fully biocompatible surface. The quality of the recording is ensured by the outstanding signal-to-noise ratio, as you can see from our video samples gallery.

3Brain's HD-MEA technology

Recording and stimulating capabilities for all your applications

Accura HD-MEA

The Accura microelectrode array features 4,096 recording electrodes arranged in a 3.8 mm x 3.8 mm area, a perfect compromise for both cultures and brain tissues. Compared to previous chipset families, Accura achieves an improved signal-to-noise ratio by offering a recording mode where a subset electrode area can be accessed for ultra-low noise performance.

Moreover, every single recording electrode can also be used to release an electrical signal to your sample. The Accura HD-MEA provides a 3.8 mm x 3.8 mm grid of 4,096 electrodes for spatially accurate electrical stimulation at a cellular resolution.

Each microelectrode is 21 µm x 21 µm, with a 60 µm pitch. The internal diameter of the reservoir is 25 mm, with a height of 7 mm.

The Accura HD-MEA is based on the Khíron (Gen 3) chipset family and is compatible with BioCAM DupleX only.

Pre-coated Accura series

Thanks to the AziGrip4™ CELL+ surface functionalization technology developed incollaboration with SuSoS AG, Accura microelectrode arrays can be provided in a pre-coated, sterile and ready-to-use version for cell cultures. By removing the need for manual functional coating and sterilization, both preparation time and variability in cell cultures between MEAs are reduced. Furthermore, it provides a homogeneous and reliable adhesion of cells to substrate, thus increasing the success rate of your experiments.
