MaxWell Biosystems MaxOne+ HD-MEA Chip

Building on the reputation of MaxWell Biosystems’ high-density microelectrode arrays (HD-MEAs), the company’s next-generation electrode design is designed to advance the current technology even further. The MaxOne⁺ HD-MEA Chip provides an upgraded performance and user experience through its optimised surface for cell adhesion, high signal quality, enhanced electrical stimulation efficacy and ease of use — making it suitable for applications such as organ-on-a-chip research, brain slice/organoid studies, retinal studies and single-cell level analysis.

The product enables users to cultivate healthy cells and tissue on a soft and biocompatible surface. All 26,400 electrodes are coated with PEDOT, offering a sponge-like structure that promotes good cell adhesion, viability and stability — suitable for longitudinal experiments.

The device is designed to evoke electrical responses from cells with efficacy and precision. By leveraging high-density electrodes, an advanced electrode-tissue interface and optimised material properties, the product offers enhanced cell and network stimulation.

Users can capture cell activity with high fidelity, with 1020 recording channels. With reduced background noise, the device features good HD-MEA signal quality, achieving a 50% increase in sensitivity over the previous model. Experimental time and consistency is meanwhile optimised via ready-to-use chips treated with standard sterilisation processes and featuring automatic Chip ID recognition.
