Amorphous Carbon Plate

Nippon Light Metal Company, Ltd. has developed a new amorphous carbon plate utilizing their expertise in carbon material production, grinding/polishing technology, and surface modification technology.
We have partnered with Nippon Light Metal Company to sell these amorphous carbon plates in Japan and also worldwide since 2019.

Feature① High Sensitivity

Low Auto-fluorescence Less Non-specific Adsorption of Proteins

Feature② Ease of Use

Amorphous carbon plates are light-weight and very durable.
Functional groups such as amino / carboxyl are covalently bonded to the surface of plate.
Therefore it is hard to remove by washing or chemical reactions.

Feature③ Highly Customizable

The type of functional group, pattern, amount as well as the plate’s shape, size, thickness are all customizable.

  (Example) 1536 spot pattern

The amorphous carbon plate can be customized to various different designs of surface modifications such as a 1536 spot pattern or a full surface modification.
If there is a design you are interested in, please contact us for more details.

Feature④ Recyclable – Low Long-term Cost

The plates are reusable after re-polishing and surface modification, greatly reducing the long-term cost of the plates over time.

Application Example

Serum Autoantibody Detection by Human Protein Array Using Carbon Plate

Experiment Flow

Comparison Study
Assays are performed with commercially available SS-A and SS-B antibody ELISA,
and results were compared to that of amorphous carbon plates.


The results suggest that the detection system built with the amorphous carbon plates performs equally or better than ELISA in terms of sensitivity.
Additionally, the amorphous carbon plate system would allow for the detection of multiple antibodies at the same time, something that other assays cannot achieve.
