Asahi Kasei, a Japanese chemical company, has developed NanoAct cellulose nanobeads as labels for lateral flow immunoassay and other assay applications.

Immunoassay is a method that generally utilizes an antigen-antibody reaction. It gives a positive or negative result by simple visual observation of the presence or absence of a coloured line, without the need for any special equipment.

Compared to conventional labels, NanoAct features higher sensitivity, faster detection time, and availability in multiple colours to allow easy multiplexing. The properties of cellulose such as excellent colourability and hydrophilicity make NanoAct ideal for use as labels in immunochromatography, Asahi Kasei said in a statement.

While conventional labels experience drawbacks such as difficulty of detecting antigens at low concentration, slow detection time, and lack of colourability, NanoAct provides superior performance to successfully overcome each of these drawbacks. In recognition of these advantages, NanoAct has been adopted as the label for an influenza A and B assay in Japan.

Asahi Kasei fibres has begun commercial production and supply of NanoAct cellulose nanobeads, and is now accelerating the development of lateral flow immunoassays in Japan and worldwide.

The Asahi Kasei Group is organized in a holding company configuration with eight core operating companies in four business sectors that include chemicals & fibres. (GK)
