ISO Publishes Standard on Characterization and Measurement of Nano-Object-Assembled Layers for Electrochemical Bio-Sensing Applications

Lynn L. Bergeson Carla N. Hutton

The International Organization for Standardization (ISO) has published standard ISO/TS 21412:2020, “Nanotechnologies — Nano-object-assembled layers for electrochemical bio-sensing applications — Specification of characteristics and measurement methods.”  The standard specifies the characteristics to be measured of nano-object-assembled layers on electrodes by means of a solution process and of nano-objects constituting the layers for electrochemical applications such as nano-biosensor or diagnosis applications.  It also provides measurement methods for determining the characteristics.  ISO notes that the standard does not apply to:

  • The requirements of nanostructures by top-down nanomanufacturing;
  • The subsequent coating of materials such as biomaterials onto nano-object-assembled layers;
  • Specific health and safety requirements during manufacturing;
  • The experimental conditions of electrochemical sensing; and
  • The packaging, labeling, expiration dates, and transport of nano-object-enhanced electrochemical electrodes.
