Nanotechnologies — Nano-object-assembled layers for electrochemical bio-sensing applications — Specification of characteristics and measurement methods

This document 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. It 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; — the packaging, labelling, expiratory dates and transport of nano-object-enhanced electrochemical electrodes.
