Nano-TAB Extensions---Since the material file does not exist in the ISA-TAB specification, the entire file is considered an extension.  This file is described in detail in the Appendix.

1.1.1.1 The MATERIAL section allows for the description of the nanomaterial formulation and any materials (including material parts) associated with the nanomaterial formulation.  A formulation is the nanomaterial and any other components or medium.  A formulation can also be any non-biological material sample (for example, small molecule) analyzed in experiment.  The MATERIAL section supports the following types of information:

(1) Material identifier, material name, material type, and material description;

(2) Description of the synthesis and rationale for design;

(3) Chemical name and characteristics of the material; and

(4) Intended application of the material.

1.1.1.1       Description

The Material file describes the composition of the material formulation and is not included in the ISA-TAB specification.  The Material file is an important file that is designed to allow for nanomaterial comparison across nanotechnology resources.  The Material file also allows for the association with an optional Structure file for representing the 3D structure of the nanomaterial.
