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

Material

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:

...

(3) Chemical name and characteristics of the material

(4) Intended application of the material

An Example Material File is shown in TABLE 2.

Material source identifier--- The unique identification name of the source from which the material sample is derived. Its value is used as the value for source name in nano-TAB study files, thereby linking the nano-TAB material file and the study file. For example, NCL-23 (see TABLE 2) is the name that identifies a material characterized by the Nanotechnology Characterization Laboratory (NCL).  This example indicates that the sample NCL-23 is a complex formed out of NCL-22 (a G4.5 PAMAM dendrimer terminated with carboxyl groups) and NCL-24 (magnevist).

The MATERIAL RELATIONSHIP section is used to record the name and types of relationships between materials including material parts and material linkages.  Material parts represent the components within a material.  Material linkages represent association between materials (e.g. encapsulation, attachment, entrapment). TABLE 3 illustrates an example of the MATERIAL RELATIONSHIP section. The concepts used for describing the relationship are given below.

The material file section allows for the association of any files (e.g. image files) to the nano-TAB material file. TABLE 4 illustrates an example of the MATERIAL FILE section.
