Scope

This standard (ISA-TAB-Nano) specifies the format for representing and sharing information about nanomaterials, small molecules and biological specimens along with their assay characterization data (including metadata, and summary data) using spreadsheet or TAB-delimited files.

Prerequisites

Familiarity with the fields of nanotechnology and nanomedicine is a prerequisite for this specification. An understanding of ISA-TAB is recommended but not required as the ISA-TAB-Nano specification provides descriptive information on ISA-TAB as applied to nanotechnology.

Version

The current version of ISA-TAB-Nano is Version 1.2 (March 2014). Differences between Version 1.2 and 1.1 are described in the ISA-TAB-Nano 1.2 Release Notes. Differences between Version 1.1 and 1.0 are described in the ISA-TAB-Nano Code Fest De-Brief presentation and in the ISA-TAB-Nano 1.1 Release Notes.

The ISA-TAB-Nano project is an effort of the National Cancer Institute (NCI) National Cancer Informatics Program (NCIP) Nanotechnology Informatics Working Group (Nano WG).

ISA-TAB-Nano Standards Re-Use

...

Like ISA-TAB, ISA-TAB-Nano provides fields for entering and referencing terms selected from ontologies and standard terminologies. The ontologies are available at BioPortal (http://www.bioontology.org)

, which is maintained by the National Center for Biomedical Ontologies. Though the investigator may use alternative ontology and vocabulary sources, the ability to evaluate and share data require that all parties have access to those being used (they should be available to the investigators). All terms and fields used in this standard utilize the NCI EVS (http://evs.nci.nih.gov) and NanoParticle Ontology elements. and NanoParticle Ontology elements.

is an ontology that is designed and developed within the framework of the Basic Formal Ontology (BFO) and implemented in the ontology web language (OWL). It is being developed to represent the knowledge underlying the description, preparation, and characterization of nanomaterials. NPO development began with the representation of knowledge underlying the chemical composition, preparation, physiochemical, and functional/biological characterization of nanoparticles that are formulated and tested for applications in cancer diagnostics and therapeutics. The NPO provided the knowledge framework for developing the ISA-TAB-Nano material file format. The NPO provides a subset of the terms and relationships for the description and characterization of nanomaterials in the ISA-TAB-Nano file format. The NPO is being further developed for the following purposes: (1) to provide terms for annotating nanotechnology research data; (2) to provide the knowledge framework required for developing data-sharing models and standards in nanomedicine; (3) to enable semantic integration of data; (4) to enable unambiguous interpretation of the description and characterization of nanomaterials; and (5) to enable knowledge-based searching and comparison of nanomaterial descriptions and characterization results.

Investigation Title: Nanotechnology Characterization Laboratory (NCL) Dendrimer-Based MRI Contrast Agent

Investigation Description: The objective of this investigation is to characterize a PAMAM dendrimer with an associated gadolinium chelate MRI contrast agent. The nanomaterials submitted for testing at the NCL were (NCL20) G4 tris (hydroxyl) terminated PAMAM dendrimer, (NCL21) G4 pyrrolidinone terminated PAMAM dendrimer, (NCL22) G4.5 COONa terminated PAMAM dendrimer, (NCL23) G4.5 COONa terminated PAMAM dendrimer-Magnevist® complex, (NCL25) G4 tris (hydroxyl) terminated PAMAM dendrimer-Magnevist® complex, and (NCL26) G4 pyrrolidinone terminated PAMAM dendrimer-Magnevist® complex. Commercially available Magnevist® (NCL24) was used as a control. NCL studies addressed in this report can be divided into three main categories: physicochemical characterization; immunotoxicology; in vitro toxicology.
