Limitations that hinder the broad use of omics technologies in nanotoxicology

Independent from the technology	Technology linked
Lack of standardization of particle exposure	Request for high sample quality (freezing, protection against degradation)
Sample pre-treatment	Expertise in bioinformatics needed for data analysis
Cell type used for testing	Lack of standardization of sample preparation
Medium composition	Predictive value of the omics techniques not entirely clear
Relevant concentration range
