Fig. 1From: Eye irritation testing of nanomaterials using the EpiOcular™ eye irritation test and the bovine corneal opacity and permeability assayMean relative tissue viability of two EpiOcular™ tissues plus inter-tissue difference obtained in the EpiOcular™-EIT. Blue bars represent results obtained applying the protocol for solids ‘variant 1’ (90 min exposure; 12 min post-exposure), green bars - protocol for solids ‘variant 2’ (6 h exposure; 25 min post-exposure) and red bars - protocol for liquids (30 min exposure; 12 min post-exposure)Back to article page
