Home » Frequently Asked Questions About In Vitro Irritation and Cytotoxicity Testing
Biocompatibility assessments are a battery of tests performed to evaluate a product, medical device, or other material for the risk of biological hazards. The first test performed is typically a cytotoxicity evaluation. This is done by preparing an extract of the sample to treat a monolayer of healthy mammalian cells in vitro. Results of this assay can indicate the potential toxicity risk a product carries without testing on animals.
Irritation is a localized non-specific inflammatory response to a single, repeated, or continuous application of a substance or material. The in vitro irritation test involves an extraction in physiologically relevant solvents. These extracts are applied to a reconstructed human epidermis model which contains the major layers of cells that are found in a true human epidermis. Death of the cells in this model after exposure to the extracts collected from a product indicate that an irritating substance was leached off the material and poses a risk of adverse reactions in the end user.

FIB Circuit Edit provides the ability to quickly perform nano-surgury by cutting traces or adding metal connections at the chip level
FTIR, Raman and NanoIR are particularly well suited at determining the identity and molecular structure of organic materials, however they can also obtain some inorganic information too.
APT is a nanoscale materials analysis technique that provides 3D spatial imaging and chemical composition measurements with high sensitivity simultaneously.
