New microarray chip improves drug safety, helps stop animal testing

Jonathan West a micro-engineer and his colleagues at the University of Dortmund in Germany, has  developed the new microarray chip which can test an estimated 30,000 chemicals  their toxicological risk.

Called a Network Formation Assay (NFA), the chip lets researchers test compounds faster and more reliably. A normal drug test takes up to 10 hours because each compound is tested 30 times at 10 different doses. With this new chip, it will take just a few hours at most.

This approach involves patterning neuronal cells within a hexagonal array to standardize the distance between neighbouring cellular nodes, and thereby standardize the length of the neurite interconnections. This feature coupled with defined assay coordinates provides a streamlined display for rapid and sensitive analysis

The invention includes a new protocol for the detection of the neurite outgrowth, which requires neither fixation nor staining of cells.
