To fully automate the readout of genotypes, the current efforts focused on optimizing the computational software to work in conjunction with the system's optics to evaluate the intensity of the hybridization spots on the DNA array and to report the genotypes at multiple loci.
Seeman says that the creation of this device enhances his earlier work-a single nanorobotic arm he completed in 2006, marking the first time any scientist had been able to employ a functional nanotechnology device within a DNA array.
When a protein from the sample under test sticks to the biochip DNA array, the attachment distorts the underlying polymer molecules, changing their optical properties and making them fluoresce.
The resulting Southern blot is considered to be the first DNA array (Southern 2000).
The assay combines the specificity obtained by enzymatically labeling DNA probes with the potential for detecting several targets simultaneously by using DNA array hybridization.
