Biochips represent the most advanced method to analyze biomolecules, particularly nucleic acids.
They are arranged in a grid system and spotted onto to the chip surface by nanoprinting. This special biomolecule matrix constitutes the DNA array, the sensitive core of the biochip. An extreme miniaturization enables a high degree of parallelization which permits running series of different analyses simultaneously. When this biochip is available, regulators will have a quicker, cheaper and more reliable way to detect the presence of genetically modified food. LAST autumn, Friends of the Earth, an environmentalist group, sent an assortment of foods to the testing laboratories of Genetic-ID, a biotechnology company based in Iowa.
