Neuroblastoma is the most common solid turnour of childhood with an incidence of about 1 :10,000 births. Prognosis depends on age and stage at presentation and for disseminated disease presenting after the age of 1 year has scarcely altered at all in the past 20 years. In Japan a method has been pio

โฆ Synopsis
Abstract
The feasibility of using nanofabricated arrays as electrophoretic chambers for DNA sequencing is investigated. A specific array design, consisting of rows of closely spaced posts, separated by longer open spaces, is proposed. Molecules driven through the array by an electric field get hooked over obstacles at successive rows and their progress through the device is delayed as a consequence. The dependence of the delay time on molecular size is derived. Numerical evaluation indicates that a device of modest dimensions, operating at high fields, can rapidly resolve oligonucleotides containing several hundred bases.
