Design Flow Enhancements for DNA Arrays

چکیده
DNA probe arrays have recently emerged as one of the core genomic technologies. Exploiting analogies between manufacturing processes for DNA arrays and for VLSI chips, we demonstrate the potential for transfer of methodologies from the 40-year old field of electronic design automation to the newer DNA array design field. Our main contributions in this paper are the following. (1) We give a new design flow for DNA arrays which enhances current methodologies by adding flow-awareness to each optimization step and introducing feedback loops. (2) We propose solution methods for new formulations integrating multiple design steps, including probe selection, placement, and embedding. (3) We give results of a comprehensive experimental study showing that significant improvements in solution quality can be achieved by using the enhanced methodologies.

متن کاملA robotics platform for automated batch fabrication of high density, microfluidics-based DNA microarrays, with applications to single cell, multiplex assays of secreted proteins.
Microfluidics flow-patterning has been utilized for the construction of chip-scale miniaturized DNA and protein barcode arrays. Such arrays have been used for specific clinical and fundamental investigations in which many proteins are assayed from single cells or other small sample sizes. However, flow-patterned arrays are hand-prepared, and so are impractical for broad applications. We describ...
متن کاملOptimization of Array Factor in Linear Arrays Using Modified Genetic Algorithm
The array factor (sidelobe level, SLL) of a linear array is optimized using modified continuous genetic algorithms in this work. The amplitudes and phases of the currents as well as the separation of the antennas are all taken as variables to be controlled. The results of the design using modified GA versions are compared with other methods. Two design problems were studied using several contin...
