چکیده

We have demonstrated a microfabricated single-molecule DNA sizing device. This device does not depend on mobility to measure molecule size, is 100 times faster than pulsed-field gel electrophoresis, and has a resolution that improves with increasing DNA length. It also requires a million times less sample than pulsed-field gel electrophoresis and has comparable resolution for large molecules. Here we describe the fabrication and use of the single-molecule DNA sizing device for sizing and sorting DNA restriction digests and ladders spanning 2-200 kbp.

Microfabricated Devices for Sizing DNA and Sorting Cells

We have microfabricated devices to size and sort microscopic biological objects, ranging from cells to single molecules of DNA. Sizing is accomplished by fluorescent excitation and detection. The devices are fabricated in a silicone elastomer using a replica method. Single molecules of DNA have been sized to 10% accuracy, and manipulation of E. Coli cells has been demonstrated.

Sizing and Sorting of Single Dna Molecules by Microfluidic Molecular Combing Device

We report a microfluidic molecular combing device to trap, stretch, and separate DNA at a singlemolecule resolution. In order to align long DNA into a single direction on surface, we demonstrated molecular combing by dewetting DNA solution inside a microfluidic channel. It used a surface tensional force at the air-water interface of DNA solution translating on a fabricated pattern (zigzag line)...

Optimal Placement and Sizing of Distributed Generation Via an Improved Nondominated Sorting Genetic Algorithm II

The use of distributed generation units in distribution networks has attracted the attention of network managers due to its great benefits. In this research, the location and determination of the capacity of distributed generation (DG) units for different purposes has been studied simultaneously. The multi-objective functions in the optimization model are reducing system line losses; reducing v...

Concentrating genomic length DNA in a microfabricated array.

We demonstrate that a microfabricated bump array can concentrate genomic-length DNA molecules efficiently at continuous, high flow velocities, up to 40 μm/s, if the single-molecule DNA globule has a sufficiently large shear modulus. Increase in the shear modulus is accomplished by compacting the DNA molecules to minimal coil size using polyethylene glycol (PEG) derived depletion forces. We map ...
