  1. Significance With sequencing, it is possible to: identify genes for genetic disorders such as cancer or cystic fibrosis, identify suspects in crimes, differentiate different pathogens and be used in the field of genetic engineering. However, DNA sequencing is both expensive and time consuming. The hydraphile is a potential nanopore for sequencing which can reduce the cost and time. Hydraphile Nanopore as the Future in DNA SequencingSaifuddin Aijaz1, Aaron Choi2, Davis Sneider3 Faculty Mentor: David Wendell,PhD1 1Department of Biomedical, Chemical, and Environmental Engineering, University of Cincinnati, Cincinnati, OH2Department of Electrical Engineering and Computing Systems, University of Cincinnati, Cincinnati, OH3Department of Electrical and Computer Science, George Washington University, Washington, D.C. Goals • Test ability of nanopore under different buffer conditions • Used nanopore to pass DNA Results Conclusions Passed DNA through nanopore: Hydraphile nanopore was found to translocate all lengths of DNA. These lengths were found to produce blockage events across the nanopore. The fragments were found to have unique blockage pattern. Found approximate dwell times: Dwell time per base pairs were found to be similar to alpha hemolysin. Dwell time was found to decrease with increasing fragment length. The hydraphile could be used to sequence DNA: Conductance characteristics of the nanopore were found to fall in the range of other nanopores used for DNA passage. The high average dwell time per base pair indicates that this nanopore could be used for DNA sequencing. Methods Acknowledgement The hydraphile was inserted into vesicles made of DPHPC and fused into a bilayer lipid membrane. Conductance of the nanopore was measured by electric current recordings for DNA fragments of lengths 250 bp, 500 bp, 1000 bp, 2500bp, and 5000 bp.
