Researchers have developed a quick method for extraction of single DNA molecules for positioning them in nanoscale slits. This method is being termed as efficient and inexpensive. It is expected to lead to faster sequencing technology and one day may even lead to underpinning the ability of clinicians for obtaining customized DNA profiles of patients. Using nanotechnology a mold was fabricated for developing a rubber template with slits for confining single strands of elongated DNA. This has given the scientists a convenient way for manufacturing large number of individual DNA molecules for study purpose. This helps in getting a number of molecules for analysis and sequencing and hence become more accessible to science. Schwarts stated: To get DNA molecules to do this on surfaces is really hard. The system developed by Schwartz, de Pablo and their colleagues could change all of that. By figuring out a way to take individual DNA molecules and present them in a confined, linear fashion, the genetic information encoded in the arrangement of the base pairs that make up the molecule can be scanned and read like a bar code.
