DNA stretched on silicon chip
WEST LAFAYETTE, Ind. (UPI) -- Purdue University researchers say they're a step closer to using DNA in computers and other future electronic devices. The researchers have stretched a piece of DNA on a silicon chip so that it can be read easily.
In a paper written for the journal Advanced Materials, Assistant Professor Albena Ivanisevic and grad student Dorjderem Nyamjav described creating templates containing charged lines of commercially available polymer, New Scientist reported.
They then added negatively charged DNA to the positively charged polymer and used a syringe to drag the strands along the chip's surface.
"The charged structures enable us to direct biological molecules in a certain location," Ivanisevic told New Scientist. Ivanisevic's research is the first to show how to stretch the DNA strands in specific locations. The technique also can be used with other biological molecules like proteins and viruses.
