A decade after the idea became the topic of his doctoral dissertation, a researcher at the California Institute of Technology has showed that it is possible to coax short strands of artificial DNA to spontaneously assemble into a Sierpinski triangle.
The DNA Sierpinski triangles show that there is no theoretical barrier to using molecular self-assembly to carry out any kind of computing and nanoscale fabrication, according to (Erik Winfree, an assistant professor of computer science at The California Institute of Technology). If someone comes up with the right rules, the right set of molecules should be able to carry out the instructions, he said.
