Caltech Scientists Infuse Arts And Science TO Recreate Van Gogh's ‘Starry Night’ With Glowing DNA Origami [VIDEO]
Scientists at the California Institute of Technology (Caltech) has successfully recreated post-Impressionist artist Vincent Van Gogh's a famous painting The "Starry Night". But what is exciting about this accomplishment is that Caltech scientists did not use any conventional painting methods. Instead they used folded DNA to home fluorescent molecules inside tiny light resonators. This technique is called DNA origami.
Caltech scientists attempt to recreate Van Gogh's "Starry Night" produced a remarkable monochrome image just like Van Gogh's original masterpiece, Tech Times reported.
Meanwhile, DNA origami technique was developed ten years ago by a Caltech alumnus, Paul Rothemund. This technique has allowed experts to fold a long strand of DNA and mold them into different shapes. The folded and shaped DNA will form a scaffold from which scientists will attached and work various kind of components on the nanometer scales from electrically conductive carbon nanotubes and glowing molecules including drugs.
Rothemund, who currently serves as a research professor, compared DNA origami and the folded DNA to the pegboards people are using as tool organizer. He found out that in this case, the pegboard gathers itself from folded DNA strands and the tools find their own stations. All the process happens inside the test tube not demanding aid from human, Rothemund added, Tech Times added.
Rothenmund and his colleagues at IBM Research described a process seven years ago through which DNA origami could be placed at precise locations on surfaces. Since then, Rothenmund and Ashwin Gopinath have polished this technique so that DNA shapes can be exactly placed on almost any surface used in the expansion of computer chips.
Researchers stimulated the PCCs in 20 nanometer steps and charted out a checkerboard pattern of spots from where the molecular lights are either glowing intensely or strongly. The team was able to place glowing molecules to brand lamps of different intensities. Therefore, the work of art was formed.
