investigators at MIT have invented a temporary "tattoo" made from genetically programmed living cells. It's divided into sections printed by a slurry containing live pathogenic bacteria which fluoresce while they come into contact by particular compounds. study & Growth into stimuli-responsive materials which could be developed into Intelligent materials has been going on for decades. however a team of engineers led by MIT professor Xuanhe Zhao realised which there perhaps be a method to Utilize living cells - easy obtained & easy programmable - in a 3-dimensional-printed reactive material. The team printed the Analysis pattern onto elastomer, then stuck it to skin which had been smeared by chemicals.
scholars innovate World's Smallest Mona Lisa Utilizing DNA; It Is The Same Size As pathogenic bacteria
scholars have created the world's smallest copy of Italian polymath Leonardo da Vinci's famous painting 'Mona Lisa' Utilizing DNA. A single-stranded DNA molecule is composed of smaller molecules called nucleotides - abbreviated A, T, C, & G - arranged in a string, or sequence. A Big DNA canvas is assembled through many smaller square origami tiles, like putting together a puzzle. investigators developed software which could take an image like the Mona Lisa, divide it up into small square sections, & set the DNA sequences needed to make up those squares. "The protocol could be directly read with a liquid-treating robot to automatically mix the DNA strands together.
scholar innovate The World's Smallest 'Mona Lisa' Utilizing DNA–It's The Same Size As pathogenic bacteria
referring to According to The Daily Mail, the mini Mona Lisa measures 0.five square micrometers that is approximately the same size as E-Coli pathogenic bacteria. while the short staples & the long strand are meshed together in the laboratory, the staples clump areas of the long strand together. The world's smallest Mona Lisa is too the world's largest DNA origami structure. pic.twitter.com/udgDWTq1Lo — Caltech (@Caltech) December six, 2017As Engadget reports, it's a combination of the capabilities of software & liquid manipulation in the laboratory. The investigators too "drew" portraits of pathogenic bacteria & a rooster to illustrate what they were enable to of doing by DNA origami.
