Photolithography and DNA tethers used to print cellular messaging environments

Scientists from University of California, Berkeley (CA, USA) have utilized photolithography and DNA tethers to print 2D arrays of cells and proteins, which mimic a range of cellular messaging environments. A team from University of California, Berkeley (UC Berkeley, CA, USA) has developed a novel printing technique which utilizes a DNA tether to attach cells and proteins to a substrate. Paired with this, they used photolithography, a patterning process which uses light, to attach a large number of cells and proteins at once. This novel technique, detailed in Science Advances, has the potential to give us insight into complex cell-to-cell...
