Labcyte’s Echo devices create and eject these objects using acoustic energy. The McCarroll lab developed a protocol named for these objects that makes beads called STAMPs (“stamps”) that are coated in RNA. These objects are made by vortexing Span-80, Tween-80, and sodium deoxycholate (-5[1])(“dee-oxy-KO-late”) in a technique for high-throughput enzyme evolution called IVC. Reagents are added to these objects by picoinjectors. Flow focusing generates these objects by mixing (-5[1])two streams at a T- (10[1])or Y-shaped (-5[1])junction on a chip. Digital (-5[1])PCR generates trillions (10[1])of these objects, (10[1]-5[1])each of which contains zero or one copy of DNA. (10[1])These objects act as mini-reactors in a common format (10[1])for microfluidics, where they are formed (-5[1])by emulsifying picoliters of water in oil. A Taylor cone (10[1])disperses (-5[1])bioanalytes into these objects during electrospray (10[1])ionization.
