SUMMARY:The Physics of 'Centipede' Microdroplet Generation
DESCRIPTION:Lecturer:Dr. Michael Chemama\n Faculty:School of Engineering an
 d Applied Sciences\, Harvard University\,\n Institute:USA\n Location:Class
 room 165\, ground floor\, Library\, Aerospace Eng.\n Zoom: \n Abstract: \n
  Details: \n We explore the physics behind high-throughput devices for the
  production of monodisperse microdroplets. Microdroplets are used more and
  more in a wide variety of applications: to conduct chemical reactions in 
 picoliter volumes\, as biological screening assays or as templates to prod
 uce calibrated microparticles and microcapsules of active ingredients. The
  accuracy of the screening assays as well as the degree of control over th
 e chemical reactions and the release kinetics of active ingredients critic
 ally depend on a very narrow size distribution for the microdroplets. In a
 ddition\, a very large number of drops is required. Unfortunately\, tradit
 ional high throughput methods offer limited control over the drop size.\nI
 n 2013\, the Weitz laboratory at Harvard University introduced a robust de
 vice that produces monodisperse drops at a high throughput. This device\, 
 called centipede because of its hundreds of parallel channels\, allows the
  use of microdroplets for a much broader range of applications. A single d
 evice takes up a volume of 100 mm3 and can produce up to 150mL/h of monodi
 sperse microdroplets: size variations remain below 3%. In this talk we exp
 lain the mechanism through which it produces droplets in order to understa
 nd how the droplets' size is related to the device’s design parameters a
 nd what the limiting throughput is.
