What are Droplet Microarrays (DMAs)?

  • DMAs are transparent and fully planar arrays consisting of hydrophilic spots separated by superhydrophobic barriers based on Aquarray's patented technology
  • Micropatterning enables Droplet Microarrays in the nanoliter range with high-density
  • Use of nanoliter spots enables significant savings

DMAs - A Miniaturized Array Platform

Miniaturization of Microplate Assays

Advantages of Droplet Microarrays

  • Reduces reagent costs by factor of 1000 (less reagent required)
  • Reduces cell costs by a factor of 100 (less cells required)
  • Enables screening of rare patient material or limited biological samples
  • Compatible with adherent and suspension cells
  • Individual ready-to-use drug libraries allow immediate cell screening
  • Applications beyond the microplate can be realized (e.g., MALDI-TOF, on-chip synthesis)
  • Flexible format options, customizable/functionalized surfaces
  • Fast filling of DMAs due to small volumes

DMA Product Range

  • Wide range of DMA slides, DMA plates and accessories for all possible screening scenarios and applications
  • Standard borosilicate glass or ITO-coated glass with conductive and IR-reflective properties
  • Different surface coatings compatible with aqueous media or with aqueous solutions of organic solvents
  • Round or square spots in various sizes, spacings and spot numbers
