Ultra high precision micromachining capabilities and the unique physical properties of single crystal silicon have been combined to create a microcontact printing pin that delivers the highest quality printed spots at the lowest cost available. Even though the microcontact printing of microarrays of many types of biological samples is now and will remain a mainstay of microcontact printing, recent additional applications have emerged in the delivery of whole cells, inorganic materials, hot melt adhesives and solder. On these pages, you can learn about silicon micromachining and how pins made by this technique will allow practitioners of microcontact printing to perform more accurate experiments, at a faster rate and at a lower cost.

Features, Advantages and Benefits of Silicon Microarray™ Technology

  • All pins are precisely identical for the highest reproducibility in printing
  • Low cost
  • Greatly reduced carryover
  • Essentially no prespotting
  • Highly precise volumetric uptake
  • The pins print to dryness utilizing the entire sample taken up
  • No tip bending, blunting or mushrooming
  • Microarray pins with tip sizes from 50µm - 200µm available
  • Uptake volumes of 25-250 nL per dip
  • Print volumes of less than 250 pL per spot
  • Ability to print from 96, 384 and 1536 source plates
  • Ability to chemically modify the pin surface
  • Super elasticity of silicon provides 100% recovery from stresses below the breakage point
  • Non-flat tip texturing provides highly uniform printed spot
