Automated MicroContact Printing, Uniform Micro and NanoPatterning

Innostamp.png Soft lithography is one of the main parts of the BIOSOFT toolbox and more specially the   microcontact printing. For that, BIOSOFT has a fully automated microcontact printer named InnoStamp40.

Combining microcontact printing flexibility and high-precision automation, the InnoStamp 40 is perfect for nano and micropatterning. A user-friendly system, the InnoStamp 40 allows users to control their processing in order to transfer a wide range of components homogeneously onto defined surfaces.

As a new fully automated microcontact printing solution, the InnoStamp 40 offers high-precision and uniform contact for sub-micron resolution.

 Automation by Magnetic force

The InnoStamp 40 is a microcontact printing device based on magnetic technology . The magnetic field is used in two manners:

  • First of all, a magnetic head handles a magnetic stamp by loading and unloading it throughout the entire microcontact printing process (loading, inking, drying, alignment, printing, cleaning, unloading).
  • Secondly, strong magnets at the bottom of printing area apply a precise and homogeneous pressure on the magnetic stamp during the printing step in order to transfer nanoobjects onto the surface according to its specific patterns.

InnoStamp40 and InnoScan1100 : a complete plateform to fabricate and read fluorescent patterns

The complete platform for NanoBiotechnology applications is composed of InnoStamp40 and InnoScan1100. It combines a fully automated microcontact printer and a fluorescence scanner.
