contain a set of hard nanostructures on a surface that can be used as-is for immediate applications or transferred to other materials by replication, such as soft-lithography. Pillars on the silicon master can turn into holes in your assembly template used for nanoparticle deposition.

Soft-lithography is a very powerful and economic technique providing defect-free inverted nanoscale patterns of the master. It allows producing hundreds of polymer replicas. Our masters are coated with an anti-stictioncoating that ensures many replication cycles.

The success of nanoparticle deposition depends on the height and the size of the traps, therefore it is important to match the diameters of the nanoparticles with the linear dimensions of the mold, or vice versa. Typical dimensions of the pillars range from tens to hundreds of nanometers and typical arrangements are a square or triangular lattice with spacings of hundreds of nanometers. We offer areas as large as 4 cm2, other sizes available upon request.
