Matexcel, a leading service provider in material science, with years of commitment to supplying better material products for worldwide customers from both academia and industry, now presents different surface nanopattering techniques to fabricate nanotemplates in different materials with various feature shape and size.
Micro-/nanoscale topographic surfaces have many outstanding properties and are widely used in biomedical devices, microfluidic devices, and energy device manufacturing. In addition, the clinical application of biomaterials can be greatly expanded with the help of nanostructured surfaces. For example, the current study shows that nanotopologies have the ability to prime specific cues and promote controlled differentiation of stem cells in vitro. Similarly, nanopatterned gold rods are widely used for biosensing studies in biologically relevant systems.
Nano-patterned polymer surfaces have attracted increasing attention due to their potential use as templates and scaffolds for the fabrication of functional nanomaterials. For example, in order to fabricate large area graphene nanonets, patterned negative photoresist layers (polymers) on graphene grown by chemical vapor deposition on copper foils are required as etching masks. An in-depth study of bio-interface interactions has recently been performed on nanoporous polymer surfaces because polymer nanopores provide a protective environment for encapsulated biomolecules. Methods have been developed to construct nanoporous membranes, including patterned surfaces, sol-gel processes, polyelectrolyte multilayers, vapor deposition, and phase separation with selective dissolution.
Now, Matexcel fabricates nanostructured polymer surfaces with diverse shapes and sizes, through different lithography technique. Moreover, Matexcel also provides nanoporous block copolymer thin films, since block copolymers are well-known to self-assemble into nano- and meso-scale structures. Those nanoporous templates are also widely used in the preparation of nanoarrays. Depends on different research needs, Matexcel offers different surface nanopatterning technique to fabricate nanotemplates in different materials with various feature shapes and sizes. The company’s technique includes but not limited to:
Photolithography
At Matexcel, the photolithography process achieves minimum feature sizes down to one to two microns.
Scanning Probe Lithography
Matexcel has applied SPL on a wide range of materials, including metal nitride thin films, SAMs and monomers.
Nanoporous Block Copolymer
Scientists at Matexcel fabricate a variety of nanoporous block copolymer templates which can find promising applications in different research areas.
