AI Summary
The Department of Energy's Lawrence Livermore National Laboratory (LLNL) is seeking industry partners to collaborate on the commercialization of its innovative method for fabricating silicon carbide nanoneedles. This technology enables the creation of sharper and thinner nanoneedles, with potential applications in electronics and drug delivery. Interested companies should submit a statement of interest detailing their expertise and facilities. For more information, visit LLNL's Innovation and Partnerships Office website.
Opportunity: Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to enter into a collaboration to further develop and commercialize its Method of Fabricating Silicon Carbide Nanoneedles. Background: Silicon carbide has properties that make it ideal for electronic, MEMS and transdermal drug delivery devices (e.g., high thermal conductivity, chemical resistance and biocompatibility). Conventional fabrication of silicon carbide microneedles uses molds typically prepared by using a mixture of resin and hydrate material. This methods limits the shape of the tapered sharp tip. By adapting semiconductor processing methods to this application may allow for nano-level precision. The challenge is that etching processes, particularly isotropic etching, that work well for silicon do not work for silicon carbide since the latter is relatively inert. Description: LLNL researchers have developed an approach to form silicon carbide (and diamond) nanoneedles using plasma etching that create micro pillars followed by chemical etching of the pillars in forming gas containing hydrogen and nitrogen. Combining these two etching processes allow for fabrication of micro- and nanoneedles that are thinner and sharper than conventionally fabricated needles. Advantages/Benefits: Fabrication of micro and nanoneedles with tips as narrow as 15 nm that cannot be fabricated using conventional fabrication methods (e.g., from molds made of resin and hydrate material). Potential Applications: Optical switches Field emission tips Probes for atomic force microscopes Transdermal delivery of drugs and proteins Electronic applications Diamond nanoneedles Development Status: Current stage of technology development: TRL ? 0-2 ? 3-5 ? 5-9 LLNL has filed for patent protection on this invention.
