NanoInk has declared that it will release a force sensor and leveling equipment at the Nanotech Conference and Expo.
The company will also present an oral paper on the advanced dip pen nanolithography (DPN). Force sensing combined with 1D leveling has been incorporated on the NanoArrayer 3000, which was released last week by the company’s Nano BioDiscovery division. This optional feature is also present on NanoInk's NLP 2000.
Molecular biomaterial deposition
When force sensing is combined with automation software, it assists surface plane correction and automated pen array leveling. It can be used for printing nano and micro arrays features across a glass microscope slide uniformly. 2D leveling involves the use of a patented sapphire ball technology that allows large-sized 2D arrays of high-density pens to be spread uniformly on the substrate without any contact, thus eliminating any cross contamination.
NanoInk's NLP 2000 System enables researchers to design and build functionalized and custom engineered surfaces on the nano and micro scale level. This system utilizes a tip-based lithography method, called DPN, to transfer small quantities of materials over a wide and environmentally-controlled work area.
DPN functions under ambient conditions and allows the deposition of a wide range of inorganic, organic, and biological molecules. It is possible to produce features as small as 50 nm and as large as 10 µm using DPN platforms. The company offers proprietary software and micro-fabricated DPN equipment to make the process of depositing several materials simultaneously, thus allowing researchers to pattern micro-and nanoscale features quickly.
