caption[0] = "A simple, fast all-plasma surface modification technology has been developed by NanoFab staff to form super-hydrophobic and/or super-hydrophilic surfaces over large areas. The wetting property can be switched between super-hydrophobic and super-hydrophilic by simply changing the plasma chemistry. Both super-hydrophobic and hydrophilic areas have been created on a single surface by using a stencil mask to selectively modify areas on the surface with different gases.

caption[1] = "The CNST NanoFab is now offering its users a silicon nitride membrane process. Membranes can be used as starting &quot;platforms&quot; for the fabrication of a multiplicity of micro-and nanoscale devices. Membranes 100 nm thick can be fabricated in sizes ranging from 1 mm x1 mm to 5 mm x 5 mm, suspended over a silicon frame that is typically 1 cm x 1 cm. The silicon nitride is grown by LPCVD, and is under a tensile stress of 150-250 MPa.

Light interacts with nanostructured matter to produce novel nanoscale phenomena, enabling the fabrication of an Integrated Nanoplasmonic Measurement Structure with the following functionality: 1) On-chip optical communications to break speed bottleneck; 2) Optical sensing at the nanoscale for chemical or biomolecule detection at physiologically relevant concentrations; 3) Intense fields for nanoparticle manipulation<br>(<i>Research by H.
