Biocompatibility of 2D silicon nitride: interaction at the nano-bio interface

Chemistry at the nano-bio interface.

The interface of biology and inorganic materials represents one of the fastest growing and most promising areas of nanotechnology. The fifth issue of JACS Select contains 22 Communications and Articles from 2008 and early 2009 that illustrate the breadth and creative energy of this young field. Although the use of colloidal particles of metals and semiconductors as pigments dates back many cent...

Probing the Interaction at the Nano–Bio Interface Using Raman Spectroscopy: ZnO Nanoparticles and Adenosine Triphosphate Biomolecules

With the advent of nanobiotechnology, there will be an increase in the interaction between engineered nanomaterials and biomolecules. Nanoconjugates with cells, organelles, and intracellular structures containing DNA, RNA, and proteins establish sequences of nano-bio boundaries that depend on several intricate complex biophysicochemical reactions. Given the complexity of these interactions, and...

In this proposal we seek to establish a porous silicon based etching process in the WTC microfabrication laboratory. The new process will allow us to etch high aspect ratio holes through a wafer. Holes like these are important for decreasing the dead volume of connections between micro and macro systems and for increasing the complexity of micro-fluidic systems. At the present time, the minimum...

Fabrication of 2D silicon nano-mold based on sidewall transfer

A method based on the sidewall transfer technique for fabricating two-dimensional (2D) nano-mold on a silicon substrate was developed. Instead of using expensive nanolithography, the authors fabricated 2D silicon nano-mold using standard ultraviolet lithography, conformal deposition of gold by radio frequency sputtering, argon sputter etching and deep reactive ion etching (DRIE). This technique...
