摘要:
A method of etching silicon-and-carbon-containing material is described and includes a SiConi™ etch in combination with a flow of reactive oxygen. The reactive oxygen may be introduced before the SiConi™ etch reducing the carbon content in the near surface region and allowing the SiConi™ etch to proceed more rapidly. Alternatively, reactive oxygen may be introduced during the SiConi™ etch further improving the effective etch rate.

Systems, methods, and apparatus for providing a fluid and reduced-toxicity optical media with optical analysis and therapeutic energy delivery. An aspect of the invention provides an aqueous solution of increased-salinity of between about 1% and 35%. An increasing salinity in accordance with the invention provides improved transmissive efficiency at many wavelengths and less toxicity than many existing systems and methods. A catheter having integrated fibers for probing or treating internal lumens or other tissues can include a liquid-inflatable balloon or flushing mechanism using the solution for displacing blood or other obstructions in an optical path between the fiber and targeted tissue. Methods including spectroscopy can be employed with the solution for diagnosing medical conditions associated with diseased vessels or other tissues while reducing the risk of permanent damage resulting from the diagnosis. Additional applications include the deliver of therapeutic radiation externally and internally to tissues through h the solution media.

System for trapping and stretching biomolecules. A microfluidic device includes a symmetric channel forming a T-shaped junction at a narrow center region and three wider portions outside the center region. At least one power supply is provided to generate an electric potential across the T-shaped junction to create a local planar extensional field having a stagnation point in the junction whereby a biomolecule introduced into the microfluidic device is trapped at the stagnation point and stretched by the extensional field.
