Method of cleaning quartz substrates using conductive solutions

Abstract: A cleaning method for a quartz substrate includes mixing a rinsing solution and mixing a cleaning solution such that the solutions are electrically conductive. The rinsing solution is carbonated and is used in more than one step within the method. The cleaning solution includes ammonium hydroxide. As a result of the electrical conductivity of the solutions, the cleaning method is less susceptible to surface damage caused by electrostatic discharge. The sequence of steps includes rinsing the quartz substrate with the carbonated rinsing solution, removing loose contaminants by a high pressure application of the cleaning solution, and removing organic contaminants in a strong oxidation environment using a solution of sulfuric acid and hydrogen peroxide. The carbonated rinsing solution is again applied, followed by another high pressure application of the cleaning solution and a final rinse with the carbonated rinsing solution. In the preferred embodiment, the cleaned quartz substrate is used to form a laser ablation mask by depositing dielectric layers that are patterned to define an exposure pattern. In the most preferred embodiment, the laser ablation mask is used in the fabrication of inkjet printheads.

System for isolating biomolecules from a sample

Abstract: The present invention provides an automated system for purification of a substance of interest. The system generally comprises an instrument for moving fluids through the system, a reagent pack for storing fluids, and a purification cartridge. The cartridge comprises two filtration units for binding substances based on different physical properties. The cartridge also comprises rotary valves for control of movement of fluids on the cartridge. In preferred embodiments, the system is useful for purifying RNA from blood samples.

Micro-switch heater with varying gas sub-channel cross-section

Abstract: An apparatus for separating a liquid in a liquid metal micro-switch. In representative embodiments, the apparatus comprises a heater and a sub-channel inside a structure. The heater is located inside a cavity of the structure onto which the liquid metal micro-switch is fabricated. The sub-channel inside the structure connects the cavity to a main channel. The sub-channel has a cross-sectional area. The value of the cross-sectional area at the boundary between the sub-channel and the main channel is less than the value of the cross-sectional area at the boundary between the sub-channel and the cavity. The gas permeates the cavity and the sub-channel and is capable of extending into the main channel.
