摘要:
Systems and methods for software-reconfigurable chemical process systems useful in a wide range of applications. Embodiments may include software control of internal processes, automated provisions for cleaning internal elements with solvents, provisions for clearing and drying gasses, and multitasking operation. In one family of embodiments, a flexible software-reconfigurable multipurpose reusable “Lab-on-a-Chip” or “embedded chemical processor” is realized that can facilitate a wide range of applications, instruments, and appliances. Through use of a general architecture, a single design can be economically manufactured in large scale and readily adapted to diverse specialized applications. Clearing and cleaning provisions may be used to facilitate reuse of the device, or may be used for decontamination prior to recycling or non-reclaimed disposal. In other embodiments, a flexible software-reconfigurable multipurpose reusable laboratory glassware setup may be realized, sparing talented laboratory staff from repetitive, complex, or low-level tasks occurring in analysis, synthesis, or smallscale chemical manufacturing.

An apparatus and method for chemical synthesis, the method includes accessing a recipe, the recipe including a sequence of one or more processing steps for the chemical synthesis. The processing steps including one or more steps. The recipe is executed by sorting the processing steps and executing the one or more selected steps prior to executing other steps. The chemical synthesis is monitored by providing status data, indicating a status of the execution and enabling input of control data to modify execution based on the status data or user-initiated modification. Information related to the status of the execution is displayed, typically as a graphical representation of a process action.

A microfluidic device and method is disclosed for fractionating and/or trapping selected molecules with a diffusion barrier or porous membrane. The device includes a source fluid flow channel and a target fluid flow channel. The target fluid flow channel and the source fluid flow channel meet at cross-channel area and are in fluid communication with each other. A porous membrane separates the source fluid flow channel from the target fluid flow channel in the cross-channel area. A field-force/gradient mechanism may be positioned proximate the porous membrane with or without detection/state monitoring devices.

摘要:
Methods for measuring biochemical reactions and analysis of reaction products by controlling dispersion of reagents within fluid streams such that the measuring of the biochemical reaction is substantially free of a measurable dispersion artifact. Controlling dispersion of reagents within fluid streams can include flowing multiple fluid streams each including reaction reagents into contact through a mixing region to laterally mix the fluid streams and then passing the merged, laterally mixed fluid stream through a controlled dispersion element to axially disperse the reaction reagents merged fluid stream. Controlling dispersion of reagents within fluid streams can include controlling flow rates of multiple fluid streams each including reaction reagents to create a concentration gradient that is substantially free of a measurable dispersion artifact. The biochemical reaction can occur in a microfluidic chip.
