    摘要: Embodiments of an apparatus, system, and method for chemical synthesis and/or analysis are disclosed. One embodiment of a disclosed apparatus comprises a laminated, microfluidic structure defining a reactor and a separator. Such apparatuses, or portions thereof, generally have dimensions ranging from about 1 micrometer to about 100 micrometers. To implement synthetic processes, disclosed embodiments of the apparatus generally include at least one valve, and often plural, selectively actuatable valves. Detectors, including optical detectors, also can be used to detect product and other materials as they flow by, or are otherwise presented to, the detector. Individual apparatuses may be coupled both in series and in parallel to form a system for making chemical compounds. The apparatus is particularly useful for making compounds requiring iterative reaction schemes, and further can be used to make compounds having morphological structures that resemble the morphology of the apparatus itself, such as dendrimers.

    摘要: The present invention comprises devices and methods for performing channel-less separation of cell particles by dielectrophoresis, DC high voltage-pulsed electronic lysis of separated cells, separation of desired components from crude mixtures such as cell lysates, and/or enzymatic reaction of such lysates, all of which can be conducted on a single bioelectronic chip. A preferred embodiment of the present invention comprises a cartridge (10) including a microfabricated silicon chip (12) on a printed circuit board (14) and a flow cell (16) mounted to the chip (12) to form a flow chamber. The cartridge (10) also includes output pins (22) for electronically connecting the cartridge (10) to an electronic controller. The chip (12) includes a plurality of circular microelectrodes (24) which are preferably coated with a protective permeation layer which prevents direct contact between any electrode and a sample introduced into the flow chamber. The permeation layer also helps to reduce cell adhesion at field minima, and enables immobilization of specific antibodies for specific cell capture. Specific cells from various cell mixtures were separated, lysed, and enzymatically digested on the chip.
