Abstract: A mobile, self contained molecular diagnostics system is provided with a microfluidic chip, detection apparatus and an integrated or wireless control interface and imager. The system provides automated sample preparation and rapid optical detection of multianalyte nucleic acids and proteins. On chip PCR may be performed to improve the optical fluorescence signal for nucleic acid detections. Plasmonic protein detection is performed using a dark field smartphone microscope. Dark field illumination is based on an evanescent field generated by LED total internal reflection. The smartphone element may also be used as an interface to control the detection apparatus, acquire images, process data and for wireless communications with remote computers. The handheld automated system has low power requirements and is particularly suited for point of care and on demand diagnostics in resource limited settings.

Abstract: An apparatus with a self-contained, tunable, microfluidic pumping system that utilizes the high air permeability of the matrix material to actuate fluid flow in a network of fluidic microchannels and microstructures is provided. The pumping relies upon partial evacuation of degas/vacuum channels that are located next to the fluid channels to degas air from the fluid channels or structures producing a reduction of pressure in the fluidic channel leading to the flow of fluid from an inlet at atmospheric pressure through the device. The solution is isolated from the pumping apparatus since the liquid does not pass through the diffusion barriers. The apparatus and method can also provide bubble-free microfluidic pumping, without any auxiliary equipment or device pre-treatment, and can fill dead-end channels and chambers, providing a powerful liquid handling tool for a broad range of applications.
Abstract translation: 提供了一种具有独立的,可调谐的微流体泵送系统的装置,其利用基质材料的高透气性来驱动流体微通道和微结构网络中的流体流动。 抽吸依赖于位于流体通道旁边的脱气/真空通道的部分抽空,以使来自流体通道的空气脱气,从而产生流体通道中的压力降低,导致流体从大气压下的入口流动通过 装置。 该溶液与泵送装置隔离,因为液体不通过扩散阻挡层。 该设备和方法还可以提供无气泡微流体泵送,无需任何辅助设备或设备预处理,并且可以填充死端通道和室,为广泛的应用提供强大的液体处理工具。

Abstract: A Digital Separation (DS) chip for separating, digitizing and analyzing a fluid sample is presented. The DS chip includes a fluidic layer that prepares and compartmentalizes the fluid sample for analysis. Cliff structures that are adjacent to wells skim the fluid sample and prevent particles, which may interfere with fluid sample analysis, from entering the wells. Skimmed fluid sample analysis occurs in the wells and endpoint data can be collected and used to determine an original concentration of a desired component in the fluid sample very quickly. Using the described apparatus and methods, a fluid sample can be prepared, digitized, compartmentalized, assayed and the endpoint data collected in ˜30 minutes. The apparatus and methods can easily be adapted to provide parallel processing of a sample.
