摘要: Methods and systems are provided for concentrating particles (e.g., bacteria, viruses, cells, and nucleic acids) suspended in a liquid. Electric-field-induced forces urge the particles towards a first electrode immersed in the liquid. When the particles are in close proximity to (e.g., in contact with) the first electrode, the electrode is withdrawn from the liquid and capillary forces formed between the withdrawing electrode and the surface of the liquid immobilize the particles on the electrode. Upon withdrawal of the electrode from the liquid, the portion of the electrode previously immersed in the liquid has particles immobilized on its surface.

摘要: The present invention provides devices and methods for measuring electrically detectable bulk properties of liquid samples. Representative electrically detectable bulk properties measurable by the devices and methods of the invention include resistivity (conductivity) and dielectric constant (permittivity). The electrically detectable bulk properties are determined by comparing the experimental electrical output of the devices with mathematically simulated models of the experimental devices.

摘要: An advanced high-resolution and high-throughput shadow edge (116) lithography (SEL) method is disclosed for forming uniform zero- one- and two-dimensional nanostructures on a substrate. The method entails high-vacuum oblique vapor deposition and a compensated shadow effect of a pre-patterned layer (100). A method of compensating for cross-substrate variation is also disclosed. The compensation approach enables routine, low-cost fabrication of uniform nanoscale features, or nanogaps (110) on the order of 10 nm±1 nm, that can be used to etch nanowells (196) or to form nanostructures such as nanowires (169), using a selective metal lift-off process. A wafer-scale analytical model is proposed for predicting the width of nanogaps (110) fabricated by the shadow effect on pre-patterned edges. By combining compensation and pattern reversal techniques with multiple shadow patterning, two-dimensional structures such as crossing nanowires may be generated. A technique is disclosed for smoothing edge roughness of the nanostructures.
