摘要:
A method of analyzing pulses from a flow cytometer in which particles in a fluid pass through an excitation volume of an electromagnetic radiation and interact with the electromagnetic radiation to generate signals in the form of pulses includes generating a time-dependent pulse indicative of the characteristics of one or more particles passing through the excitation volume of the electromagnetic radiation, determining a measurement window by selecting a portion of the pulse with a starting point and an ending point above a predetermined value, and calculating a first derivative of the pulse with respect to time over the measurement window.

Patient specific array-based assays are provided. A feature of the subject patient specific array-based assays is that they include a step of interrogating a set of array features that have been previously identified by a general array-based assay to be relevant to a specific disease and condition of the subject being assayed. Also provided are methods of producing the subject patient specific array-based assays, as well as compositions and kits for use in practicing the subject assays.

The invention provides a method for controlled fabrication of a solid state structural feature. In the method, a solid state structure is provided and the structure is exposed to an ion beam, under fabrication process conditions for producing the structural feature. A physical detection species is directed toward a designated structure location, and the rate at which the detection species proceeds from the designated structure location is measured. Detection species rate measurements are fit to a mathematical model, and the fabrication process conditions are controlled, based on the fitted detection species rate measurements, to fabricate the structural feature.
摘要:
The present invention provides an apparatus for detecting a nanoscale moiety and a method for sensing a nanoscale moiety. The apparatus includes a substrate having a nanopore, at least one excitable molecule attached to the substrate adjacent to the nanopore, and a light source for exciting the excitable molecule attached to the substrate adjacent to the nanopore wherein the excitable molecule is quenched by the quencher molecule on the nanoscale moiety as it passes by the excitable molecule. The invention also includes a method for detecting the presence or identity of the nanoscale moiety.
