Abstract: Described here is an automated robotic device that isolates circulating tumor cells (CTCs) or other biological structures with extremely high purity. The device uses powerful magnetic rods covered in removable plastic sleeves. These rods sweep through blood samples, capturing, e.g., cancer cells labeled with antibodies linked to magnetically responsive particles such as superparamagnetic beads. Upon completion of the capturing protocol, the magnetic rods undergo several rounds of washing, thereby removing all contaminating blood cells. The captured target cells are released into a final capture solution by removing the magnetic rods from the sleeves. Additionally, cells captured by this device show no reduced viability when cultured after capture. Cells are captured in a state suitable for genetic analysis. Also disclosed are methods for single cell analysis. Being robotic allows the device to be operated with high throughput.

Abstract: There are many inventions described and illustrated herein. In one aspect, the present invention is directed to a technique of, and system for inspecting integrated circuits, including, for example, patterns projected, provided or formed on a wafer using photomasks, or patterns on the photomask itself. The inspection system and technique of this aspect includes first identifying, determining and/or detecting areas and/or patterns that are potentially defective by removing, filtering and/or eliminating from a set of potential defects any and/or all typical, regular or normal patterns. The identification, determination and/or detection of potential defects may be performed relatively quickly by a rapidly executing algorithm. In this way, a first or “coarse” analysis is performed rapidly and some, many, all or substantially all of the regular, normal or typical patterns are eliminated from further analysis. Thereafter, a second more detailed analysis is performed.

Abstract: A method and apparatus for selectively applying a print material onto a substrate for the synthesis of an array of oligonucleotides at selected regions of a substrate. The print material includes a barrier material, a monomer sequence, a nucleoside, a deprotection agent, a carrier material, among other materials. The method and apparatus also relies upon standard DMT based chemistry, and a vapor phase deprotection agent such as solid TCA and the like.

Abstract: An electron source includes a negative electron affinity photocathode on a light-transmissive substrate and a light beam generator for directing a light beam through the substrate at the photocathode for exciting electrons into the conduction band. The photocathode has at least one active area for emission of electrons with dimensions of less than about two micrometers. The electron source further includes electron optics for forming the electrons into an electron beam and a vacuum enclosure for maintaining the photocathode at high vacuum. The photocathode is patterned to define emission areas. A patterned mask may be located on the emission surface of the active layer, may be buried within the active layer or may be located between the active layer and the substrate.
