A method and a device for modifying the energy-applying surface of an ultrasonic welding horn to join two complex thermoplastic parts by applying a thin film to the surface of the horn is disclosed. The thin film is applied to insure that a proper weld occurs along a complex and intricate pattern of energy directors located between the parts.

A microfluidic device may include a sample distribution network including a plurality of sample chambers configured to be loaded with biological sample for biological testing of the biological sample while in the sample chambers, the biological sample having a meniscus that moves within the sample chambers during loading. The sample distribution network may further include a plurality of inlet channels, each inlet channel being in flow communication with and configured to flow biological sample to a respective sample chamber, and a plurality of outlet channels, each outlet channel being in flow communication and configured to flow biological sample from a respective sample chamber. At least some of the sample chambers may include a physical modification configured to control the movement of the meniscus so as to control bubble formation within the at least some sample chambers. At least some of the sample chambers may include a dried reagent positioned within the at least some sample chambers proximate the inlet channels in flow communication with the at least some sample chambers.

Methods and devices are disclosed for microarray analysis. In one embodiment a method is disclosed for processing a non-standard size slide having an array of chemical compounds attached to a surface of the slide. A sample is exposed to the surface of the non-standard size slide wherein components in the sample bind to the chemical compounds on the surface of the slide. The sample and the slide are incubated under conditions for carrying out the binding reactions, and the surface of the non-standard size slide is examined for the results of the binding reactions. Prior to the exposing step or the incubating step or the examining step, the non-standard size slide is placed into a slide holder comprising a slide-holding section a slide-holding section adapted to dispose the non-standard size slide to a processing instrument in a manner similar to that for a standard size slide. The non-standard size slide may also include an identifier such as a bar code.
摘要:
A method of testing multiple fluid samples with multiple biopolymer arrays. A cover is assembled to a contiguous substrate carrying on a first side, multiple arrays each with multiple regions of biopolymers linked to the substrate, such that the cover and the substrate together form a plurality of chambers each containing a biopolymer array and each being accessible through its own port. Multiple fluid samples are introduced into respective chambers through a port of each such that the fluid samples contact respective arrays. A binding pattern of the arrays is observed. An apparatus and kit useful in such methods, are also provided.

摘要:
A test zone is read. Conjugate material is exposed to a sample. The conjugate material, when conjugated with at least one analyte in the sample, forms either electrically detectable conjugated material or magnetically detectable conjugated material. Conjugated material in the sample is captured in a test zone. A test is performed on the conjugated material captured in the test zone in order to detect analyte in the sample. The test is an electrical measurement, or a magnetic measurement.
摘要:
The invention provides methods of analyzing a sample. In general, the methods involve: a) depositing sub-fractions of a multi-dimensionally fractionated sample into wells of a multi-well substrate; b) contacting each of the deposited sub-fractions with an array to produce a set of sub-fraction-contacted arrays; and c) interrogating the sub-fraction-contacted arrays to identify a sub-fraction containing a post-translationally modified analyte. Also provided are systems and kits for performing the subject methods.
摘要:
A method of reading an array of moieties such as polynucleotides (for example, DNA) on at least a portion of a surface of a transparent slide which is opposite a first portion on the opposing surface, which array has been previously exposed to a sample. The method may include mounting the slide on a slide holder and retaining the slide thereon in a mounted position in which the holder does not contact the previously exposed array. The holder is then inserted into an array reader and the array read. A holder and slides which can be used in the method are also provided.
摘要:
A method is described for removing residue from a fluid deposited on the interior surface of an inkjet printhead after the printhead has contained or dispensed the fluid at least once. The method makes use of a reverse flushing technique optionally used in combination with sonication. A cleaning station for flushing an inkjet printhead with a wash fluid, rinse fluid, and/or inert gas is provided as well.
