摘要:
The invention relates to a method and a device for sorting microparticles (6) in a fluid flow (5) whereby a microparticle (6) is detected by means of a detection unit and an identification signal is generated when the microparticle (6) passes a detection area (7), and at a switching point (8, 9), which is selected depending on the identification signal, of a branching with at least one inlet (2) and at least two outlets (3, 4), the viscosity of the fluid (5) is decreased by means of irradiation with electromagnetic radiation for a predetermined period of time once a predetermined time span after the generation of the identification signal has elapsed such that the proportion of the portions of the fluid flow (5) passing through the at least two outlets (3, 4) is changed in such a way that the microparticle (6) is guided through the outlet determined by the identification signal.

A system for preparing samples for chemical analysis comprises at least one sample container, and a container receptacle apparatus for receiving the sample container. The sample container comprises an elongate tubular body having a crucible portion proximal to a closed end for receiving a sample therein, and an expansion portion proximal to an open end. The container receptacle apparatus comprising a housing having a heating compartment, a cooling compartment spaced apart from the heating compartment, and an insulating region located between the heating compartment and the cooling compartment. The heating compartment is shaped to receive the crucible portion of the sample container, and the cooling compartment is shaped to receive the expansion portion of the sample container. The apparatus also includes a heating mechanism for heating the sample within the crucible portion of the sample container, and a cooling mechanism for cooling the expansion portion of the sample container.

摘要:
A method and device for promoting induced thermal transduction in chemical and biochemical reactions is disclosed. In one preferred embodiment, a method of elongating a primer annealed to a DNA template is disclosed. This method comprises the first step of combining a radio frequency responsive support in an aqueous environment with a DNA template molecule, DNA primers, DNA polymerase, deoxynucleotide triphosphates and reagents necessary to amplify the DNA template. An electromagnetic field is then applied to the combination, wherein the temperature of the support will increase and the DNA template with become denatured. The electromagnetic field is removed and the temperature of the support decreases. The primer molecules anneal to the denatured DNA template and the DAN polymerase catalyzes elongation of the primer. In an especially preferred embodiment of the present invention, the support is derivatized so that the DNA template molecules are attracted to the surface of the support. The figure diagrams the relationship between PCR reagents, including the DNA template, primers and DNA polymerase, and the radio frequency responsive support.
