Methods for localizing target molecules in a flowing fluid sample
First Claim
1. A device for concentrating and detecting target molecules in a flowing fluid sample, said device comprising:
- a housing defining a passage through which a fluid sample flows;
a concentrating device positioned in the housing and comprising at least one electrode on a first side of the passage, wherein the at least one electrode on the first side of the passage has a polarity which electrostatically attracts target molecules in the flowing fluid sample; and
a detection device downstream of the concentrating device and comprising test structures having capture probes that are capable of specifically binding to the target molecules, if any, in the flowing fluid sample, wherein said test structures are positioned in the housing on the first side of the passage.

Abstract
The present invention relates to a device and method for concentrating and detecting target molecules in a flowing fluid sample. The device includes a housing defining a passage through which a fluid sample flows and a concentrating device positioned in the housing and including at least one electrode on a first side of the passage. The at least one electrode on the first side of the passage has a polarity which electrostatically attracts target molecules in the flowing fluid sample. The device also includes a detection device downstream of the concentrating device and including test structures having capture probes that are capable of specifically binding to the target molecules, if any, in the flowing fluid sample. The test structures are positioned in the housing on the first side of the passage.

19. A method for concentrating and detecting target molecules in a flowing fluid sample, said method comprising:
-
providing a device comprising;
a housing defining a passage through which a fluid sample flows;
a concentrating device positioned in the housing and comprising at least one electrode on a first side of the passage, wherein the at least one electrode on the first side of the passage has a polarity which electrostatically attracts target molecules in the flowing fluid sample; and
a detection device downstream of the concentrating device and comprising test structures having capture probes that are capable of specifically binding to the target molecules, if any, in the flowing fluid sample, wherein said test structures are positioned in the housing on the first side of the passage;
introducing a sample containing target molecules into said device;
applying an electric field to the at least one electrode on the first side of the passage of the concentrating device under conditions effective to electrostatically attract and concentrate the target molecules, if any, in the flowing fluid sample near the at least one electrode on the first side of the passage of the concentrating device; and
permitting the concentrated target molecules in the flowing fluid sample to specifically bind to the capture probes of the detection device, wherein the presence of the target molecules in the flowing fluid sample is detected. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51)
