Abstract

The present invention relates to portable systems and devices, and corresponding methods, for detecting bioagents. In particular, the present invention provides systems, devices, and methods that utilize one or more of a sample preparation component, sample analysis component employing broad range primers, and sample detection component.

First claim

We claim:

1. A portable handheld device comprising: a handheld detector and a kit cartridge, said handheld detector comprising:
a) a sample preparation chamber configured for isolation of nucleic acids from a sample;
b) a sample analysis chamber configured for analysis of isolated nucleic acids;
c) a sample detection chamber configured for detection of the presence of or identify of a target molecule;
d) a sample input port;
e) a user interface for receiving processing instructions from a user;
f) a display;
g) a processor configured to display an identity of a bioagent on said display; and
h) a removable reagent cartridge input port; and
said kit cartridge comprising: a removable reagent cartridge comprising two or more broad range primers wherein said broad range primers hybridize to regions of nucleic acid that are conserved between two or more different organisms, and flank a variable region of nucleic acid that differs between said two or more different organisms; and
wherein said sample preparation chamber is in liquid communication with said sample input port and in liquid communication with said removable reagent cartridge in said removable reagent cartridge input port;
wherein said sample analysis chamber is in liquid communication with said sample preparation chamber and in liquid communication with said removable reagent cartridge in said removable reagent cartridge input port; and
wherein said sample detection chamber is in liquid communication with said sample analysis chamber and in liquid communication with said removable reagent cartridge in said removable reagent cartridge input port.

2. The portable handheld device of claim 1 , wherein said removable reagent cartridge comprises reagents for nucleic acid amplification.

3. The portable handheld device of claim 1 , wherein said removable reagent cartridge comprises reagents for nucleic acid sequencing.

4. The portable handheld device of claim 1 , wherein said sample preparation chamber comprises a SCODA gel.

5. The portable handheld device of claim 4 , wherein said device is configured to generate an electric field for SCODA separation of nucleic acids.

6. The portable handheld device of claim 4 , wherein said SCODA gel comprises immobilized broad range primers.

7. The portable handheld device of claim 6 , wherein said immobilized broad range primers amplify target nucleic acid.

8. The portable handheld device of claim 7 , wherein at least one of said immobilized broad range primers is a labeled primer.

9. The portable handheld device of claim 7 , wherein said identity of said bioagent is displayed without elution of said target nucleic acid from said SCODA gel.

10. The portable handheld device of claim 1 , further comprising a database of target nucleic acid sequences or base compositions for identifying an unknown target nucleic acid processed by said device.

11. A portable system comprising the portable handheld device of claim 1 .

12. The system of claim 11 , wherein said removable reagent cartridge comprises reagents for nucleic acid amplification.

13. The system of claim 11 , wherein said removable reagent cartridge comprises reagents for nucleic acid sequencing.

14. The system of claim 11 , wherein said sample preparation chamber comprises a SCODA gel.

15. The system of claim 14 , wherein said portable handheld device is configured to generate an electric field for SCODA separation of nucleic acids.

16. The system of claim 14 , wherein said SCODA gel comprises immobilized broad range primers.

17. The system of claim 16 , wherein said immobilized broad range primers amplify target nucleic acid.

18. The system of claim 17 , wherein at least one of said immobilized broad range primers is a labeled primer.

19. The system of claim 17 , wherein said identity of said bioagent is displayed without elution of said target nucleic acid from said SCODA gel.

20. The system of claim 11 , further comprising a database of target nucleic acid sequences or base compositions for identifying an unknown target nucleic acid processed by said system or device.
