Abstract

Systems and methods for collecting portions of a target sample are disclosed herein. A method for detecting the presence and/or properties of a target sample can include selectively collecting a portion of a target sample with a sample collector and detecting, with the sample collector, the presence of one or more properties of the microscopic portion of the target sample. The method also includes analyzing, with the sample collector, the one or more properties of the microscopic portion of the target sample. Based on the analysis, the method further includes reporting, from the sample collector, a real-time indication of the analysis of the one or more properties of the target sample. The method can also include at least partially removing the microscopic portion of the target sample from the sample collector. The methods and systems disclosed herein can be used, for example, in systems or environments directed to quality assurance, preventative maintenance, safety, hazard warnings, homeland security, chemical identification and surveillance, and/or other suitable environments.

Claims

1. A method for detecting the presence and/or properties of a target sample, the method comprising:

selectively collecting a microscopic portion of a target sample with a sample collector;

detecting, with the sample collector, at least one of the following—

a presence of the microscopic portion of the target sample in the sample collector; and

one or more properties of the microscopic portion of the target sample;

reporting, from the sample collector, an indication of the detection of the one or more properties of the microscopic portion of the target sample; and

at least partially removing the microscopic portion of the target sample from the sample collector wherein the sample collector is comprised of an architectural construct including spaced apart layers of matrix characterizations of a crystal.

2. The method of claim 1 wherein selectively collecting the microscopic portion comprises at least one of the following:

filtering individual molecules of the target sample through corresponding layers of the architectural construct;

absorbing individual molecules of the target sample between corresponding layers of the architectural construct;

reflecting the microscopic portion of the target sample between corresponding layers of the architectural construct;

drawing the microscopic portion of the target sample between corresponding layers of the architectural construct via capillary action; and

inducing a pressure gradient that at least partially urges the microscopic portion of the target sample between corresponding layers of the architectural construct.

3. The method of claim 1 wherein detecting with the sample collector comprises at least one of the following:

sensing a rate that the portion of the target sample loads between corresponding layers of the architectural construct;

sensing a depth that the portion of the target sample loads between corresponding layers of the architectural construct;

sensing at least one of a transmissivity, reflectivity, and refraction of the portion of the target sample between corresponding layers of the architectural construct; and

sensing a wavelength shift of the portion of the target sample between corresponding layers of the architectural construct.

4. The method of claim 1 wherein reporting an indication of the detection of the one or more properties of the portion of the target sample comprises:

emitting a radio signal with a nano-radio;

generating an electrical current;

providing a response to an interrogation signal; and

providing a signal to a separate collector portion in a network of collector portions.

5. The method of claim 1 wherein at least partially removing the portion of the target sample comprises at least partially removing the portion of the target sample with the same method as selectively collecting the portion of the target sample.

6. The method of claim 1 wherein the sample collector is a first sample collector in a network of multiple sample collectors, and wherein the method further comprises performing the steps of collecting, detecting, reporting, and removing with the multiple individual sample collectors.

7. The method of claim 1, further comprising analyzing the one or more properties of the microscopic portion to determine one or more corresponding characteristics of the target sample.

8. A method comprising:

collecting a microscopic portion of a target sample with a self-contained sensing component wherein the means for selectively collecting the portion of the target sample comprises an architectural construct including spaced apart layers of matrix characterization of a crystal that are configured to load individual portions of the target sample;

automatically sensing at least one property of the collected microscopic portion of the target sample with the sensing component; and

providing a real-time externally accessible indication of the at least one property from the sensing component.

9. The method of claim 8 wherein sensing the at least one property of the microscopic portion comprises:

detecting a presence of the portion of the target sample; and

analyzing one or more material properties of the target sample.

10. The method of claim 8, further comprising clearing at least a portion of the target sample from the sensing component and cyclically repeating the collecting, sensing, and providing an externally accessible indication.

11. The method of claim 8 wherein collecting a microscopic portion comprises collecting a molecular sized portion of the target sample, and wherein sensing the at least one property comprises sensing the at least one property from the molecular sized portion of the target sample.

12. The method of claim 8 wherein collecting a microscopic portion comprises accumulating a predetermined amount of the target sample sufficient to sense the at least one property of the target sample.

13. The method of claim 8 collecting a microscopic portion of the sample comprises collecting a microscopic portion of a sample in at least one of the following environments or systems:

quality assurance, preventative maintenance, safety and hazard warnings, homeland security, and chemical surveillance.

14. A system comprising:

means for selectively collecting a portion of a target sample, wherein the portion is a microscopic portion relative to a size of the target sample wherein the means for selectively collecting the portion of the target sample comprises an architectural construct including spaced apart layers of matrix characterization of a crystal that are configured to load individual portions of the target sample;

means for automatically detecting the presence of one or more properties of the collected portion of the target sample;

means for automatically analyzing the one or more properties of the microscopic portion of the target sample; and

means for reporting an instantaneous indication of the analysis of the one or more properties of the target sample.

15. The system of claim 14, further comprising means for removing the portion of the target sample from the means for selectively collecting the portion of the target sample.

16. The system of claim 14 wherein the each of the means for selectively collecting, means for automatically detecting, means for automatically analyzing, and means for reporting are part of a first sensor, and wherein the system further comprises:

a plurality sensors each having the same features as the first sensor; and

a controller configured to communicate with at least one of the sensors.

17. The system of claim 16 wherein the plurality of sensors are distributed throughout at least one of the following environments:

a public transportation system, a water supply or distribution system, a food production, packaging, or transport system, a natural gas pipeline distribution system, a medicine delivery system, and/or a chemical or pharmaceutical manufacturing system.

18. The system of claim 14 wherein the means for selectively collecting a portion of the target sample comprises means for accumulating one or more separate molecular-sized portions of the target sample.
