Abstract

A photo-spectroscopic analytic device is given for detecting analytes in a sample. The analyte may be microbial pathogen, a food sample, a sample of a body fluid, water, or a combination thereof. The device comprises an electromagnetic radiation (EMR) source in operative communication with one or more optic inputs, one or more receptors for receiving one or more sample holders, each receptor comprising one or more of the optic inputs which are operatively coupled to one or more optic outputs thereby forming an optic input-optic output pair. Each of the receptors may comprise different cross-sectional profiles corresponding to cross-sectional profiles of the sample holders.

Claims

1. A device for obtaining information for one or more analytes in a sample, comprising,

an electromagnetic radiation (EMR) source operatively coupled to a power source, the EMR source in operative communication with one or more optic inputs, each of the one or more optic inputs emitting one or more wavelengths of EMR,

one or more receptors for receiving one or more sample holder, each of the one or more receptors comprising one or more of the one or more optic input operatively coupled to one or more optic output thereby forming an optic input-optic output pair, each of the optic input-optic output pair receiving one or more wavelengths of EMR,

a detector operatively coupled with each of the one or more optic output, the detector for measuring transmitted or reflected EMR received from a sample when placed in the sample holder and the sample holder placed within the receptor, the detector producing a signal output comprising the obtained information.

2. The device of claim 1 further comprising a processing system operatively coupled to the signal output, the processing system comprising one or more calibration algorithms for detecting the identity, concentration or a combination thereof of the one or more analytes in the sample.

3. The device of claim 2, wherein the processing system is operatively coupled to the signal output via a hard wire connection.

4. The device of claim 2 wherein the device further comprises a transmitter that receives the output signal and transmits the output signal via a wireless connection to a processing system.

5. The device of claim 2 further comprising a screen for displaying a result obtained from the processing system the result comprising the identity concentration, or a combination thereof of the one or more analytes in the sample.

6. The device of claim 1 wherein the device is portable, or hand-held.

7. The device of claim 1 wherein each of the one or more receptors comprises a different cross-sectional profile, and each of the cross-sectional profiles of the receptors corresponds to a corresponding cross-sectional profile of the sample holder.

8. The device of claim 1 wherein the detector comprises one or more pixels, each of the one or more pixels comprising a photodetector with a single-layer thin film, the thin film having a known absorption coefficient.

9. The device of claim 1 wherein each of the one or more receptors is shaped to receive one or more sample holders, each sample holder having a different cross-section profile, the one or more receptor further comprising one or more selection mechanism to activate a pre-set one or more wavelength of EMR to pass through a sample when the one or more sample holders is inserted within the receptor.

10. The device of claim 1 wherein the one or more receptors is shaped to receive one or more sample holders, each sample holder comprising a plurality of sample wells, each of the one or more optic input-optic output pairs within the one or more receptors positioned within the receptor to align with each of the plurality of sample wells of the sample holder when the sample holder is inserted into the receptor.

11. The device of claim 2, wherein each of the one or more receptors is configured to direct the one or more wavelengths of EMR towards each sample contained in each one or more sample holder based upon an identifier associated with each of the one or more sample holders.

12. The device of claim 2, wherein the device is configured to apply an identifier to each of the one or more sample holders inserted in the device;

and reject sample holders that have been previously presented to the device.

13. A method for identifying one or more analyte in one or more sample, the method comprising, inserting each of the one or more sample into one or more sample holders, placing each of the one or more sample holders within each of the one or more receptors of the device of claim 2, and identifying the one or more analyte in the sample.

14. The method of claim 12, wherein the one or more analyte is a pathogen, a bacteria, or a compound.

15. The methods of claim 12, wherein the sample is a biological or non-biological fluid, a biological or non-biological semi-solid, or a biological or non-biological solid, a water sample, a sample of whole blood, serum, plasma, urine, synovial fluid, lymphatic fluid, sputum, feces, cerebrospinal fluid, a dairy product, milk, cheese, yogurt, ice cream, wine, a beverage, or semi soft food.
