Abstract
Diagnostic devices, systems and methods for detecting the presence of an analyte in a sample are provided. In one embodiment, the device comprises a substrate, a binder printed in a pattern onto a surface of the substrate, and a means for directing a sample towards the surface of the substrate that is printed with the binder. Systems of the present invention further include a light source that can be directed through the aforementioned means or another opening to the binder-printed surface to test for diffraction.
Claims26
A device for detecting the presence of an analyte in a sample, the device comprising:
- a substrate,
- a binder printed in a defined pattern onto a surface of the substrate, and
- a guide that directs a sample towards the surface of the substrate that is printed with the binder.
A device for detecting the presence of an analyte in a sample, the device comprising:
- a substrate,
- a binder printed in a pattern onto a surface of the substrate, and
- a means for directing a sample towards the surface of the substrate that is printed with the binder.
A system for detecting the presence of an analyte in a sample comprising:
- a substrate,
- a binder printed in a pattern onto a surface of the substrate, and
- a means for directing a sample towards the surface of the substrate printed with the binder;
- and
- a light or other electromagnetic radiation source that is positionable so that the light or other electromagnetic radiation source can be directed to the surface of the substrate printed with the binder.
The system of claim 21, wherein the light source is a laser.
A disposable, diffraction-based diagnostic device for detecting the presence of an analyte in a sample comprising:
- a film,
- a first binder for a first analyte printed in a pattern on to at least a first portion of the surface of the film,
- a first means for directing at least a portion of a sample from a source of the sample towards the at least first portion of the printed surface of the film,
- a second binder for a second analyte printed in a pattern onto at least a first portion of the surface of the film, and
- a second means for directing at least a portion of a sample from a source of the sample towards the at least second portion of the printed surface of the film.
