iDiagnostics is based on iTIRF microarray technology, which implements rapid and accurate molecular diagnostic measurements using a handheld device and disposable cartridges that are well-suited for home use

iDiagnostics Application Development Kit

and uTIRF Biodetection Station

The early detection of cancer, cardiovascular and other diseases, preventing pandemics, and other healthcare tasks require a highly sensitive, accurate, rapid, and yet affordable molecular diagnostics. Eleven years of research at TIRF Labs have resulted in the development of such a technology: a handheld platform, named iDiagnostics, which is a thousand times more accurate than traditional methods, rapid and robust, and yet inexpensive.

The goal of TIRF Labs is to provide iDiagnostics to every family on the globe. This goal cannot be achieved by a single company; we envision a collective global effort from the diagnostics community using the Open Innovation Business Model, which will stimulate a flux of intellectual property (IP) in and out of the iDiagnostics project. TIRF Labs will be delighted to license the IP of other research groups and will offer the opportunity to license our own IP, in certain cases free of charge.

To facilitate all of the stages of this challenging project, from biomarker discovery, to clinical testing, TIRF Labs offers the uTIRF biodetection station and the Application Development Kit (ADK). Figs. 1 and 2 show the optical scheme and photos of uTIRF, the lightguide-based TIRF accessory, and manual microarrayer. Fig. 3 depicts the iDiagnostics handheld cradle, and reusable cartridges designed for the development stage. These products are available to all members of the diagnostic community, including academic, industrial, and government research groups. The NIH, FDA and CDC will be involved in the coordination of the collective efforts.

Two main products - the uTIRF biodetection station and the Application Development Kit (ADK) - create the foundation for the collective project. The uTIRF is a multifunctional  biodetection station, which is sensitive down to single molecules. It includes  lightguide-, prism-, and objective-based TIRF, a low light CMOS camera, three-color illuminator, and 1X, 4X, and 60X objectives. The iDiagnostics ADK consists of the iDiagnostics handheld cradle, cartridge blanks, manual microarrayer, and reagents kit.

TIRF Labs has already received numerous requests from research groups worldwide to supply these products. In the middle of 2018 we plan to start supplying these products along with experimental protocols. Several groups have already joined our project. We have incorporated their feedback and will incorporate future comments from our future customers in the next releases of the uTIRF and ADKs. We will supply advanced hardware, software, reagents, development tools, protocols, videos, and other  support to accommodate the requirements for different diagnostic applications.

The arrays of bioassays printed at the surface of iDiagnostics slides include assays for detecting protein, nucleic acid, metabolite  biomarkers. The arrays contain internal controls to ensure reliability and calibration. The cartridge is equipped with a 20-microliters flow cell, which encompasses the microarray. iDiagnostics requires no or minimum sample preparation. Whole blood can be analyzed after the addition of an anticoagulant. Simple sample preparation module is included in the cartridge;  additional space is reserved for more complex sample preparation modules as will be required for applications developed in the future.

      iDiagnostics is a novel molecular diagnostics platform based on real-time TIRF microarrays, which is supersensitive, accurate, and rapid, yet affordable for home use. If you are developing fluorescence, electro-chemi-luminescence (ECL), or bioluminescence bioassays for diagnosing or prognosing, we invite you to collaborate. We will help you to interface your assays with iDiagnostics platform and will be delighted to license your technology. Ask about uTIRF and iDiagnostics Application Development Kit (ADK).

   iDiagnostics features a novel type of real-time microarray that simultaneously detects protein, nucleic acid, and metabolite biomarkers. It requires no or minimal sample preparation and is capable of detecting from a single to several thousands of molecular markers in a 50-microliter sample of biological fluids, including whole blood. High sensitivity and the broad dynamic range of iDiagnostics covers the entire spectrum of clinically significant concentrations. Limit of Detection (LOD) for micro-RNA is ~10-18M.  For proteins and metabolites LOD depends on the assay; for certain antibody-based assays LOD is  ~10-15M.  

    Classical TIRF microarrays operate with small, sub-monolayer amounts of antibodies and DNA probes immobilized on the surface; fluorescence signal is small, a low light photodetector, e.g. EMCCD camera is necessary. In the patent-pending iDiagnostics technology the signal of TIRF arrays is enhanced by 3D encapsulation, which captures the excitation light and becomes an integral part of the lightguide. 3D encapsulation allows for using larger amounts of antibodies per unit area of bioassay spot.  The signal from such arrays is a thousand-fold greater than that in classical arrays. CCD cameras of cellphones are sensitive enough to detect the signal. iDiagnostics is ideal platform for interfacing antibody-based bioassays for detecting proteins and molecular beacon assays for measuring nucleic acids.  Visit website and contact us by email: for more information.
