Good diagnostics save lives. According to the WHO, diagnostics in developing countries should be A.S.S.U.R.E.D., i.e., Affordable, Sensitive, Specific, User-friendly, Rapid and Robust, Equipment-free, and Deliverable to end-users. Active microfluidics, such as lab-on-chip systems enable the performance of complex analysis but require a ‘driving’ system and auxiliary equipment. Passive microfluidic diagnostics, like Lateral Flow Assays, are simple in use and require no energy. They are not able to perform complex liquid handling steps required for many analysis protocols.
3D Printed Passive Flow Assay
The 3D-Flow Assay is made up of a porous body with precise spatial control over the internal surface chemistry. This novel concept is used to create 3D capillary flow channels and install mechanisms for chemical amplification and readout. The assay is entirely passive and enables complex and multiple testing as is demonstrated for the immunoglobin E (IgE) ELISA test.
Low cost and scalable manufacturing process
Equipment-free evaluation is possible for positive/negative diagnosis.
Independent of user expertise – no training required.
Complexity is not limiting – one technology and process for all wicking structures
with fluidic control elements
Passive – self-driven by capillarity
Fast development iteration
The Basic Manufacturing Process in 3 steps:
Step 1: Convert lab protocol(s) into a CAD-model of a 3D-assay
Step 2: Print the 3D-assay based on a porous medium and functional inks.
Step 3: Test the 3D-assay. If needed, optimize the CAD-model and re-print.
We are looking for a partner(s) with expertise in the development and sales of medical diagnostics and a strategic interest to develop complex assays either by collaboration or by patent/technology transfer.
