Your Trusted OEM Partner for Precision Point-of-Need Assays

Ready to Take Your Assay Beyond the Lab? We can help.

Immunoassays are a valuable tool in many industries, ranging from human health to environmental monitoring, because they can provide accurate measurements. Unfortunately, most immunoassay users are faced with a trade-off between the sensitivity and specificity of laboratory enzyme-linked immunosorbent Assays (ELISAs) and the ease of use, speed, and low cost of lateral flow assays (LFAs) for point-of-care and point-of-need applications. Burst Diagnostics’ capillary-driven immunoassay (CaDI) technology solves this problem by providing the performance of a laboratory ELISA with the simplicity of an LFA.

  • CaDI has demonstrated >100x improved sensitivity over traditional LFAs without sacrificing cost-effectiveness, manufacturability, speed, or ease of use. 

    CaDI provides quantitative results using a sensitive chemiluminescent reader. CaDI has shown the ability to quantify as low as pg/mL concentrations.

  • CaDI delivers automated results in <10 minutes following a simple, one-step sample addition.

  • CaDI is capable of multiplexing up to four analytes within a single cartridge.

  • CaDI was designed with widely available, low cost materials and can be scaled to >20,000 devices per day.

  • CaDI has demonstrated capability on many sample matrixes including saliva, serum, urine, blood, swabs, and other aqueous solutions.

    CaDI supports both sandwich and competitive immunoassay formats and is compatible with a range of detection modalities, including chemiluminescent, colorimetric, and electrochemical readouts.

  • CaDI supports flexible readout options, including a standalone reader or laptop-based analysis and result display.

If there's an antibody for it, we can build it. CaDI is applicable anywhere that ELISAs are used and where real-time results will deliver valuable payback.

We’re Not A Traditional Rapid Test

Our team of scientists and engineers brings over 40 years of collective experience developing low-cost, high-performance assays. Whether you're looking to take your lab assay into the field or improve the sensitivity of your current rapid test, we can help you do both.

Our unique chemiluminescent platform, CaDI, is an automated, miniaturized ELISA initiated by a single sample addition step. Its novel design integrates each ELISA step into a <10-minute workflow.

A Faster ELISA

Lab-based enzyme-linked immunosorbent assays (ELISAs) are highly sensitive but slow, requiring trained personnel, costly equipment, and over several hours to deliver results.

CaDI condenses each step of an ELISA into a 10-minute, lab-in-your-hand format, making it over 20x faster than a lab-based ELISA. Powered by capillary action, CaDI automates each step of an ELISA (binding, washing, labeling, and amplification) with timed release and sequential delivery of reagents.

Say goodbye to long lab workflows. Say hello to real-time ELISA-like results from a one-step sample addition.

More Sensitive LFA

Traditional lateral flow assays (LFAs) lack the sensitivity and quantification capabilities that set CaDI apart. In traditional LFAs, reagents flow linearly and interact simultaneously at the test line, which restricts sensitivity and precision. This simple linear flow design prevents automated washing steps or the sequential delivery of enzyme amplification reagents that are critical for achieving higher sensitivity.

CaDI enables automated sequential delivery of reagents, including enzyme-driven amplification, from a single sample addition step. This design overcomes the core limitations of LFAs, dramatically increasing sensitivity >100x without adding complexity.
