The AptaSure™ platform

Molecular precision, point-of-care simplicity.

AptaSure™ brings engineered aptamer chemistry into a simple, instrument-free lateral-flow test — designed to identify dangerous infections in minutes, right where care happens.

01 // The building block

What is an aptamer?

Aptamers are short, synthetic nucleic-acid sequences that fold into precise three-dimensional shapes, letting them bind a chosen target — like a bacterial protein — with antibody-like specificity.

Because they're chemically synthesized rather than grown biologically, aptamers can offer advantages in stability, batch-to-batch consistency, and lower-cost manufacturing at scale — well suited to a test made in volume and used anywhere.

02 // How AptaSure works

A dual-aptamer lateral-flow assay for MRSA.

AptaSure™ MRSA detects pbp2a — the protein that makes Staphylococcus aureus methicillin-resistant — using a cognate pair of aptamers and gold-nanoparticle signal, read by eye like a rapid test.

AptaSure MRSA point-of-care test device — The AptaSure™ MRSA device — swab, snap the pre-measured buffer, and read the colorimetric C/T result in minutes. Still from the product preview video; swap for a final asset when ready.

STEP // 01

Capture

A gold-nanoparticle–labeled aptamer binds the MRSA marker protein pbp2a in the sample.

STEP // 02

Confirm

A second, cognate aptamer binds pbp2a at a different site — a two-point lock that drives specificity and reduces false reads.

STEP // 03

Read

The complex concentrates at the test line, producing a visible result in minutes — no instrument required.

03 // The first target

Why MRSA, and why speed.

Methicillin-resistant S. aureus is one of the most consequential healthcare-associated infections. Conventional identification relies on culture that can take 1–3 days — time in which patients are treated empirically.

A rapid, point-of-care answer is designed to support earlier, more targeted decisions — the kind of difference that matters for both patient outcomes and cost of care.

05 // Development & validation

Advancing through the FDA 510(k) pathway.

AptaSure™ MRSA is being developed with research and clinical partners, with assay optimization and specificity testing conducted during development. The program is advancing toward FDA 510(k) pre-market notification. State the current, accurate regulatory status and validation data here, reviewed by Dr. Lange.
