Lab-Grade Sensitivity, Pocket-Sized Diagnosis.

Dual-flow Lab-on-a-Chip diagnostics with AI-assisted smartphone readout. Under 15 minutes, under $1 per test, no laboratory required.

Built on UC-licensed IP
100% US-Owned
Targeting WHO TPP Compliance
Problem

Tuberculosis Remains
a Leading Global Killer.

The only WHO-endorsed urine-based POC test detects only 40 to 50% of cases,
restricting it to severely immunocompromised HIV-positive patients.

our technology

One Sample. Two Flows.
Lab-Grade Results.

A vertically stacked dual-flow architecture that delivers enzyme-amplified,
naked-eye-readable results from a single user step. No reader, no lab, no compromise.

01
Vertically stacked dual-flow architecture
PVDF delay pad creates a ~5-minute timing offset for sequential, time-differentiated reaction in a single user step.
02
Enzyme-amplified colorimetric signal
HRP + TMB chemistry produces an intense blue signal proportional to LAM concentration, readable by the naked eye.
03
scFv-HRP fusion antibodies
Produced in Pichia pastoris, eliminating batch variability and chemical conjugation cost.
04
AI-assisted smartphone quantification
QR-anchored homography + ratiometric T/C normalization handles variable ambient lighting on any phone.

Roadmap

From the Lab
to Global Health Impact.

An aggressive but staged path: non-dilutive funding first, regulatory clearance second, deployment third.

2026 Q2
Non-Dilutive Funding

Pursuing Bill Gates Foundation Grand Challenges, NIH SBIR Phase I, and Ohio TVSF programs.

2026 Q3-Q4
Platform Optimization

Reagent stabilization for ≥12-month shelf life (10-37°C); scFv-HRP fusion antibody scale-up.
F programs.

2027
Regulatory

FDA Q-Submission, Class II 510(k) or De Novo path, CLIA Waiver design.

2028+
Commercialization

LMIC field deployment via WHO/Pasteur/CDC channels; US clinical rollout via Razor & Blade model.
