NIH has awarded a total of $1 million to six winners of the NIH Technology Accelerator Challenge for the design and development of non-invasive, handheld, digital technologies to detect and diagnose sickle cell disease (SCD), malaria, and anemia. Winners are listed below.
NTAC Challenge Winners - 2020
The proposal aims to develop a non-invasive, smartphone-based spectroscopy platform to detect anemia and SCD by analyzing photos of the microvasculature of the inner eyelid.
Saliva will be non-invasively collected and analyzed by multiplex lateral flow tests for detection of SARS-CoV-2-specific antigens, ferritin (a marker of iron deficiency), and a malaria parasite protein, PSSP17.
The smartphone-based Capillaroscopic Cytometer will non-invasively image thousands of capillary blood cells for cell classification, morphology, counting, and measurement of flow from a single video dataset.
Disease diagnosis is performed using a finger cuff to detect hemoglobin variants related to anemia and SCD, and hemozoin, a marker for the malaria parasite in blood.
A smartphone app and 3D printed attachment will be used in a saliva lateral flow assay using gold nanoparticles to capture markers for iron deficiency (ferritin), inflammation (CRP), and malaria (PSSP17).
The technology uses a picture of the fingernail beds and a smartphone app to evaluate anemia and screen for SCD with a novel algorithm.
This proposal will employ a smartphone-based device that uses laser pulses on the skin and ultrasound to detect rare circulating malaria and sickle cell disease-related cells.
