Goal 1: Promote Human Health

Developing tools/algorithms for objective evaluation of sleep health

What are the best tools/algorithms for robust and objective evaluations of sleep health biomarkers?

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? Compelling Question (CQ)

Details on the impact of addressing this CQ or CC

Sleep deficiency is pervasive in today’s society and associated with an array of threats to health and public safety. The availability of a biomarker(s) for sleep health would turn-the-curve on developing practical and feasible ways to identify individuals at risk for sleep deficiency and prevent/manage associated risks to health and public safety on a large-scale.

Feasibility and challenges of addressing this CQ or CC

Sleep and circadian regulation is coupled to an array of behavioral, physiological and molecular/genetic processes to leverage in the development of biomarkers for sleep health.
Untreated sleep disorders and sleep deficiency pose a significant burden on health and public safety. There is currently no biomarker, or point-of-care technology available to objectively measure an individual’s level of sleep deficiency or susceptibility, a significant barrier to prevention and management.

Goal 3: Advance Translational Research

Point of care detection of rare cells in blood

Laboratory analyses at the bedside or in the hinterlands can reduce the cost and increase the capture of disease states in underserved populations. The injection of a blood draw directly into a portable device that requires no further operator interventions is a Critical Challenge. With today’s automated chemistry and a miniaturized flow cytometer this challenge could be met.

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? Critical Challenge (CC)

Details on the impact of addressing this CQ or CC

Although portable flow cytometers exist, they are not equipped with chemical automation and rare-cell enrichment capability. An integrated system could be applied to multiple diagnostic goals. A sufficiently versatile design should be able to detect and enumerate specific cell populations at any level (not only rare cells) in the circulation — T-cell subsets in AIDS, for example.

Feasibility and challenges of addressing this CQ or CC

Automated mixing and labeling, magnetic bioseparations, microfluidics, high-intensity LEDs and sensitive avalanche photodiodes can be combined to address this CC.
