Improving the Sensitivity and Functionality of Mobile Webcam-Based Fluorescence Detectors for Point-of-Care Diagnostics in Global Health.

Diagnostics (Basel, Switzerland)

Rasooly R, Bruck HA, Balsam J, Prickril B, Ossandon M, Rasooly A.
PMID: 27196933
Diagnostics (Basel). 2016 May 17;6(2). doi: 10.3390/diagnostics6020019.

Resource-poor countries and regions require effective, low-cost diagnostic devices for accurate identification and diagnosis of health conditions. Optical detection technologies used for many types of biological and clinical analysis can play a significant role in addressing this need, but...

The National Institutes of Health Affordable Cancer Technologies Program: Improving Access to Resource-Appropriate Technologies for Cancer Detection, Diagnosis, Monitoring, and Treatment in Low- and Middle-Income Countries.

IEEE journal of translational engineering in health and medicine

Pearlman PC, Divi R, Gwede M, Tandon P, Sorg BS, Ossandon MR, Agrawal L, Pai V, Baker H, Lash TB.

IEEE J Transl Eng Health Med. 2016 Sep 08;4:2800708. doi: 10.1109/JTEHM.2016.2604485. eCollection 2016.

Point-of-care (POC) technologies have proved valuable in cancer detection, diagnosis, monitoring, and treatment in the developed world, and have shown promise in low-and-middle-income countries (LMIC) as well. Despite this promise, the unique design constraints presented in low-resource settings, coupled...

Previous research has shown that the autonomic nervous system provides essential constraints over ongoing cognitive function. However, there is currently a relative lack of direct empirical evidence for how this interaction manifests in the brain at the macroscale level....

Wavelength-scalable hollow optical fibres with large photonic bandgaps for CO2 laser transmission.

Nature

Temelkuran B, Hart SD, Benoit G, Joannopoulos JD, Fink Y.
PMID: 12478288
Nature. 2002 Dec 12;420(6916):650-3. doi: 10.1038/nature01275.

Conventional solid-core optical fibres require highly transparent materials. Such materials have been difficult to identify owing to the fundamental limitations associated with the propagation of light through solids, such as absorption, scattering and nonlinear effects. Hollow optical fibres offer...

External reflection from omnidirectional dielectric mirror fibers.

Science (New York, N.Y.)

Hart SD, Maskaly GR, Temelkuran B, Prideaux PH, Joannopoulos JD, Fink Y.
PMID: 11964473
Science. 2002 Apr 19;296(5567):510-3. doi: 10.1126/science.1070050.

We report the design and fabrication of a multilayered macroscopic fiber preform and the subsequent drawing and optical characterization of extended lengths of omnidirectional dielectric mirror fibers with submicrometer layer thickness. A pair of glassy materials with substantially different...
