2012
A reliable home-based way to assess the language comprehension of very young typically developing children, as well as those with autism, is described. The method analyzes children's eye gaze while viewing side-by-side images but hearing an audio that matches only one image. Stimuli are designed with young participants in mind.

Here, we present a protocol to perform portable cellular aerosol exposures and measure cellular response. The method uses cells, grown at the air-liquid interface, mimicking in vivo physiology. Cellular response to copper nanoparticle aerosols was observed as oxidative stress through reactive oxygen species generation and cytotoxicity as lactate dehydrogenase release.

2014
The Portable Chemical Sterilizer (PCS) is a revolutionary, energy-independent, almost waterless sterilization technology for Army medical units. The PCS generates chlorine dioxide from dry reagents mixed with water on-site, at-will, and at point-of-use (PoU) in a plastic suitcase. The Disinfectant-sprayer for Foods and ENvironmentally-friendly Sanitation (D-FENS) and the Disinfectant for ENvironmentally-friendly Decontamination, All-purpose (D-FEND ALL) produce aqueous chlorine dioxide in a...

Presented here is a protocol for field identification of Matricaria chamomilla using a portable qPCR system. This easy-to-perform protocol is ideal as a method to confirm the identity of a botanical species at locations where access to laboratory equipment and expertise is limited, such as farms and warehouses.
FAQs
Total internal reflection keeps light traveling within the optical fiber or transparent waveguide rather than escaping at the guiding boundary. This confinement reduces transmission loss, so more of the source's illumination reaches the intended biological target. In a Portable Light Guide, that principle supports controlled delivery despite the device's compact form and use outside a conventional laboratory setup.
A shaped coupling element helps transfer light from its source into the guide and can influence how efficiently illumination enters the transmission path. Together with the fiber or waveguide, it determines how much light is retained during delivery. This component is therefore important when the device must provide targeted illumination while keeping the overall system small and portable.
Flexible positioning allows the guide to reach confined locations or mobile biological systems without requiring the sample to remain in a conventional laboratory arrangement. A design that can contact a biological sample can place illumination close to the target, while noncontact positioning may preserve separation. These choices determine how access and targeting are balanced in a bioengineering setup.
Unlike illumination limited to a conventional laboratory setup, a Portable Light Guide is designed for controlled delivery in compact, mobile, or field-ready arrangements. Its small size and targeted output can improve access to confined biological systems. The distinction is therefore mainly operational: portability and placement expand where illumination can be applied, rather than changing the underlying optical principle.
A basic workflow begins by coupling a light source to the guide, positioning the fiber, waveguide, or shaped coupling element, and directing the output toward the selected target. The user then maintains the intended placement during illumination or measurement. This arrangement supports controlled exposure and can be adapted for contact with biological samples or for confined locations.
Portable light guides can support tissue illumination, optical sensing, microscopy, phototherapy, and light-activated experiments. The same compact delivery approach serves different purposes: it can provide light for observing or sensing biological material, or deliver illumination when light itself is part of an intervention or experimental trigger. Selection depends on the target and the intended optical task.
They are relevant because bioengineering often needs optical access to biological systems that are confined, mobile, or outside standard laboratory environments. A compact guide can connect targeted illumination with point-of-care tools and field-ready research platforms. This portability may support experiments and measurements where a larger conventional setup would be difficult to position or transport.
