We present a magnetic levitation technique coupled with automated imaging and analysis in both a smartphone-compatible device and a device with embedded imaging and processing. This is applied to measure the density distribution of cells with two demonstrated biomedical applications: sickle cell disease diagnosis and separating white and red blood cells.

Point of care ultrasound (POCUS) is increasingly being utilized in airway management. Presented here are some clinical utilities of POCUS, including differentiating endotracheal and esophageal intubation, identification of the cricothyroid membrane in the event a surgical airway is required, and measuring anterior neck soft tissue to predict difficult airway management. ...

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.

A simple microfluidic device has been developed to perform anesthetic free in vivo imaging of C. elegans, intact Drosophila larvae and zebrafish larvae. The device utilizes a deformable PDMS membrane to immobilize these model organisms in order to perform time lapse imaging of numerous processes such as heart beat, cell division and sub-cellular neuronal transport. We demonstrate the use of this device and show examples of different types of data collected from different model systems.

FAQs
Miniaturized illumination provides the light or excitation needed to reveal a sample, while optics direct and focus the resulting visual or molecular signal. An image sensor records that signal, and software converts the captured pattern into an interpretable image or quantitative result. This coordinated design allows measurements outside conventional laboratory systems.
The output depends on how the device captures and processes information from the sample, patient, or field environment. Light patterns may generate visual images, whereas molecular signals can be converted into measurements through software analysis. These different outputs allow the same general platform to support either direct visualization or biomarker assessment.
Minimal preparation reduces the handling required before imaging and makes measurements more practical when conventional laboratory infrastructure is unavailable. It can support faster use in clinics, field environments, and resource-limited settings, where complex preparation may delay interpretation. The resulting workflow is especially relevant when information is needed close to the time of testing.
A typical workflow places a biological sample, patient-related target, or field subject within the device’s imaging path, applies the available illumination or signal-detection approach, and records the response with the image sensor. Software then converts the captured information into an image or quantitative result. The approach can require minimal sample preparation.
In these fields, the devices can help visualize cells, pathogens, immune responses, or diagnostic biomarkers. Their value lies in bringing imaging or measurement closer to the point of care rather than restricting observations to conventional laboratory systems. This supports investigation of infection-related findings and immune activity in clinically or geographically constrained settings.
They are useful when testing or observation must occur in clinics, resource-limited settings, or field environments where conventional systems are impractical. By enabling visual or quantitative information to be collected near the testing site, they may support rapid surveillance and time-sensitive outbreak investigations. Their portability also broadens access to measurements during changing conditions.
