Raman Spectroscopic Method Diagnoses Infection at the Point of Care
Millions of people worldwide die from infectious diseases each year, and the spread of these diseases poses a real threat to the survival of public health systems. How quickly health care institutions can be overburdened when an infection rapidly spreads was once again made clear during the current pandemic triggered by the SARS-CoV-2 virus. In addition, the sharp increase in the number of multidrug-resistant pathogens often makes it difficult to effectively treat patients with pharmaceuticals. Noninvasive optical technologies such as Raman spectroscopy could hold the key to quick diagnoses and tailored patient treatment, helping to stop the spread of contagious diseases.

Expanding the Range: Wearables Enable the Next Level of Mobile Health Data Monitoring
The next generation of wearable devices will no longer be created only for the fitness-conscious to monitor their daily steps or heart rate on a smartwatch. Increasingly sophisticated photonic components such as LED arrays and specialized lasers, as well as a gamut of sensors and detectors contained within mobile equipment attached to the body, will be able to monitor spectral data within both the visible and infrared ranges.

Photoacoustic System Enables Real-Time Neurovascular Imaging
A photoacoustic imaging tool accommodates the need for speed and comprehensive detail in neurovascular imaging. The imaging modality enables an approach to visualize whole-brain hemodynamics and oxygenation in real time. It also tracks fast pathophysiological activities at the micro-vessel level. The approach breaks speed and resolution barriers in brain imaging technologies, and could lead to insights into stroke, dementia, and acute brain injury.

Noninvasive Imaging Method Measures Below the Diffraction Limit
A label-free microscopy technique developed by researchers at the University of Graz enables noninvasive, sub-diffraction-limit imaging of nanostructures. The all-linear, optical far-field measurement and imaging technique measures the position and size of nanoparticles with nanometer precision, even when the particles are adjacent.

Safe, Ingestible Fluorescent Silk Tags Authenticate Medications
To help block the flow of counterfeit medications, researchers at Purdue University and the National Institute of Agricultural Sciences in South Korea developed edible fluorescent tags that can be coded and added to pills or liquid medicine. Each tag is made from photoluminescent natural biopolymers and contains an imperceptible matrix code of information about the pharmaceutical. The code can be read with a smartphone app.

Sub-Cellular Biology at Tissue Scales with Cleared Tissue Axially Scanned Light-Sheet Microscopy
Wed, Aug 17, 2022 1:00 PM - 2:00 PM EDT
Large-scale interdisciplinary efforts have worked to comprehensively catalog cellular architectures in health and disease. Kevin Dean Ph.D. shares on the scalable imaging platform, Cleared-Tissue Axially Swept Light-Sheet Microscopy (CT-ASLM), that helps further this research. The CT-ASLM leverages high-speed, aberration-free, remote focusing to achieve an isotropic resolution of approximately 300 nm-scale subcellular imaging with an unparalleled optical sectioning capacity and large field of view. The platform provides global tissue architectures as well as quantitatively detailed morphological and biochemical descriptions of the individual cells that compose tissues in health and in disease.
