Diffuser Modulation Enables Quantitative Lensless Microscopy
Traditional optical microscopes require constant adjustments to bring a sample into focus. To see a small feature with details, researchers must use a high-resolution objective lens with a reduced field of view. The trade-off between resolution and imaging area is a major inconvenience for life scientists and pathologists who rely on microscopy to analyze and diagnose disease, because prepared tissue samples have dimensions in the centimeter range. It turns out, however, that this inherent limitation can be overcome by using lensless equipment. Rather than using lenses to magnify the object image, a thin diffuser can be placed between the specimen and the image sensor in a lensless setting. The diffuser is then randomly scanned to various positions while the sensor acquires the images.

Achieving Improved Signal-to-Noise Ratio in Flow Cytometry
Flow cytometry explores, analyzes, counts, and sorts small particles. With the increasing demands for higher data quality from researchers, clinicians, and manufacturers, component builders for these systems are being driven to increase the signal-to-noise ratio (SNR), rather than just the signal. SNR is a widely applicable engineering term referring to the relative size of the real signal (or signal variations) compared to random errors (noise) in the observed signal.

UV Light and Riboflavin Reduce SARS-CoV-2 Pathogens in Plasma, Whole Blood
Researchers at Colorado State University (CSU) showed that exposure to riboflavin and ultraviolet light (R + UV) can reduce SARS-CoV-2 infectivity in human plasma and whole-blood products while maintaining blood product quality. The CSU team aimed to determine whether it would be possible to kill the virus in blood products. Although scientists do not yet know if SARS-CoV-2 can be transmitted by blood transfusion, viral RNA has been detected in serum.

Photosensitizer Design Absorbs Low-Energy Light, Transfers Energy Efficiently
Researchers at Hokkaido University, working with colleagues in Japan to develop a photosensitizer design that could use low-energy light effectively, developed a design that made the rare earth element europium (Eu) shine five times more brightly than any previous design. Their discovery could lead to more efficient photosensitizers with a wide variety of applications.

An Oblique Plane Light-Sheet Microscope with 200-nm-Scale Resolution
Tue, Aug 4, 2020 1:00 PM - 2:00 PM EDT
In this webinar, UT Southwestern professor Kevin Dean will describe an oblique plane microscope that uses a newly developed glass-tipped objective and an optimized optical train to maximize the speed, field of view, and resolution of the overall imaging system. He will characterize the performance of this microscope, and then demonstrate biological imaging of clathrin-mediated endocytosis, cell migration, natural killer cell induced cytotoxicity, and more. This webinar is sponsored by Applied Scientific Instrumentation; Andor Technology, part of the Oxford Instruments Group; TOPTICA Photonics; and Coherent Inc.
