NIR-II Looks Deep into the Research Realm
In vivo imaging in the second near-infrared biological window is in its early stages but will undoubtedly affect life science research on many levels, both in preclinical and clinical work and in universities and medicine. Research in biology and medicine will be fundamentally changed.

Diffuse Optics Filters Diagnoses
Diffuse optics and the study of light absorption and scattering in various tissues can track blood oxygenation and other factors that help assemble an accurate medical diagnosis. Light scatters multiple times when traveling through a thick tissue sample, hence the “diffuse” property of this technique. Diffuse optical imaging has been shown to be a reliable measure for evaluating the health and outcomes of patients undergoing cardiac surgery, metabolic treatment, and tests for cancer. Breast cancer, in particular, has been both a tangible and virtual target for these techniques.

Light Brings a Delicate Touch to Treatment
Almost as soon as the first working laser was built in 1960 by Theodore Maiman, reports from users of lasers multiplied regarding the curious effects that light can elicit on living tissue. In 1962, dermatologic surgeon Leon Goldman reported the successful laser removal of unwanted skin markings, specifically tattoos. Fast forward to today, and similar techniques are used to erase birthmarks and pigmentation as well.

SCAPE Microscopy Captures Image of Odor Detection
The olfactory system that lets mammals detect and identify odors starts with a wide array of G-protein-coupled receptors, which are located on olfactory sensory neurons that comprise the olfactory epithelium, a thin layer of tissue deep within the nose. This network has the capacity to identify and respond to the host of odors that mammals, including humans, come across every day.

LED Lighting for Fluorescence Microscopy: A Sustainable Illumination Option
Tue, Sep 22, 2020 10:00 AM - 11:00 AM EDT
This webinar, presented by Excelitas Technologies, will present the recent advancements in LED technology that have created an opportunity for LEDs to replace arc lamps for a variety of fluorescence imaging applications. Presenter Kavita Aswani, Ph.D., will address the development of high-power LEDs for the green excitation range, a wavelength that has traditionally been challenging for LEDs. She will also discuss the many advantages of using LEDs for microscopy systems in life sciences, including sustainability.
