JAKE SALTZMAN, NEWS EDITOR [email protected]Researchers at Boston University introduced a multifocus optical microscopy technique for simultaneously acquiring images at differing depths. The method can be added to existing camera-based microscopy techniques, such as fluorescent, phase contrast, and dark-field imaging. The development will allow users to observe living cells and organisms at high speeds and with high contrast. Using a z-splitter prism that the research team led by Jerome Mertz assembled from off-the-shelf components, including partial beamsplitters and right-angle prisms, the researchers divided detected...Read full articleRelated content from Photonics MediaArticlesOptical Redox Imaging Monitors Heart Cell DevelopmentAn optical imaging tool for monitoring the growth of human heart cells known as cardiomyocytes (CMs) could lead to a reproducible means to generate human induced pluripotent stem cell-derived...BioPhotonics Nov/Dec 2024 IssueCytometer Detects Cancer Cell Subpopulations ConcurrentlyA new flow cytometry system could help scientists develop more targeted, personalized strategies for treating cancer by enabling them to follow disease progression and therapeutic response in...BioPhotonics Sep/Oct 2024 IssueMicroscopy Method Uses Infrared Light to Image Molecules with Vibrational ContrastThe complementary strengths of fluorescence and vibrational microscopy are combined in a new technique developed at Caltech, which is called bond-selective fluorescence-detected infrared-excited...BioPhotonics Sep/Oct 2023 IssueRaman Approach Safely Tracks Live-Cell RNA ExpressionSingle-cell RNA sequencing enables scientists to interrogate cells at extraordinary resolution and scale.
