FEATURES
Fluorescence Imaging Deepens the View: From Single Cells to the Subcellular The human body is made up of trillions of cells, and each one is as unique as the person it is part of. Each individual cell is arranged alongside its neighbors in a specific pattern that is...
Hyperspectral Imaging Characterizes Healthy and Diseased Tissues During Surgery Upgrades in medical imaging technology have made possible the accurate diagnosis and successful treatment of ailments ranging from broken bones to cancer. Techniques such as endoscopy keep evolving...
QCL-IR Microscopy: Delivering Molecular Information at Unprecedented Speed As microspectroscopic imaging applications have expanded, analytical scientists have demanded advancements from existing imaging technology. Such advancements are particularly critical for biomedical...
AI Bridges the Gap Between Medical Imaging and Analysis Improvements in the automation of functional mechanical, electrical, and optical components — along with increasing computing power for image analysis — have enabled the development of...
EDITORIAL
AI brings swift diagnosis Medical imaging modalities are now faster and more powerful than ever before, capturing thousands of images of diseased and healthy tissue. These images represent a vast resource for researchers and clinicians who track the progression of viruses or other illnesses under a microscope. The images reveal cellular dynamics that have developed within the patient, as well as similar changes in samples...

Laser Speckle Method Captures Blood Flow in Microvasculature Researchers at the National University of Singapore developed a confocal laser speckle autocorrelation method to image dynamic flow in microvasculature. The technique is label-free and enables real-time and quantitative imaging of blood flow on the microscopic level. The system shares many characteristics of a confocal fluorescence microscope; like the confocal fluorescence microscope, it is able...
Fluorescent Dye-Based Device Could Help Prevent Tooth Decay An optical device in development at the University of Washington (UW) could help prevent tooth decay by identifying at-risk teeth before cavities have had a chance to start to develop. The prototype,...
Committee Releases Draft of OCT Guidelines, Standards Representatives from the business and research sectors have developed a first draft of guidelines with standardized process descriptions for optical coherence tomography (OCT). The VDI/VDE Society...
Lensless Camera Captures Cellular-Level Details in 3D Rice University researchers have tested a tiny lensless microscope called Bio-FlatScope, capable of producing high levels of detail in living samples. The team imaged plants, hydra, and, to a limited...
Transparent Chip Provides View to Multimodal Imaging A transparent, biocompatible ultrasound transducer chip developed by researchers from Penn State is opening opportunities in cell and tissue stimulation and multimodal imaging. The chip, called a...
Method Keeps Liquid Marbles Functional for Microfluidic Systems A research team from Griffith University developed a technique that uses condensation to noninvasively refill liquid marbles with water. The method could improve the viability of applications such as...
Optica Names 2022 Award Winners for Service in Photonics Optica has announced 20 recipients of its 2022 awards and medals. The awards celebrate individuals who have achieved significant technical, research, education, business, leadership, and service...
Rescue Act Funds AIM Photonics' Production of Lab-on-Chip Tests The U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) has earmarked more than $10 million for photonic technologies addressing the ongoing pandemic. More than...

Thin Film Allows Metasurface Lens to Change Focus A research team headed by Christopher Dirdal from SINTEF Smart Sensors and Microsystems in Norway has created a metasurface lens that uses a piezoelectric thin film to change focal length when a...
TRUMPF Acquires Majority Stake in Active Fiber Systems TRUMPF has acquired an 80% stake in Active Fiber Systems GmbH (AFS), a company based in Jena, Germany. AFS develops and manufactures ultrashort-pulse laser systems and fiber laser systems used...
Kinetic River Advances Compensation-Free Flow Cytometry Kinetic River Corp. reported that it has advanced its Arno technology for time-resolved cell analysis, developing technology that enables compensation-free, 12-marker flow cytometry assays with just...
Three-Photon Microscopy Reveals Immune Cell Behavior in Real Time A research group from Cornell University has used three-photon microscopy to image the full depth of the popliteal lymph node in a living mouse — reportedly for the first time. The researchers...
3 QUESTIONS
3 Questions with Keith Paulsen BioPhotonics spoke with Keith Paulsen, the Robert A. Pritzker Professor of Biomedical Engineering at Dartmouth College’s Thayer School of Engineering. Paulsen and his colleagues recently published a paper about the use of a deep learning algorithm to accelerate the reconstruction of tissue images by combining scans from MRI together with diffused optical signals from near-infrared spectral...

The lack of standard metrology tools impedes the pace of microfluidics development Medical imaging modalities are now faster and more powerful than ever before, capturing thousands of images of diseased and healthy tissue. These images represent a vast resource for researchers and clinicians who track the progression of viruses or other illnesses under a microscope. The images reveal cellular dynamics that have developed within the patient, as well as similar changes in samples...

The butterfly effect Tiny changes can make a large difference in the way the world develops. This is known in chaos theory as the “butterfly effect,” a concept that may be easy to understand when it comes to how human behaviors — whether a gesture, a decision, or a habit — can affect other people. But it’s more difficult to grasp on the deeper biological level of cells, proteins, and...
