Researchers at the Technical University of Munich have developed a nano-CT scanning technique. When coupled with a new staining technique, their nano-CT scanner can take extremely high-resolution scans of intact tissue samples, such as tumors. The new method allows clinicians to examine soft tissue samples without the need for sectioning or toxic stains. At present, […]

3D Printed Clip Turns Smartphone into Powerful Microscope
Modern smartphones feature incredible image sensors that are much better than professional equipment from only a few years ago. They’re great for microscopy and simple attachments in front of the lens can give great views of blood, cells, and other specimens. The only problem is that the sample has to be illuminated and having LEDs […]
New Probes from Johns Hopkins Provide Closeup View of Internal Tissues Like Never Before
A biopsy is often the only way to accurately identify the presence of a tumor, but there are a number of serious possible downsides to taking tissue samples from inside the body. A better way would be to analyze the tissue in situ, essentially miniaturizing a microscope and using it in the body’s interior. Researchers […]
New Device Reproduces Bleeding Wounds to Study, Improve Healing
Scientists from Emory University, Georgia Tech, and the Blood Center of Wisconsin have developed a platform for studying the bleeding and clotting of wounds that is able to reproduce natural processes like never before. The technology should help to better understand how various processes, such as clot formation and repair of broken vessels, work together […]
Hologic Brevera Biopsy System Slices and Images Breast Tissue, Now Cleared in Europe
Breast biopsies, which can conclusively diagnose the presence of a tumor, suffer from a number of procedural limitations. One big issue is that during the excision of every sample, the physician can’t easily confirm whether the taken tissue really does come from the targeted lesion. Hologic‘s Brevera biopsy system has now been approved in Europe to […]
Plasmonic Biosensor to Detect Exosomes with Naked Eye
Exosomes are vesicles that are released by the body’s cells that end up in our blood, urine, and other bodily fluids. The importance and roles they play within our bodies still has to be elucidated, but there’s already a lot of signs that exosomes are biomarkers of disease and indicators of various cellular processes. Studying […]
SamanTree Medical’s Histolog Scanner: Interview with CEO Bastien Rachet
When surgeons excise a tumor, the challenge is always to remove the neoplasm with good margins while preserving as much of the healthy surrounding tissue as possible. To make sure that everything appropriate has been removed, pathologists look at the frozen sections and later at the full slices of samples taken during surgery. The preparation […]
Vibrator Detects Protein Biomarkers of Disease, Already Tried as Concussion Detector
Scientists at Purdue University have developed a novel new way of detecting biomarkers within blood and other bodily fluids, potentially opening the possibility of being able to quickly and easily detect a wide variety of diseases and monitor their progress. The team’s microelectromechanical system (MEMS) relies on vibration to spot a looked-for biomarker within the […]
Weighing Cancer Cells Can Reveal Their Susceptibility to Chemo
At present, there is no way to predict if multiple myeloma will respond to a particular drug cancer therapy, meaning clinicians often have to take a shot in the dark and hope that something works. Researchers at MIT have developed a new method to measure how well multiple myeloma patients will respond to a specific […]
EasyScan GO: AI Powered Malaria Parasite Counter
EasyScan GO, an AI powered microscope developed by Chinese manufacturer Motic, has the capability to automatically and accurately quantify malaria parasites in a blood sample. Utilizing machine learning algorithms, the microscope is so efficient that it can identify the amount of parasites present in under 20 minutes. Premiered at the International Conference on Computer Vision […]
Small, Cheap, Portable Spectrometer for Biological Sample Imaging Anywhere
Optical spectrometers provide a unique view of biological samples. How objects reflect different frequencies of light reveals quite a bit about them, but precise, highly sensitive spectrometers tend to be bulky and expensive. This technical limitation has prevented the use of spectrometry in many potential medical applications, particularly in field medicine and in areas with […]
Mirrors Improve Imaging of Biological Specimens by Light Sheet Microscopy
Though we’ve reached the diffraction limit of light in optical microscopes long ago, scientists are continuing to improve the images produced by them. Researchers National Institutes of Health and the University of Chicago just announced a new development that allows for much higher quality imaging of biological samples using light sheet microscopy, a common imaging technique. […]
FDA Clears Savi Scout Breast Tumor Localizer
Cianna Medical won FDA clearance for its SAVI SCOUT reflector, a non-radioactive implant for wire-free localization of tumors within the breast. Because the implant doesn’t emit any harmful radiation and is a fairly simple device, the emitter can remain implanted for an indefinite period of time. This gives clinicians greater freedom of scheduling the different […]
Deep Learning Network Taught to Classify Red Blood Cells by Shape
Researchers at the Northeastern University in China have developed a deep convolutional neural network that can identify and classify different shaped red blood cells. The technology may provide cheap, easy to use devices for monitoring of patients with sickle cell disease. Although it’s commonly assumed that sickle cell disease leads to the production of only […]
Abionic Detects Your Allergies in Minutes
Abionic, a Swiss company, has received US Food and Drug Administration (FDA) registration for detecting allergies to cats, dogs, trees, and grasses. The firm’s nanotechnology-focused assay can yield results in as little as five minutes, with some tests taking up to 20 minutes, and uses just a single drop of blood (no this isn’t a […]
Sound Waves Sort Cells for Diagnostics, Cell-Based Therapies
Researchers at the Singapore University of Technology and Design have developed a microfluidic device that can isolate cells from complex biological samples using sound waves. The technique could help doctors to accurately isolate specific types of cells from blood and other bodily fluids, which is useful for diagnostics and cell-based therapies. Separating individual cells from […]
Rapid Phone-Based Test for Multiple Infectious Pathogens
Scientists at the University of Illinois at Urbana-Champaign and the University of Washington at Tacoma have partnered to develop a compact, portable, and easy to use system for simultaneously detecting a variety of bacteria and viruses that cause disease. The system provides results in about a half an hour, which are nearly as accurate as laboratory […]
Organoids of Human Kidneys Help to Study Renal Diseases
Polycystic kidney disease is a genetic condition in which the tubules of the kidneys grow to become deformed, leading to cysts to grow on the organ. Studying this disease has been a challenge because of the difficulty of modeling it in the laboratory. Now researchers led by a team at the University of Washington have […]
Cellvizio Confocal Laser Endomicroscopy Now Cleared in EU for Robotic-Assisted Surgeries
Mauna Kea, a French firm, having recently made available its Cellvizio system in the U.S., now also won European CE Mark approval for the technology to be used during robotic-assisted surgeries. The Cellvizio Confocal Laser Endomicroscopy (CLE) System allows urologists to analyze the cellular structure of tissues as part of retroscopic and cystoscopic procedures. No samples […]
New Test Reveals Antibiotic-Resistant Bacteria in 30 Minutes
Researchers at Caltech have developed a new rapid test for antibiotic-resistant bacteria, which can give results within 30 minutes. Antibiotics are becoming less effective with the rise of multi-drug resistant strains of bacteria. At present, a doctor doesn’t know if their patient is infected with a drug-resistant strain without sending a sample to a lab, […]
