Novel Coating Makes Affinity-Based Sensors Practical for Medicine
Affinity-based sensors are electrochemical devices that can detect a large variety of disease biomarkers. They typically have enzyme-coated electrodes onto which chemical biomarkers can stick, in the process changing the electrical characteristics of the device, something that can be accurately measured. Although they’re extremely sensitive, when used in practice with whole blood, they quickly become […]
Graphene Imaging Platform to Track Stem Cell Differentiation
Stem cells hold a great deal of promise in treating a huge variety of human diseases. Although much hyped to the general public some years ago, it turned out to be very difficult to safely use stem cells to generate replacement tissues without inadvertently introducing tumors or other maladies. Knowing how stem cells differentiate, and […]
Snubbed by Scientists, Recognized 20 Years Later
Robert Folberg’s success was 2 decades in the making after his team discovered vasculogenic mimicry. Their original report received a frosty reception, but has since been cited more than 1900 times. Medscape Medical News

Drones Deliver Lifesaving Therapy in Brooklyn Faster than Ambulances
At the just concluded American Academy of Pediatrics 2019 National Conference & Exhibition, research was presented demonstrating that within busy Brooklyn, New York, drones can arrive at the site of an emergency consistently faster than a conventional ambulance. This was accomplished by performing flights using an aerial drone that mimicked the same point-to-point journeys that […]
Controllable Microswimmers Move Around Individual Cells in 3D
Manipulating individual cells and microscopic particles may be extremely valuable for testing new therapies, targeting tumors, and for studying the underlying causes of disease, but it is very difficult to directly manipulate individual cells within an environment shared with other cells. A collaboration of researchers from University of California San Diego, University of Pennsylvania, and […]
3D Printed Cells and Bioinks for Making Implantable Blood Vessels
Researchers based in South Korea and Hong Kong have developed a method to create biomimetic blood vessels by directly 3D printing vascular cells and bioinks containing collagen and vascular tissue extracellular matrix components. The resulting constructs closely mimic natural blood vessels, suggesting that such techniques could pave the way for custom vascular grafts to treat […]
Tiny Medical Imaging Sensor Sets Guinness World Record
OmniVision Technologies, a Santa Clara, California firm, just announced that it has won the Guinness World Record for “The Smallest Commercially Available Image Sensor”. The OV6948 sensor was designed for use in catheters and endoscopes, allowing these devices to be as small as possible while also providing high quality imaging from within the body. Measuring […]
More Evidence Links Common Bladder Drug to Retinal Damage
Pentosan polysulfate sodium (PPS), used widely for interstitial cystitis, may lead to retinal damage, according to a new study that adds weight to this previously suggested link. Reuters Health Information
Intraocular Trifocals Outdo Extended Depth for Near Vision
Trifocal lenses offer better near vision than extended depth of focus lenses, a head-to-head study shows. Medscape Medical News
3D Liquid-Cell Electron Microscopy Imaging Now Possible
Electron microscopy revealed a world that exists at scales smaller than the wavelength of light. Advancements in this field have allowed scientists to visualize ever more objects and processes, but actually seeing living cells in 3D and within a liquid environment has been impossible. Now, a team of researchers from Penn State University, Virginia Tech, […]
Postoperative Adjustment of Intraocular Lenses Holds Promise
When ophthalmologists calculate intraocular lens power for cataract surgery patients, they should consider the cornea, but postoperatively adjustable lenses could be the way of the future. Medscape Medical News

Nobel Prize in Physiology or Medicine 2019 Announced for Cell Oxygen Regulation
Two Americans and an English knight have won this year’s Nobel Prize in Physiology or Medicine for their discovery of how cells detect how much oxygen is available to them and the mechanism that regulates how they adapt to changes in oxygen levels. While the scientific community recognized the importance of oxygen for animal cells […]
