Light is a great tool for imaging the outside of the body and for looking at the interior using endoscopes, but looking through more than a few millimeters of tissue typically requires other modalities such as X-rays and ultrasound. Using light to peer through skin, muscle, and other soft tissues has remained an elusive goal […]

Microfluidic Chip Allows Embryonic Stem Cells to Differentiate
Complex multicellular organisms, such as ourselves, start out from stem cells that differentiate into different kinds of cells. This process is controlled by groups of cells that secrete special signaling molecules called morphogens, which guide nearby stem cells to turn into the kinds of cells that should be located in that region. This is an [&he (Read more...)
3D-Printing Utilized to Grow New Human Hair
Researchers from the Columbia University Irving Medical Center have developed a tissue engineering and 3D printing method to grow new hair follicles and stop hair loss. Their work, recently published in Nature Communications, demonstrates that they were able to grow human hair follicles in a dish and on mice for the first time. These hair [… (Read more...)
Virtual Biopsy for Skin Lesions Using Vibrational Optical Coherence Tomography
Tissue biopsies of skin lesions can be unpleasant and quite painful. Moreover, a biopsy typically doesn’t sample the whole lesion and doesn’t provide much information about a given lesion’s size and depth. Now, scientists at Rutgers University have developed and tested a new device that relies on two different mechanisms to analyz (Read more...)
Electrospinning Gun Protects Wounds with Nanofiber Mesh
An Israeli company called Nanomedic has begun showing off its impressive device for applying an electrospun material to the surface of wounds. Electrospinning involves using electricity to produce extremely fine polymer threads. This technology is almost always used during manufacturing. The SpinCare product is the first portable electrospinning de (Read more...)
Handheld Melanoma Sensor Checks Suspect Lesions for Polarization Properties
Melanoma is usually a readily accessible cancer, being on the skin and in full view, but it can be hard to differentiate from benign moles. Researchers at the University of British Columbia have developed and tested a new device that uses a laser to spot the telltale signs of a melanoma tumor as its light […]
TREMFYA One-Press Patient Controlled Injector Approved for Plaque Psoriasis
The Janssen Pharma, a part of Johnson & Johnson, won FDA approval for its TREMFYA One-Press single-dose injector. The device is used to deliver TREMFYA (guselkumab) as a treatment for moderate to severe plaque psoriasis. The TREMFYA One-Press allows patients to decide how fast and with how much pressure to deliver the medication. This lets [&he (Read more...)
Soliton Acoustic Shockwave Device to Aid in Tattoo Removal
Soliton, a company based in Houston, Texas, has developed an acoustic shockwave device to assist in laser tattoo removal. At present, laser tattoo removal takes a significant number of sessions, with long waits between visits and a significant overall cost. This new device aims to allow numerous laser passes per session, and the company claims [&he (Read more...)
Smart Tattoos to Detect Fever, Sun Exposure, and Maybe Diagnose Diseases
Tattoos have a long history on the human skin, underlined by a find of a body in the Alps more than 5,000 years old that had tattoos all over it. While tattoos have mostly served as decorations, status symbols, and as parts of rituals, researchers at University of Colorado Boulder believe they can be made […]
Tiny Wearable UV Sensor Can Help to Optimize Phototherapy
Researchers at Northwestern University have developed a “virtually indestructible” solar-powered UV sensor. Described as the world’s smallest wearable, the battery-free device is thinner than a credit card and smaller than an M&M candy, but can warn people about UV over-exposure and help clinicians to optimize dosing during li (Read more...)

Luma’s illuvinate Now Available for Drug-Free Plaque Psoriasis Treatment at Home
Luma Therapeutics, based outside of San Francisco, CA, is releasing its new illuvinate system for treatment of plaque psoriasis, an irritating skin condition. The device delivers ultraviolet light, within a narrow spectrum, to the skin using a powerful-stick on LED array, as well as humidification to soothe the area. Patients who are prescribed the (Read more...)
L’Oréal Releases Sun Exposure Monitor Through Apple
L’Oréal, the big skin care company, has just released a tiny device for monitoring skin’s exposure to the sun. Offered through Apple’s online shop and at some of its physical stores, the La Roche-Posay My Skin Track UV device doesn’t use any batteries while being able to upload its readings to a paired smart (Read more...)
Nanoneedle Skin Patch to Inject Drugs Into Cells
Delivering drugs directly into skin cells using microscopic nanoneedles may allow for highly effective treatment of skin conditions without injuring the cells that are treated. Silicon nanoneedles have been developed in the past that can do such a trick, but they’re stiff and can be painful, in addition to quickly losing their effectiveness. (Read more...)
“Spray-On Skin” from AVITA Medical Approved to Treat Serious Burns
AVITA Medical, a Valencia, California firm, won FDA approval for its remarkable RECELL Autologous Cell Harvesting Device for serious burns in adult patients. In preparation for treatment, a small healthy piece of the patient’s skin sample is taken, from which the so-called “Spray-On Skin” preparation is made. The process only take (Read more...)
Topical Skin Lotion to Detect Variety of Disease Biomarkers
Scientists at the Nanyang Technological University in Singapore have developed a new way of utilizing nanotechnology to detect important biomarkers within the skin using what looks like a simple lotion. Their NanoFlares, which are spherical, programmable nano-scale balls of nucleic acid, have gold cores. These NanoFlares are able to penet (Read more...)
How to identify and treat eyelid dermatitis
Learn about the types of eyelid dermatitis, and how to get rid of these itchy rashes. We also look at symptoms, causes, and prevention.
Knitted Fabric Delivers Laser Light to Treat Skin Conditions
A number of diseases are treated using light therapy. These include acne, actinic keratosis, jaundice, Paget’s disease, and psoriasis. Modern light blankets use arrays of LEDs to produce illumination, but light emitted by LEDs can be quite weak compared to light produced by a laser. Photodynamic therapy light lamps, on the other hand, ca (Read more...)
Electronic Skin Heals Thyself While Measuring Pressure, Temperature, Humidity
Researchers from the University of Colorado Boulder have developed an “electronic skin” that is able to heal itself when damaged, and when no longer needed it can be fully recycled. E-skins can provide new capabilities in the form of medical and athletic devices, as well as mimic tactile and other sensing within advanced prostheses. The (Read more...)
