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...)

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...)

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...)

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...)

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...)

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...)

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...)
