Fast, accurate new nanoparticle-based sensor system for screening cancer drugs

Traditional genomic, proteomic and other screening methods currently used to characterize drug mechanisms are time-consuming and require special equipment, but now researchers led by chemist Vincent Rotello at the University of Massachusetts Amherst offer a multi-channel sensor method using gold… Read more →

Seven life-changing surgeries made possible by 3D printing

Though printing items like chocolate and pizza might be satisfying enough for some, 3D printing still holds a lot of unfulfilled potential. Talk abounds of disrupting manufacturing, changing the face of construction and even building metal components in space. While… Read more →

Researchers Replace Sheep Meniscus with 3D-Printed Implant (VIDEO)

Researchers from Columbia University Medical Center have shown that a 3D printed implant might one day be used to treat torn menisci in the knee. Currently, there is no effective treatment for torn menisci except for completely removing them, which… Read more →

WSU researchers working on better bone-like materials used in hip and knee replacements

Washington State University researchers are working to improve materials used in hip and knee replacements so that they last longer and allow patients to quickly get back on their feet after surgery.

Led by Susmita Bose, professor in the School… Read more →

3D Printing Liver Phantoms to Prepare for Cancer Radiotherapy

Fine tuning the amount of radioactivity to deliver to cancerous tissue is a persistent challenge since too much radiation will do unnecessary damage to healthy tissue, while not enough won’t kill the tumor. Estimates and simulations can be done, but… Read more →

NovaShield Injectable Nasal Packing and Stent for Functional Endoscopic Sinus Surgery

Medtronic just released its new NovaShield Injectable Nasal Packing and Stent for functional endoscopic sinus surgery (FESS). The product is made from chitosan, a polysaccharide derived from the shells of crustaceans, and is in the form of an injectable gel.

Following FESS surgery,… Read more →

‘Smart skin’ could give prosthetics sense of touch

Embedded with sensory receptors, skin is the largest organ on the human body. But what happens when a limb is lost, or the skin is left ruined to the point where those receptors can no longer transmit tactile or thermal… Read more →

Clay composites modelled in ‘virtual lab’

Scientists in London have constructed a computer model that predicts the useful, physical properties of clay composites from their atomic make-up.

Clay-polymer composites can be very strong, stiff and light, making them useful in components for cars and… Read more →

New approach makes Ti implant more like bone

Metals such as Ti are widely used as implants in orthopedics and dentistry, but better mechanical properties and bioactivity could reduce subsequent failure and rejection. Researchers think they may have hit upon a solution to these issues using densified porous… Read more →

Meniscus regenerated with 3-D-printed implant

Columbia University Medical Center researchers have devised a way to replace the knee’s protective lining, called the meniscus, using a personalized 3D-printed implant, or scaffold, infused with human growth factors that prompt the body to regenerate the lining on its… Read more →
