Building better medical implants and improving healing time

Building better medical implants and improving healing time
A University of Toronto research team has uncovered new information that could accelerate post-surgical healing for procedures involving medical devices as diverse as dental implants and skin dressings. Their paper, published in Nature Communications Biology, describes how different implant surface textures affect a fundamental process in the body’s ability to heal the area surrounding the implant.

The latest innovation in cast/orthosis

The latest innovation in cast/orthosis
Startup ActiveArmor has created a 3D printed cast/orthotic support device for injuries and pain that meets the demands of the medical community. ActivArmor is the first watersafe, custom fit/designed/fabricated orthosis available in the US Market. The company reports that “being an ActivArmor providing clinic increases patient referrals and throughput as patients seek the product out directly and physicians are making referrals to certified clinics.”

‘E-dermis’ brings sense of touch and pain to prosthetic hands

‘E-dermis’ brings sense of touch and pain to prosthetic hands
Amputees often experience the sensation of a 'phantom limb'—a feeling that a missing body part is still there. That sensory illusion is closer to becoming a reality thanks to a team of engineers at the Johns Hopkins University that has created an electronic skin. When layered on top of prosthetic hands, this e-dermis brings back a real sense of touch through the fingertips.

Nanoparticles used to deliver killer protein to cancer

Nanoparticles used to deliver killer protein to cancer
A biomimetic nanosystem can deliver therapeutic proteins to selectively target cancerous tumours, according to a team of Penn State researchers. Using a protein toxin called gelonin from a plant found in the Himalayan mountains, the researchers caged the proteins in self-assembled metal-organic framework (MOF) nanoparticles to protect them from the body’s immune system.

A type of 'Velcro' that traps prostate cancer cells

A type of 'Velcro' that traps prostate cancer cells
A research group in China has developed a sensor that acts like ‘Velcro’ for prostate cancer cells, trapping them on a modified frosted glass slide so that they can be identified from blood samples. The low-cost method, reported in ACS Applied Materials & Interfaces, could help doctors better diagnose and monitor the disease. In men with prostate cancer, some tumour cells exit the prostate gland and circulate in the blood.

Constructing tissue shapes with light

Constructing tissue shapes with light
Constructing biological tissues, such as skin, muscle, or bone, in customised shapes is now one step closer. Researchers at EMBL have succeeded in guiding the folding and thus shape of tissues with optogenetics: a technique to control protein activity with light. Nature Communications published their results, with implications for regenerative medicine. The changing of tissue shapes in an embryo is essential for healthy development.

Electronic skin stretches and heals like human skin

Electronic skin stretches and heals like human skin
An electrically conductive hydrogel that takes stretchability, self-healing and strain sensitivity to new limits has been developed at KAUST. “Our material outperforms all previously reported hydrogels and introduces new functionalities,” said Husam Alshareef, professor of materials science and engineering. Smart materials that flex, sense and stretch like skin have many applications in which they interact with the human body.

3D bioprinting for developing muscle and tendon tissues

3D bioprinting for developing muscle and tendon tissues
There is a strong need for medication that treats age-related degenerative muscle and tendon diseases. A critical bottleneck in the discovery and development of novel drugs for skeletal muscle is the lack of efficient and robust functional in vitro assays for compound screening. In a SLAS Technology original research article, researchers in Switzerland describe the development of a screening platform with automated production of 3D muscle- and tendon–like tissues using 3D bioprinting.

A type of vaccine based on spider silk

A type of vaccine based on spider silk
To fight cancer, researchers increasingly use vaccines that stimulate the immune system to identify and destroy tumour cells. However, the desired immune response is is not always guaranteed.
