New Bioink for 3D Printing and Protein Therapy

Researchers at Texas A&M University have developed a 3D-printable hydrogel bioink containing mineral nanoparticles that can deliver protein therapeutics to control cell behavior. The material does not provoke the immune system and the researchers hope that it could be useful in replacing damaged tissues for regenerative medicine. 3D printing is a promising method for creating … Continue reading

Body-Worn Electric Generator to Power Medical Implants, Wearable Devices

Many implantable and wearable devices need access to continuously available electrical power. Implants, such as cardiac pacemakers, often have to be exchanged for new ones during surgery because modern batteries have a limited lifetime. Engineers at Rice University have been working on a small and flat generator that is capable of producing significant amounts of … Continue reading

Preserving Vaccines at Room Temperature Finally Possible

The availability of vaccines in poor and remote regions is usually the result of a lack of proper storage and transportation options. For most vaccines to survive, they must be kept cold and within a prescribed temperature range. Storage areas have to have fridges with access to reliable electricity and the delivery cars and trucks … Continue reading

Microscopic Graphene Flakes to Stop Epileptic Seizures

During epileptic seizures, the brain’s excitatory neurons go haywire, generating extreme amounts of electric activity. There are already electronic devices available that help to prevent and mitigate seizures, but so far they’re only effective in some patients while having all the downsides of a serious implantation. A team of European researchers from Sissa (International School … Continue reading

Magnetic Beads Strip Blood Samples to Allow Circulating Tumor Cell Isolation

Researchers at the University of Georgia have developed a microfluidic chip to isolate circulating tumor cells (CTCs) from blood samples. Unlike other devices, this new chip uses magnetic microbeads to strip all the cells from the blood, leaving only the CTCs, in a technique the researchers have called “integrated ferrohydrodynamic cell separation”. The device is … Continue reading

Scorpion Protein Used to Help Visualize Brain Tumors

Clinicians at the Cedars-Sinai Medical Institute, along with scientists at Blaze Bioscience, Inc., have developed a new way to visualize brain tumors. The new imaging technique utilizes a special, high-sensitivity near-infrared camera developed at Cedars-Sinai, along with tozuleristide, or BLZ-100, the tumor-cell binding imaging agent developed by Blaze. The imaging agent contains a synthetic version … Continue reading

Scientists Figure Out How to 3D Print Vascular Networks for Printed Organs

The field of tissue engineering has seen a lot of progress, with complex 3D systems being developed that offer strength, contain multiple cell types, and that can even perform a biological function. All this is child’s play if there is no viable vascular network to supply the nutrients to all the cells and to route … Continue reading

Electronic Contact Lenses Can Now Integrate Micro-Battery to Power Them

Electronic contact lenses have been in development for over a decade by a number of labs around the world. Having electronics integrated into a contact lens may provide medical capabilities, such as measuring intraoccular pressure, analyzing tears for glucose levels, and aiding people with poor vision. While the science of making smart contact lenses has … Continue reading

Researchers Develop Smart Bioinks to 3D Print Living Tissues

If we’re going to 3D print tissues, organs, and entire body parts, scientists will have to create advanced, highly functional bioinks. Plus, these bioinks will have to withstand being printed and must survive within the harsh interior of the body. At the Fraunhofer Institute for Interfacial Engineering and Biotechnology and University of Stuttgart in Germany, researchers … Continue reading

Crumpled Carbon Nanotube Forests to Power Medical Devices

Most implantable and wearable medical devices benefit from having on-board batteries powering them, but because conventional batteries have specific internal geometries, they end up being blocky and not flexible. This limits development of the electronic devices, especially pliable ones, since the human body itself is mostly soft and flexible. While flexible electronics is already a … Continue reading
