Magnetic Nanoparticles to Stop Internal Bleeding

Researchers from ITMO University in St. Petersburg, Russia have developed magnetic nanoparticles to control internal bleeding, which can be localized at a bleeding site in the body using external magnetic fields. Internal bleeding is a medical emergency, and researchers are working to develop more effective therapies that are targeted at the bleedi (Read more...)

Liquid-Powered Bioprinting of Tissues at Any Scale

Researchers at Queen Mary University of London, University of Oxford, and Nanyang Technological University in Singapore, have developed an unusual way to print complex biological structures with multiple ingredients that can harness further tissue growth. The 3D structures that are created are made of modular components that can be brough (Read more...)

Nanoparticle Material Melts Away to Reveal Drug Cargo

At the Technion-Israel Institute of Technology, researchers have developed a new set of materials designed to deliver drugs inside the body and melt away when illuminated with light. The materials are made of a polymer seeded with nano-sized gold shell nanoparticles. When light from a near-infrared (NIR) laser is applied to the material, it me (Read more...)

Brain Organoids Show Formation of Brain Wrinkles

Our regular readers might have noted that the development of organ-on-a-chip devices has become a popular research trend. Tiny living parts of real human organs can be sustained for long periods of time inside of specially designed chambers that feed the organoids and provide researchers a window to examine them under a microscope. All sorts [&hell (Read more...)

Placenta-on-a-Chip to Screen for Drug Safety During Pregnancy

Researchers at the University of Pennsylvania have developed a microfluidic chip that mimics the placental barrier. Their device paves the way for drug screening to determine which drugs can cross the placental barrier, allowing researchers to assess drug safety for pregnant women. Pharmacological treatment for pregnant women can be risky, as some (Read more...)

Flexible, Breathable Electronic Tattoo Measures Vital Signs

A team of Japanese scientists has developed a way of creating breathable on-skin electronics that can stretch while continuing to function and that don’t cause any inflammation on the skin. These tattoo-like electronics have now been worn by volunteers for up to a week, with them reporting that they don’t even feel the presence of [&hel (Read more...)
