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...)

3D Printing Living Cells Into Useful Biomedical Objects

There have been a number of techniques recently developed for printing objects with living cells inside of them. The technology can lead to custom tissue replacements and other medical applications, but all these methods are quite slow. That’s because living cells have to somehow be carefully moved through microfluidic channels to mix wi (Read more...)

Artificial Brain Synapses Replicated in a Chip

Our brains mainly consist of brain cells and the connections between them, making them quite modular and incredibly adaptable. Brain synapses, the connections between neurons, seem to be responsible for at least some of the computational magic that allows us to think, move, and respond to all sorts of stimuli. Being able to replicate the […]

Microfluidic Mixer Combines Fluids without Backflow to Make Advanced Portable Diagnostics Practical

Lab on a chip devices are designed to perform advanced diagnostics and drug testing using small samples of blood and other body fluids. We’ve written about many such devices, including for assessing the effectiveness of chemo and for picking out circulating tumor cells, but microfluidic technologies that rely on capillary or vacuum powered te (Read more...)

Cryogenic 3D Printing to Make Replica Brain and Lung Tissues

Printing biological tissues, a necessary precursor to creating replacement organs, is not easy, but constructing extremely soft and fragile tissues that resemble the brain and lungs is even more difficult. Researchers at Imperial College London and Kings College London are now using extremely cold temperatures in combination with 3D printing to cre (Read more...)

Draper’s Microfluidic Artificial Kidney Reproduces Real Thing at Cellular and Tissue Levels

Kidney injuries from exposure to too many drugs are common among certain groups of patients, particularly those spending time in the ICU. Kidney injuries can also happen during drug testing, wounding subjects while eliminating candidate drugs far along their development pipeline. Engineers at Draper have now developed a so-called kidney-on-a-chip, (Read more...)
