Microrobots Roll Along Blood Vessel Walls to Deliver Drugs

Precise delivery of therapeutic drugs into diseased tissue remains a challenge in a variety of cases. Tumors can be hard to seed with chemo agents, particularly when the blood flow is not favorable for delivery. Now, researchers at the Max Planck Institute for Intelligent Systems in Germany have developed microscopic drug delivery devices that can (Read more...)

Paper Device Rapidly Measures Lithium Levels in Blood

Researchers at Hokkaido University in Japan have developed a paper-based point-of-care device which can measure lithium levels in a drop of blood. The device could help patients with bipolar disorder to keep track of their blood lithium levels. Lithium carbonate is used to treat bipolar disorder, but must be administered carefully as the concentrat (Read more...)

Flexible Sensors Measure Vitamin C Levels in Sweat

Researchers at the University of California San Diego have developed flexible sensors that can be worn on the skin to sensitively track vitamin C levels in sweat. The devices could be useful in helping wearers to maintain optimal levels of the vitamin, which is important for a healthy immune system, and could be particularly useful […]

Reusable Textiles to Repel Viruses

Researchers at the University of Pittsburgh have developed a coating that can be used to create textiles that repel viruses, along with bodily fluids such as saliva and blood. Interestingly, the coated textiles are reusable, and can be washed and scrubbed repeatedly without losing their virus-repelling properties. These characteristics may make the (Read more...)

Nanopropellers to Deliver Gene Therapy Into Cells

Researchers at the Max Planck Institute for Intelligent Systems in Germany have developed powerful nanopropellers that can be steered into the interior of cells to deliver gene therapy. The magnets that these devices, each about the size of a bacteria, are made of were created for the first time for this very task. Most powerful […]

3D Printed Microscope Costs as Little as $18

Researchers at the University of Bath in the UK have developed a 3D-printed microscope design, called OpenFlexure, which is open-source and can be assembled for as little as $18. More complex versions of the design are possible, and the microscope can incorporate full automation and a Raspberry Pi computer. The research team hopes that the [&hellip (Read more...)

Smart Contact Lenses Measure Glucose, Deliver Drugs

Researchers at the Pohang University of Science and Technology (POSTECH) report development of smart contact lenses for simultaneous glucose measurement and controlled drug delivery. The research, led by Professor Sei Kwang Han, found the contact lenses resulted in low irritation in rabbits, were able to reliably detect glucose levels in tears, and (Read more...)

MIT’s Comfortable Shirts Loaded with Body Sensors

MIT engineers have developed a way of creating shirts and other clothing items that are embedded with tiny electronic sensors capable of measuring the heart and respiration rates, temperature, and movement. Other vital signs can be added by utilizing additional sensor types. The technology will allow physicians to monitor their patients closely thr (Read more...)

Oxygen Concentrator for N95 Masks to Make Breathing Easier

Paramedics, ICU staff, and anyone else currently working with patients in any capacity is probably wearing a face mask for extended periods of time. N95 masks, which are easy to wear while providing substantial protection, can reduce the amount of oxygen reaching the lungs by up to 20%. This causes fatigue, may lower blood-oxygen saturation, [&hell (Read more...)

Rapid Medical Device Manufacturing for COVID-19 Response: Interview with Vicki Holt, CEO, Protolabs

The COVID-19 pandemic rumbles on, and the response to contain and delay the virus is astronomical, with billions of dollars and enormous levels of labor and material resources being deployed to meet the challenge. One of the major bottlenecks in combatting the virus is a lack of testing supplies and essential equipment, such as respirators, [&helli (Read more...)

Oxford’s Emergency Ventilator Project Steaming Ahead

The University of Oxford and King’s College London have teamed up to develop and are now testing a new emergency ventilator that consists of devices that commonly exist in clinical spaces and scientific laboratories, and a few simple parts that can be created through 3D printing. Bringing together these devices allows the team to create [&hel (Read more...)
